[kicad-users] Air wires that won't disappear in PCBNew?

[Doug McKnight [e-mail] [kicad-users]]

Hello,
I believe I'm making good connections, but am finding a bunch of air wires won't disappear.  Usually they disappear in the usual way. I'm routing with two layers, using in-line vias, but the problem is also happening if I stay on a single layer??

Are there any "newbie" mistakes that I might be making? Could there be a problem with a footprint or something strange? I edited the footprint for the parts that I'm finding this problem with, but only to remove some heat-dissipation vias that won't be needed. I didn't touch the pads etc...
Any general air-wire guidelines I should be aware of?

One possible problem occurs when you have several connection points in a
straight line - the natural thing to do is to simply place a track over
those points. However, this will leave the intermediate points
unconnected, as far as DRC is concerned. To make DRC understand that
all the points are connected, you must click on each point as you pass
it, so you make a series of track segments, rather than a single
segment, over the series of connection points.

Thanks for the reply Peter. That's not the problem. I'm familiar with that possible confusion. Doug

Hi,

Sometimes the track doesn't hit the center of the pad though it seems it
does.

I always work with the "Magnetic pads when creating tracks" option on,
under Preferences->General Settings.

Give it a try.

Regards,
Pedro.

Hi Perdo,Thanks, Yes, I'm using the magnetic pads option. It "feels" like the tracks connect properly into place and, indeed, the air-wires usually disappear.
The stubborn ones are a bit more of a mystery. I have completely rewired the connection(s) (several times) to try to get rid of them, but some are tricky.  Once the layout is closer to finished I'll dig in more with DRC to try to figure it out.

I'm absolutely no expert, and I've had persistent air wires. I had to keep repeating drawing the track until one went way. I guessed there might be a glitch that occasionally doesn't trigger the erase command for the air wire.

Hi Perdo,
Thanks, Yes, I'm using the magnetic pads option. It "feels" like the tracks connect properly into place and, indeed, the air-wires usually disappear.

The stubborn ones are a bit more of a mystery. I have completely rewired the connection(s) (several times) to try to get rid of them, but some are tricky. Once the layout is closer to finished I'll dig in more with DRC to try to figure it out.

Hi,

Sometimes the track doesn't hit the center of the pad though it seems it
does.

I always work with the "Magnetic pads when creating tracks" option on,
under Preferences->General Settings.

Give it a try.

As has been said getting the wires to connect is the main part, the
co-ords have to be an exact match for this to happen. magnetic pads
should do the job.

In earlier versions of Kicad there was a weird issue which could end up
with multiple copies of a track or module placed right on top of each
other. This made it almost impossible to select the dud components to get
rid of them, or the correct one to place a wire to. (even when
zooming in as much as possible) These were pretty obvious in the PCB files
as you saw several duplicate lines. Deleting the offending ones solved the
problem.

I've not seen that issue with the newer Kicad i.e. using .pretty files,
but is may be worth a peek in the files just in case.

The problem usually occurred whan a module was accidentally placed twice
rather than once.

[Doug McKnight [e-mail] [kicad-users]]

I'm still really struggling with this.  I'm not sure what else to check...  Most of my connections are fine, but I've got a few (out of hundreds) are being stubborn.I've checked for duplicate footprints, duplicate traces. I've got magnetic pads on, and the traces seem to align "magnetically" as expected.  I've remade some of these connections completely, to no avail.
DRC agrees that the appropriate pads aren't connected..
Also, when I select various parts of an affected wire it shows as having the correct name at all segments. It really seems correct?
Is there something stupid I'm doing here? Probably...
Any more advice is greatly appreciated.

One possible problem occurs when you have several connection points in a
straight line - the natural thing to do is to simply place a track over
those points. However, this will leave the intermediate points
unconnected, as far as DRC is concerned. To make DRC understand that
all the points are connected, you must click on each point as you pass
it, so you make a series of track segments, rather than a single

[yann jautard [e-mail] [kicad-users]]

can you share your pcb file ?

I'm still really struggling with this. I'm not sure what else to
check... Most of my connections are fine, but I've got a few (out of
hundreds) are being stubborn.
I've checked for duplicate footprints, duplicate traces. I've got
magnetic pads on, and the traces seem to align "magnetically" as
expected. I've remade some of these connections completely, to no avail.
DRC agrees that the appropriate pads aren't connected..
Also, when I select various parts of an affected wire it shows as
having the correct name at all segments. It really seems correct?
Is there something stupid I'm doing here? Probably...
Any more advice is greatly appreciated.

As has been said getting the wires to connect is the main part, the
co-ords have to be an exact match for this to happen. magnetic pads
should do the job.
In earlier versions of Kicad there was a weird issue which could end up
with multiple copies of a track or module placed right on top of each
other. This made it almost impossible to select the dud components to get
rid of them, or the correct one to place a wire to. (even when
zooming in as much as possible) These were pretty obvious in the PCB files
as you saw several duplicate lines. Deleting the offending ones solved the
problem.
I've not seen that issue with the newer Kicad i.e. using .pretty files,
but is may be worth a peek in the files just in case.
The problem usually occurred whan a module was accidentally placed twice
rather than once.

Hi Perdo,Thanks, Yes, I'm using the magnetic pads option. It "feels"

like the tracks connect properly into place and, indeed, the air-wires
usually disappear.

Post by Doug McKnight ***@yahoo.com [kicad-users]
The stubborn ones are a bit more of a mystery. I have completely

rewired the connection(s) (several times) to try to get rid of them,
but some are tricky. Once the layout is closer to finished I'll dig
in more with DRC to try to figure it out.

Hi,
Sometimes the track doesn't hit the center of the pad though it

I always work with the "Magnetic pads when creating tracks" option on,
under Preferences->General Settings.
Give it a try.

Thanks for the reply Peter.
That's not the problem. I'm familiar with that possible confusion.

