Most esteemed colleagues:
With all your help over the past 24 hours, I thought I had this figured out
and was ready to move on. However, upon zooming out so the entire board
filled