One possible problem occurs when you have several connection

those points. However, this will leave the intermediate points
unconnected, as far as DRC is concerned. To make DRC understand that
all the points are connected, you must click on each point as you pass
it, so you make a series of track segments, rather than a single
segment, over the series of connection points.

Hello,
I believe I'm making good connections, but am finding a bunch of air
wires won't disappear. Usually they disappear in the usual way.

  I'm still really struggling with this.  I'm not sure what else to check...  Most of my connections are fine, but I've got a few (out of hundreds) are being stubborn. I've checked for duplicate footprints, duplicate traces. I've got magnetic pads on, and the traces seem to align "magnetically" as expected.  I've remade some of these connections completely, to no avail.
DRC agrees that the appropriate pads aren't connected..
Also, when I select various parts of an affected wire it shows as having the correct name at all segments. It really seems correct?
Is there something stupid I'm doing here? Probably...
Any more advice is greatly appreciated.

  As has been said getting the wires to connect is the main part, the
co-ords have to be an exact match for this to happen. magnetic pads
should do the job.

In earlier versions of Kicad there was a weird issue which could end up
with multiple copies of a track or module placed right on top of each
other. This made it almost impossible to select the dud components to get
rid of them, or the correct one to place a wire to. (even when
zooming in as much as possible) These were pretty obvious in the PCB files
as you saw several duplicate lines. Deleting the offending ones solved the
problem.

I've not seen that issue with the newer Kicad i.e. using .pretty files,
but is may be worth a peek in the files just in case.

The problem usually occurred whan a module was accidentally placed twice
rather than once.

Hi Perdo,Thanks, Yes, I'm using the magnetic pads option. It "feels" like the tracks connect properly into place and, indeed, the air-wires usually disappear.
The stubborn ones are a bit more of a mystery. I have completely rewired the connection(s) (several times) to try to get rid of them, but some are tricky.  Once the layout is closer to finished I'll dig in more with DRC to try to figure it out.

  Hi,
Sometimes the track doesn't hit the center of the pad though it seems it
does.
I always work with the "Magnetic pads when creating tracks" option on,
under Preferences->General Settings.
Give it a try.
Regards,
Pedro.

Thanks for the reply Peter.
That's not the problem. I'm familiar with that possible confusion.

One possible problem occurs when you have several connection points in a
straight line - the natural thing to do is to simply place a track over
those points. However, this will leave the intermediate points
unconnected, as far as DRC is concerned. To make DRC understand that
all the points are connected, you must click on each point as you pass
it, so you make a series of track segments, rather than a single
segment, over the series of connection points.

Hello,
I believe I'm making good connections, but am finding a bunch of air
wires won't disappear. Usually they disappear in the usual way.
I'm routing with two layers, using in-line vias, but the problem is also
happening if I stay on a single layer??
Are there any "newbie" mistakes that I might be making? Could there be a
problem with a footprint or something strange? I edited the footprint
for the parts that I'm finding this problem with, b ut only to remove
some heat-dissipation vias that won't be needed. I didn't touch the pads
etc...
Any general air-wire guidelines I should be aware of?
Regards
Doug

can you share your pcb file ?

I'm still really struggling with this. I'm not sure what else to
check... Most of my connections are fine, but I've got a few (out of
hundreds) are being stubborn.
I've checked for duplicate footprints, duplicate traces. I've got
magnetic pads on, and the traces seem to align "magnetically" as
expected. I've remade some of these connections completely, to no avail.
DRC agrees that the appropriate pads aren't connected..
Also, when I select various parts of an affected wire it shows as
having the correct name at all segments. It really seems correct?
Is there something stupid I'm doing here? Probably...
Any more advice is greatly appreciated.

As has been said getting the wires to connect is the main part, the
co-ords have to be an exact match for this to happen. magnetic pads
should do the job.
In earlier versions of Kicad there was a weird issue which could end up
with multiple copies of a track or module placed right on top of each
other. This made it almost impossible to select the dud components to get
rid of them, or the correct one to place a wire to. (even when
zooming in as much as possible) These were pretty obvious in the PCB files
as you saw several duplicate lines. Deleting the offending ones solved the
problem.
I've not seen that issue with the newer Kicad i.e. using .pretty files,
but is may be worth a peek in the files just in case.
The problem usually occurred whan a module was accidentally placed twice
rather than once.

Hi Perdo,Thanks, Yes, I'm using the magnetic pads option. It

"feels" like the tracks connect properly into place and, indeed, the
air-wires usually disappear.

Post by Doug McKnight ***@yahoo.com [kicad-users]
The stubborn ones are a bit more of a mystery. I have completely

rewired the connection(s) (several times) to try to get rid of them,
but some are tricky. Once the layout is closer to finished I'll dig
in more with DRC to try to figure it out.

Hi,
Sometimes the track doesn't hit the center of the pad though it

does.
I always work with the "Magnetic pads when creating tracks" option on,
under Preferences->General Settings.
Give it a try.

Thanks for the reply Peter.
That's not the problem. I'm familiar with that possible confusion.

those points. However, this will leave the intermediate points
unconnected, as far as DRC is concerned. To make DRC understand that
all the points are connected, you must click on each point as you

pass

it, so you make a series of track segments, rather than a single
segment, over the series of connection points.

Hello,
I believe I'm making good connections, but am finding a bunch of air
wires won't disappear. Usually they disappear in the usual way.

  I'm still really struggling with this.  I'm not sure what else to check...  Most of my connections are fine, but I've got a few (out of hundreds) are being stubborn. I've checked for duplicate footprints, duplicate traces. I've got magnetic pads on, and the traces seem to align "magnetically" as expected.  I've remade some of these connections completely, to no avail.
DRC agrees that the appropriate pads aren't connected..
Also, when I select various parts of an affected wire it shows as having the correct name at all segments. It really seems correct?
Is there something stupid I'm doing here? Probably...
Any more advice is greatly appreciated.

  As has been said getting the wires to connect is the main part, the
co-ords have to be an exact match for this to happen. magnetic pads
should do the job.

In earlier versions of Kicad there was a weird issue which could end up
with multiple copies of a track or module placed right on top of each
other. This made it almost impossible to select the dud components to get
rid of them, or the correct one to place a wire to. (even when
zooming in as much as possible) These were pretty obvious in the PCB files
as you saw several duplicate lines. Deleting the offending ones solved the
problem.

I've not seen that issue with the newer Kicad i.e. using .pretty files,
but is may be worth a peek in the files just in case.

The problem usually occurred whan a module was accidentally placed twice
rather than once.

Hi Perdo,Thanks, Yes, I'm using the magnetic pads option. It "feels" like the tracks connect properly into place and, indeed, the air-wires usually disappear.
The stubborn ones are a bit more of a mystery. I have completely rewired the connection(s) (several times) to try to get rid of them, but some are tricky.  Once the layout is closer to finished I'll dig in more with DRC to try to figure it out.

  Hi,
Sometimes the track doesn't hit the center of the pad though it seems it
does.
I always work with the "Magnetic pads when creating tracks" option on,
under Preferences->General Settings.
Give it a try.
Regards,
Pedro.

Thanks for the reply Peter.
That's not the problem. I'm familiar with that possible confusion.

One possible problem occurs when you have several connection points in a
straight line - the natural thing to do is to simply place a track over
those points. However, this will leave the intermediate points
unconnected, as far as DRC is concerned. To make DRC understand that
all the points are connected, you must click on each point as you pass
it, so you make a series of track segments, rather than a single
segment, over the series of connection points.

Hello,
I believe I'm making good connections, but am finding a bunch of air
wires won't disappear. Usually they disappear in the usual way.
I'm routing with two layers, using in-line vias, but the problem is also
happening if I stay on a single layer??
Are there any "newbie" mistakes that I might be making? Could there be a
problem with a footprint or something strange? I edited the footprint
for the parts that I'm finding this problem with, b ut only to remove
some heat-dissipation vias that won't be needed. I didn't touch the pads
etc...
Any general air-wire guidelines I should be aware of?
Regards
Doug

[yann jautard [e-mail] [kicad-users]]

ok, got your file.


When I open it, it has like an array of horizontal trace segments
outside th pcb itself. Pretty strange, There is something to check here.

And regarding the air wire, everything looks good to me, only two are
not disapearing using the legacy canvas, even if the connections looks
good. But using Cairo they disapear. So maybe there is somethink deeper
in the kicad code that needs to be looked at. Can't test with opengl I
have a too old netbook and it doesn't work.

But DRC complains pads not connected but as far as we can see, they
obviously are... tried redrawing the track with the finest grip, nothing
more.

Maybe post you file to the list too so someone more skilled than me can
have a look ?

can you share your pcb file ?

I'm still really struggling with this. I'm not sure what else to
check... Most of my connections are fine, but I've got a few (out
of hundreds) are being stubborn.
I've checked for duplicate footprints, duplicate traces. I've got
magnetic pads on, and the traces seem to align "magnetically" as
expected. I've remade some of these connections completely, to no avail.
DRC agrees that the appropriate pads aren't connected..
Also, when I select various parts of an affected wire it shows as
having the correct name at all segments. It really seems correct?
Is there something stupid I'm doing here? Probably...
Any more advice is greatly appreciated.

As has been said getting the wires to connect is the main part, the
co-ords have to be an exact match for this to happen. magnetic pads
should do the job.
In earlier versions of Kicad there was a weird issue which could end up
with multiple copies of a track or module placed right on top of each
other. This made it almost impossible to select the dud components to get
rid of them, or the correct one to place a wire to. (even when
zooming in as much as possible) These were pretty obvious in the PCB files
as you saw several duplicate lines. Deleting the offending ones solved the
problem.
I've not seen that issue with the newer Kicad i.e. using .pretty files,
but is may be worth a peek in the files just in case.
The problem usually occurred whan a module was accidentally placed twice
rather than once.

Hi Perdo,Thanks, Yes, I'm using the magnetic pads option. It

"feels" like the tracks connect properly into place and, indeed, the
air-wires usually disappear.

Post by Doug McKnight ***@yahoo.com [kicad-users]
The stubborn ones are a bit more of a mystery. I have completely

rewired the connection(s) (several times) to try to get rid of them,
but some are tricky. Once the layout is closer to finished I'll dig
in more with DRC to try to figure it out.

Hi

This a bit of a long shot but...
Have you checked the grid compatibility between PCBNew and the Footprint
editor.
In the past I had some odd issues because of having grids that won't
align with each other.

Just my 2 cents...


Best regards
Jorge

I'm still really struggling with this. I'm not sure what else to
check... Most of my connections are fine, but I've got a few (out of
hundreds) are being stubborn.
I've checked for duplicate footprints, duplicate traces. I've got
magnetic pads on, and the traces seem to align "magnetically" as
expected. I've remade some of these connections completely, to no avail.
DRC agrees that the appropriate pads aren't connected..
Also, when I select various parts of an affected wire it shows as
having the correct name at all segments. It really seems correct?
Is there something stupid I'm doing here? Probably...
Any more advice is greatly appreciated.
Doug

As has been said getting the wires to connect is the main part, the
co-ords have to be an exact match for this to happen. magnetic pads
should do the job.
In earlier versions of Kicad there was a weird issue which could end up
with multiple copies of a track or module placed right on top of each
other. This made it almost impossible to select the dud components to get
rid of them, or the correct one to place a wire to. (even when
zooming in as much as possible) These were pretty obvious in the PCB files
as you saw several duplicate lines. Deleting the offending ones solved the
problem.
I've not seen that issue with the newer Kicad i.e. using .pretty files,
but is may be worth a peek in the files just in case.
The problem usually occurred whan a module was accidentally placed twice
rather than once.

Hi Perdo,Thanks, Yes, I'm using the magnetic pads option. It "feels"

like the tracks connect properly into place and, indeed, the air-wires
usually disappear.

Post by Doug McKnight ***@yahoo.com [kicad-users]
The stubborn ones are a bit more of a mystery. I have completely

rewired the connection(s) (several times) to try to get rid of them,
but some are tricky. Once the layout is closer to finished I'll dig
in more with DRC to try to figure it out.

Hi,
Sometimes the track doesn't hit the center of the pad though it

I always work with the "Magnetic pads when creating tracks" option on,
under Preferences->General Settings.
Give it a try.

Thanks for the reply Peter.
That's not the problem. I'm familiar with that possible confusion.

One possible problem occurs when you have several connection

those points. However, this will leave the intermediate points
unconnected, as far as DRC is concerned. To make DRC understand that
all the points are connected, you must click on each point as you pass
it, so you make a series of track segments, rather than a single
segment, over the series of connection points.

Hello,
I believe I'm making good connections, but am finding a bunch of air
wires won't disappear. Usually they disappear in the usual way.
I'm routing with two layers, using in-line vias, but the problem

The footprint editor shows the grid to be 50.0 mils when I use "open from the current board" to edit one of the footprints in question. The grid is set to 5.0 mils on the board. It seems they should play nice??
Here's the board, in case anyone feels like taking a look. I'd appreciate any help with this one...cheersDoug

Have you checked the grid compatibility between PCBNew and the Footprint editor.
In the past I had some odd issues because of having grids that won't align with each other.

Just my 2 cents...


Best regards
Jorge

DRC agrees that the appropriate pads aren't connected..
Also, when I select various parts of an affected wire it shows as having the correct name at all segments. It really seems correct?
Is there something stupid I'm doing here? Probably...
Any more advice is greatly appreciated.

  As has been said getting the wires to connect is the main part, the
co-ords have to be an exact match for this to happen. magnetic pads
should do the job.

In earlier versions of Kicad there was a weird issue which could end up
with multiple copies of a track or module placed right on top of each
other. This made it almost impossible to select the dud components to get
rid of them, or the correct one to place a wire to. (even when
zooming in as much as possible) These were pretty obvious in the PCB files
as you saw several duplicate lines. Deleting the offending ones solved the
problem.

I've not seen that issue with the newer Kicad i.e. using .pretty files,
but is may be worth a peek in the files just in case.

The problem usually occurred whan a module was accidentally placed twice
rather than once.

Hi Perdo,Thanks, Yes, I'm using the magnetic pads option. It "feels" like the tracks connect properly into place and, indeed, the air-wires usually disappear.
The stubborn ones are a bit more of a mystery. I have completely rewired the connection(s) (several times) to try to get rid of them, but some are tricky.  Once the layout is closer to finished I'll dig in more with DRC to try to figure it out.

  Hi,
Sometimes the track doesn't hit the center of the pad though it seems it
does.
I always work with the "Magnetic pads when creating tracks" option on,
under Preferences->General Settings.
Give it a try.
Regards,
Pedro.

Thanks for the reply Peter.
That's not the problem. I'm familiar with that possible confusion.

One possible problem occurs when you have several connection points in a
straight line - the natural thing to do is to simply place a track over
those points. However, this will leave the intermediate points
unconnected, as far as DRC is concerned. To make DRC understand that
all the points are connected, you must click on each point as you pass
it, so you make a series of track segments, rather than a single
segment, over the series of connection points.

Hello,
I believe I'm making good connections, but am finding a bunch of air
wires won't disappear. Usually they disappear in the usual way.
I'm routing with two layers, using in-line vias, but the problem is also
happening if I stay on a single layer??
Are there any "newbie" mistakes that I might be making? Could there be a
problem with a footprint or something strange? I edited the footprint
for the parts that I'm finding this problem with, b ut only to remove
some heat-dissipation vias that won't be needed. I didn't touch the pads
etc...
Any general air-wire guidelines I should be aware of?
Regards
Doug

[Pedro Martin [e-mail] [kicad-users]]

The problem is inside the footprint U501.

Every pad has 2 pads instead of only one. Edit the footprint and zoom in
on each pad.

There is a smd pad, the normal one.
There is also a tiny pad in the Fpaste layer. As it is in the Fpaste
layer, it is never connected by a track.

Remove the tiny pads nad check every footprint you are using.

Regards,
Pedro.

[Attachment(s) <#TopText> from Doug McKnight included below]
The footprint editor shows the grid to be 50.0 mils when I use "open
from the current board" to edit one of the footprints in question. The
grid is set to 5.0 mils on the board. It seems they should play nice??
Here's the board, in case anyone feels like taking a look. I'd
appreciate any help with this one...
cheers
Doug

Hi
This a bit of a long shot but...
Have you checked the grid compatibility between PCBNew and the Footprint editor.
In the past I had some odd issues because of having grids that won't align with each other.
Just my 2 cents...
Best regards
Jorge

I'm still really struggling with this. I'm not sure what else to
check... Most of my connections are fine, but I've got a few (out of
hundreds) are being stubborn.
I've checked for duplicate footprints, duplicate traces. I've got
magnetic pads on, and the traces seem to align "magnetically" as
expected. I've remade some of these connections completely, to no avail.
DRC agrees that the appropriate pads aren't connected..
Also, when I select various parts of an affected wire it shows as
having the correct name at all segments. It really seems correct?
Is there something stupid I'm doing here? Probably...
Any more advice is greatly appreciated.
Doug

As has been said getting the wires to connect is the main part, the
co-ords have to be an exact match for this to happen. magnetic pads
should do the job.
In earlier versions of Kicad there was a weird issue which could end up
with multiple copies of a track or module placed right on top of each
other. This made it almost impossible to select the dud components to get
rid of them, or the correct one to place a wire to. (even when
zooming in as much as possible) These were pretty obvious in the PCB files
as you saw several duplicate lines. Deleting the offending ones solved the
problem.
I've not seen that issue with the newer Kicad i.e. using .pretty files,
but is may be worth a peek in the files just in case.
The problem usually occurred whan a module was accidentally placed twice
rather than once.

Hi Perdo,Thanks, Yes, I'm using the magnetic pads option. It "feels"

like the tracks connect properly into place and, indeed, the air-wires
usually disappear.

Post by Doug McKnight ***@yahoo.com [kicad-users]
The stubborn ones are a bit more of a mystery. I have completely

rewired the connection(s) (several times) to try to get rid of them,
but some are tricky. Once the layout is closer to finished I'll dig
in more with DRC to try to figure it out.

[Doug McKnight [e-mail] [kicad-users]]

Thanks Pedro! 
So, if I understand correctly, the "magnetic" attraction can attract to either of these "pads", presumably more or less randomly, but if I get the wrong one, it's a problem. 
This explains why the same footprint sometimes appears to work, giving me much confusion...
To me, it seems very very counterintuitive that a track in one layer can be "attracted" to a pad in a different layer. I guess I can imagine that it might be helpful to have "pads" in all sorts of different layers, but the magnetic effect seems so inherently related to connectivity that it feels very very wrong for one layer to attract another.
Am I missing something where it is useful, or is that something that might be worth requesting a behavior change?

This footprint was exported from Ultra Librarian, which is how TI supplies these things. Lesson learned.
Thanks again,Doug

  The problem is inside the footprint U501.

Every pad has 2 pads instead of only one. Edit the footprint and zoom in
on each pad.

There is a smd pad, the normal one.
There is also a tiny pad in the Fpaste layer. As it is in the Fpaste
layer, it is never connected by a track.

Remove the tiny pads nad check every footprint you are using.

Regards,
Pedro.

[Attachment(s) <#TopText> from Doug McKnight included below]
The footprint editor shows the grid to be 50.0 mils when I use "open
from the current board" to edit one of the footprints in question. The
grid is set to 5.0 mils on the board. It seems they should play nice??
Here's the board, in case anyone feels like taking a look. I'd
appreciate any help with this one...
cheers

Hi Doug,

Not exactly.

The track connection is OK. Using magnetic pads avoids the grill issue.

It is the Fpaste layer pad the one not connected. And will be not
connected forever since it cannot be reach from a track.

The pads must belong to an external copper layer, top or bottom for smd,
or both for tht pads.

Regards,
Pedro.

Post by Doug McKnight ***@yahoo.com [kicad-users]
Thanks Pedro!
So, if I understand correctly, the "magnetic" attraction can attract to
either of these "pads", presumably more or less randomly, but if I get
the wrong one, it's a problem.
This explains why the same footprint sometimes appears to work, giving me much confusion...
To me, it seems very very counterintuitive that a track in one layer can
be "attracted" to a pad in a different layer. I guess I can imagine that
it might be helpful to have "pads" in all sorts of different layers, but
the magnetic effect seems so inherently related to connectivity that it
feels very very wrong for one layer to attract another.
Am I missing something where it is useful, or is that something that
might be worth requesting a behavior change?
This footprint was exported from Ultra Librarian, which is how TI
supplies these things. Lesson learned.
Thanks again,
Doug

The problem is inside the footprint U501.
Every pad has 2 pads instead of only one. Edit the footprint and zoom in
on each pad.
There is a smd pad, the normal one.
There is also a tiny pad in the Fpaste layer. As it is in the Fpaste
layer, it is never connected by a track.
Remove the tiny pads nad check every footprint you are using.
Regards,
Pedro.

[Attachment(s) <#TopText> from Doug McKnight included below]
The footprint editor shows the grid to be 50.0 mils when I use "open
from the current board" to edit one of the footprints in question. The
grid is set to 5.0 mils on the board. It seems they should play nice??
Here's the board, in case anyone feels like taking a look. I'd
appreciate any help with this one...
cheers

Hi
This a bit of a long shot but...
Have you checked the grid compatibility between PCBNew and the Footprint editor.
In the past I had some odd issues because of having grids that won't
align with each other.
Just my 2 cents...
Best regards
Jorge

I'm still really struggling with this. I'm not sure what else to
check... Most of my connections are fine, but I've got a few (out of
hundreds) are being stubborn.
I've checked for duplicate footprints, duplicate traces. I've got
magnetic pads on, and the traces seem to align "magnetically" as
expected. I've remade some of these connections completely, to no avail.
DRC agrees that the appropriate pads aren't connected..
Also, when I select various parts of an affected wire it shows as
having the correct name at all segments. It really seems correct?
Is there something stupid I'm doing here? Probably...
Any more advice is greatly appreciated.
Doug

As has been said getting the wires to connect is the main part, the
co-ords have to be an exact match for this to happen. magnetic pads
should do the job.
In earlier versions of Kicad there was a weird issue which could end up
with multiple copies of a track or module placed right on top of each
other. This made it almost impossible to select the dud components to get
rid of them, or the correct one to place a wire to. (even when
zooming in as much as possible) These were pretty obvious in the PCB

files

as you saw several duplicate lines. Deleting the offending ones

solved the

problem.
I've not seen that issue with the newer Kicad i.e. using .pretty files,
but is may be worth a peek in the files just in case.
The problem usually occurred whan a module was accidentally placed twice
rather than once.

Hi Perdo,Thanks, Yes, I'm using the magnetic pads option. It "feels"

like the tracks connect properly into place and, indeed, the air-wires
usually disappear.

Post by Doug McKnight ***@yahoo.com [kicad-users]
The stubborn ones are a bit more of a mystery. I have completely

rewired the connection(s) (several times) to try to get rid of them,
but some are tricky. Once the layout is closer to finished I'll dig
in more with DRC to try to figure it out.

Hi,
Sometimes the track doesn't hit the center of the pad though it

I always work with the "Magnetic pads when creating tracks" option on,
under Preferences->General Settings.
Give it a try.

Thanks for the reply Peter.
That's not the problem. I'm familiar with that possible confusion.

all the points are connected, you must click on each point as you

[Donald H Locker [e-mail] [kicad-users]]

I'm still confused. Why would these extra pads in the F.Paste layer cause traces to fail to connect? Would not the traces be on the F.Cu and B.Cu layers and get attached to the pads on those layers? (I do understand that the extra pads are not correct, but I don't understand how they could cause this problem. And what _should_ be on the Paste layers, if not outlines of the paste?

Donald.

The problem is inside the footprint U501.
Every pad has 2 pads instead of only one. Edit the footprint and zoom in
on each pad.
There is a smd pad, the normal one.
There is also a tiny pad in the Fpaste layer. As it is in the Fpaste
layer, it is never connected by a track.
Remove the tiny pads nad check every footprint you are using.
Regards,
Pedro.

[Attachment(s) <#TopText> from Doug McKnight included below]
The footprint editor shows the grid to be 50.0 mils when I use "open
from the current board" to edit one of the footprints in question. The
grid is set to 5.0 mils on the board. It seems they should play nice??
Here's the board, in case anyone feels like taking a look. I'd
appreciate any help with this one...
cheers

Hi
This a bit of a long shot but...
Have you checked the grid compatibility between PCBNew and the Footprint editor.
In the past I had some odd issues because of having grids that won't
align with each other.
Just my 2 cents...
Best regards
Jorge

I'm still really struggling with this. I'm not sure what else to
check... Most of my connections are fine, but I've got a few (out of
hundreds) are being stubborn.
I've checked for duplicate footprints, duplicate traces. I've got
magnetic pads on, and the traces seem to align "magnetically" as
expected. I've remade some of these connections completely, to no avail.
DRC agrees that the appropriate pads aren't connected..
Also, when I select various parts of an affected wire it shows as
having the correct name at all segments. It really seems correct?
Is there something stupid I'm doing here? Probably...
Any more advice is greatly appreciated.
Doug

As has been said getting the wires to connect is the main part, the
co-ords have to be an exact match for this to happen. magnetic pads
should do the job.
In earlier versions of Kicad there was a weird issue which could end up
with multiple copies of a track or module placed right on top of each
other. This made it almost impossible to select the dud components to get
rid of them, or the correct one to place a wire to. (even when
zooming in as much as possible) These were pretty obvious in the PCB files
as you saw several duplicate lines. Deleting the offending ones solved the
problem.
I've not seen that issue with the newer Kicad i.e. using .pretty files,
but is may be worth a peek in the files just in case.
The problem usually occurred whan a module was accidentally placed twice
rather than once.

Hi Perdo,Thanks, Yes, I'm using the magnetic pads option. It "feels"

like the tracks connect properly into place and, indeed, the air-wires
usually disappear.

Post by Doug McKnight ***@yahoo.com [kicad-users]
The stubborn ones are a bit more of a mystery. I have completely

rewired the connection(s) (several times) to try to get rid of them,
but some are tricky. Once the layout is closer to finished I'll dig
in more with DRC to try to figure it out.

Hi,
Sometimes the track doesn't hit the center of the pad though it

I always work with the "Magnetic pads when creating tracks" option on,
under Preferences->General Settings.
Give it a try.

Thanks for the reply Peter.
That's not the problem. I'm familiar with that possible confusion.

One possible problem occurs when you have several connection

those points. However, this will leave the intermediate points
unconnected, as far as DRC is concerned. To make DRC understand that
all the points are connected, you must click on each point as you pass
it, so you make a series of track segments, rather than a single
segment, over the series of connection points.

Hello,
I believe I'm making good connections, but am finding a bunch of air
wires won't disappear. Usually they disappear in the usual way.
I'm routing with two layers, using in-line vias, but the problem

Bugs happen https://bugs.launchpad.net/kicad/+bug/1664349 https://bugs.launchpad.net/kicad/+bug/1664349 - and sometimes get fixed!

[Pedro Martin [e-mail] [kicad-users]]

The connection for the F.Cu and B.Cu is alright.

On the paste layers there shouldn't be any pad. That causes the problem.
The problem is that the extra pads are not connected.

Somewhere there is a flag saying that there are pads not connected. And
they really are not connected!

So my advice is you should edit the footprint and remove the pads on
F.paste layer. And next time don't use wrong footprints ;-)

Regards,
Pedro.

Post by Donald H Locker ***@comcast.net [kicad-users]
I'm still confused. Why would these extra pads in the F.Paste layer
cause traces to fail to connect? Would not the traces be on the F.Cu and
B.Cu layers and get attached to the pads on those layers? (I do
understand that the extra pads are not correct, but I don't understand
how they could cause this problem. And what _should_ be on the Paste
layers, if not outlines of the paste?

The problem is inside the footprint U501.
Every pad has 2 pads instead of only one. Edit the footprint and zoom in
on each pad.
There is a smd pad, the normal one.
There is also a tiny pad in the Fpaste layer. As it is in the Fpaste
layer, it is never connected by a track.
Remove the tiny pads nad check every footprint you are using.

Pedro.

The footprint editor shows the grid to be 50.0 mils when I use "open
from the current board" to edit one of the footprints in question. The
grid is set to 5.0 mils on the board. It seems they should play nice??
Here's the board, in case anyone feels like taking a look. I'd

Hi
This a bit of a long shot but...
Have you checked the grid compatibility between PCBNew and the Footprint editor.
In the past I had some odd issues because of having grids that won't
align with each other.
Just my 2 cents...
Best regards
Jorge

I'm still really struggling with this. I'm not sure what else to
check... Most of my connections are fine, but I've got a few (out of
hundreds) are being stubborn.
I've checked for duplicate footprints, duplicate traces. I've got
magnetic pads on, and the traces seem to align "magnetically" as
expected. I've remade some of these connections completely, to no

avail.

DRC agrees that the appropriate pads aren't connected..
Also, when I select various parts of an affected wire it shows as
having the correct name at all segments. It really seems correct?
Is there something stupid I'm doing here? Probably...
Any more advice is greatly appreciated.
Doug

As has been said getting the wires to connect is the main part, the
co-ords have to be an exact match for this to happen. magnetic pads
should do the job.
In earlier versions of Kicad there was a weird issue which could end up
with multiple copies of a track or module placed right on top of each
other. This made it almost impossible to select the dud components

to get

rid of them, or the correct one to place a wire to. (even when
zooming in as much as possible) These were pretty obvious in the

PCB files

as you saw several duplicate lines. Deleting the offending ones

solved the

problem.
I've not seen that issue with the newer Kicad i.e. using .pretty files,
but is may be worth a peek in the files just in case.
The problem usually occurred whan a module was accidentally placed

twice

rather than once.

Hi Perdo,Thanks, Yes, I'm using the magnetic pads option. It "feels"

like the tracks connect properly into place and, indeed, the air-wires
usually disappear.

The stubborn ones are a bit more of a mystery. I have completely

As per the link in bcousins post the library is OK, the DRC was broken
again:

"In larger SMD pads it can be necessary to have smaller regions of
paste, so that a larger backdrop copper pad is not fully covered with
paste. It is possible to define "paste only" pads with the same pad
number as the backdrop copper pad."

[Pedro Martin [e-mail] [kicad-users]]

Hi,

As user, I try to help with comments about how things are working in Kicad.

From my point of view, the footprint should not work.

Anyway, I could agree with defining a paste only pad as far as this pad
has no pin number. This way, the pad is not included in the netlist (or
maybe included as non-connected) and the DRC doesn't complain.

I have added this comment to Bug #1664349

Regards,
Pedro.

Post by Dan Kemppainen ***@irtelemetrics.com [kicad-users]
As per the link in bcousins post the library is OK, the DRC was broken
"In larger SMD pads it can be necessary to have smaller regions of
paste, so that a larger backdrop copper pad is not fully covered with
paste. It is possible to define "paste only" pads with the same pad
number as the backdrop copper pad."

Post by Pedro Martin ***@yahoo.es [kicad-users]
The connection for the F.Cu and B.Cu is alright.
On the paste layers there shouldn't be any pad. That causes the problem.
The problem is that the extra pads are not connected.
Somewhere there is a flag saying that there are pads not connected. And
they really are not connected!
So my advice is you should edit the footprint and remove the pads on
F.paste layer. And next time don't use wrong footprints ;-)
Regards,
Pedro.

Post by Donald H Locker ***@comcast.net [kicad-users]
I'm still confused. Why would these extra pads in the F.Paste layer
cause traces to fail to connect? Would not the traces be on the F.Cu and
B.Cu layers and get attached to the pads on those layers? (I do
understand that the extra pads are not correct, but I don't understand
how they could cause this problem. And what _should_ be on the Paste
layers, if not outlines of the paste?

The problem is inside the footprint U501.
Every pad has 2 pads instead of only one. Edit the footprint and zoom in
on each pad.
There is a smd pad, the normal one.
There is also a tiny pad in the Fpaste layer. As it is in the Fpaste
layer, it is never connected by a track.
Remove the tiny pads nad check every footprint you are using.
Regards,
Pedro.

[Attachment(s) <#TopText> from Doug McKnight included below]
The footprint editor shows the grid to be 50.0 mils when I use "open
from the current board" to edit one of the footprints in question. The
grid is set to 5.0 mils on the board. It seems they should play nice??
Here's the board, in case anyone feels like taking a look. I'd
appreciate any help with this one...
cheers

Hi
This a bit of a long shot but...
Have you checked the grid compatibility between PCBNew and the

Footprint

Post by Donald H Locker ***@comcast.net [kicad-users]

editor.
In the past I had some odd issues because of having grids that won't
align with each other.
Just my 2 cents...
Best regards
Jorge

I'm still really struggling with this. I'm not sure what else to
check... Most of my connections are fine, but I've got a few (out of
hundreds) are being stubborn.
I've checked for duplicate footprints, duplicate traces. I've got
magnetic pads on, and the traces seem to align "magnetically" as
expected. I've remade some of these connections completely, to no

avail.

DRC agrees that the appropriate pads aren't connected..
Also, when I select various parts of an affected wire it shows as
having the correct name at all segments. It really seems correct?
Is there something stupid I'm doing here? Probably...
Any more advice is greatly appreciated.
Doug

Post by Donald H Locker ***@comcast.net [kicad-users]

As has been said getting the wires to connect is the main part, the
co-ords have to be an exact match for this to happen. magnetic pads
should do the job.
In earlier versions of Kicad there was a weird issue which could

end up

Post by Donald H Locker ***@comcast.net [kicad-users]

with multiple copies of a track or module placed right on top of each
other. This made it almost impossible to select the dud components

to get

rid of them, or the correct one to place a wire to. (even when
zooming in as much as possible) These were pretty obvious in the

PCB files

as you saw several duplicate lines. Deleting the offending ones

solved the

problem.
I've not seen that issue with the newer Kicad i.e. using .pretty

files,

Post by Donald H Locker ***@comcast.net [kicad-users]

but is may be worth a peek in the files just in case.
The problem usually occurred whan a module was accidentally placed

twice

rather than once.

The stubborn ones are a bit more of a mystery. I have completely

rewired the connection(s) (several times) to try to get rid of them,
but some are tricky. Once the layout is closer to finished I'll dig
in more with DRC to try to figure it out.

I would think that paste-layer pads would be defined as part of the
padstack, and not as separate items.

Post by Pedro Martin ***@yahoo.es [kicad-users]
Hi,
As user, I try to help with comments about how things are working in Kicad.
From my point of view, the footprint should not work.
Anyway, I could agree with defining a paste only pad as far as this pad
has no pin number. This way, the pad is not included in the netlist (or
maybe included as non-connected) and the DRC doesn't complain.
I have added this comment to Bug #1664349
Regards,
Pedro.

Post by Dan Kemppainen ***@irtelemetrics.com [kicad-users]
As per the link in bcousins post the library is OK, the DRC was broken
"In larger SMD pads it can be necessary to have smaller regions of
paste, so that a larger backdrop copper pad is not fully covered with
paste. It is possible to define "paste only" pads with the same pad
number as the backdrop copper pad."

Post by Pedro Martin ***@yahoo.es [kicad-users]
The connection for the F.Cu and B.Cu is alright.
On the paste layers there shouldn't be any pad. That causes the problem.
The problem is that the extra pads are not connected.
Somewhere there is a flag saying that there are pads not connected. And
they really are not connected!
So my advice is you should edit the footprint and remove the pads on
F.paste layer. And next time don't use wrong footprints ;-)
Regards,
Pedro.

Post by Donald H Locker ***@comcast.net [kicad-users]
I'm still confused. Why would these extra pads in the F.Paste layer
cause traces to fail to connect? Would not the traces be on the F.Cu and
B.Cu layers and get attached to the pads on those layers? (I do
understand that the extra pads are not correct, but I don't understand
how they could cause this problem. And what _should_ be on the Paste
layers, if not outlines of the paste?
Donald.

The problem is inside the footprint U501.
Every pad has 2 pads instead of only one. Edit the footprint and zoom in
on each pad.
There is a smd pad, the normal one.
There is also a tiny pad in the Fpaste layer. As it is in the Fpaste
layer, it is never connected by a track.
Remove the tiny pads nad check every footprint you are using.
Regards,
Pedro.

[Attachment(s) <#TopText> from Doug McKnight included below]
The footprint editor shows the grid to be 50.0 mils when I use "open
from the current board" to edit one of the footprints in question. The
grid is set to 5.0 mils on the board. It seems they should play nice??
Here's the board, in case anyone feels like taking a look. I'd
appreciate any help with this one...
cheers

Hi
This a bit of a long shot but...
Have you checked the grid compatibility between PCBNew and the

Footprint

Post by Donald H Locker ***@comcast.net [kicad-users]

editor.
In the past I had some odd issues because of having grids that won't
align with each other.
Just my 2 cents...
Best regards
Jorge

I'm still really struggling with this. I'm not sure what else to
check... Most of my connections are fine, but I've got a few (out of
hundreds) are being stubborn.
I've checked for duplicate footprints, duplicate traces. I've got
magnetic pads on, and the traces seem to align "magnetically" as
expected. I've remade some of these connections completely, to no

avail.

DRC agrees that the appropriate pads aren't connected..
Also, when I select various parts of an affected wire it shows as
having the correct name at all segments. It really seems correct?
Is there something stupid I'm doing here? Probably...
Any more advice is greatly appreciated.
Doug

As has been said getting the wires to connect is the main part, the
co-ords have to be an exact match for this to happen. magnetic pads
should do the job.
In earlier versions of Kicad there was a weird issue which could

end up

Post by Donald H Locker ***@comcast.net [kicad-users]

with multiple copies of a track or module placed right on top of each
other. This made it almost impossible to select the dud components

to get

rid of them, or the correct one to place a wire to. (even when
zooming in as much as possible) These were pretty obvious in the

PCB files

as you saw several duplicate lines. Deleting the offending ones

solved the

problem.
I've not seen that issue with the newer Kicad i.e. using .pretty

files,

Post by Donald H Locker ***@comcast.net [kicad-users]

but is may be worth a peek in the files just in case.
The problem usually occurred whan a module was accidentally placed

twice

rather than once.

Post by Doug McKnight ***@yahoo.com [kicad-users]
The stubborn ones are a bit more of a mystery. I have completely

rewired the connection(s) (several times) to try to get rid of them,
but some are tricky. Once the layout is closer to finished I'll dig
in more with DRC to try to figure it out.

The connection for the F.Cu and B.Cu is alright.
On the paste layers there shouldn't be any pad. That causes the problem.
The problem is that the extra pads are not connected.
Somewhere there is a flag saying that there are pads not connected. And
they really are not connected!
So my advice is you should edit the footprint and remove the pads on
F.paste layer. And next time don't use wrong footprints ;-)
Regards,
Pedro.

Post by Donald H Locker ***@comcast.net [kicad-users]
I'm still confused. Why would these extra pads in the F.Paste layer
cause traces to fail to connect? Would not the traces be on the F.Cu and
B.Cu layers and get attached to the pads on those layers? (I do
understand that the extra pads are not correct, but I don't understand
how they could cause this problem. And what _should_ be on the Paste
layers, if not outlines of the paste?

This happens when there are little “stub” tracks. So there may be a 0.5mm components side “stub” on top of a component side track.





This happens often if using the push and shove router.





Also, a segment may overlap a track without being connected especially if on a pad.





Usually you can find these by asking DRC to list unconnected and going to where the marker is.

One possible problem occurs when you have several connection points in a
straight line - the natural thing to do is to simply place a track over
those points. However, this will leave the intermediate points
unconnected, as far as DRC is concerned. To make DRC understand that
all the points are connected, you must click on each point as you pass
it, so you make a series of track segments, rather than a single
segment, over the series of connection points.

Hello,
I believe I'm making good connections, but am finding a bunch of air
wires won't disappear. Usually they disappear in the usual way.
I'm routing with two layers, using in-line vias, but the problem is also
happening if I stay on a single layer??
Are there any "newbie" mistakes that I might be making? Could there be a
problem with a footprint or something strange? I edited the footprint
for the parts that I'm finding this problem with, b ut only to remove
some heat-dissipation vias that won't be needed. I didn't touch the pads
etc...
Any general air-wire guidelines I should be aware of?
Regards
Doug
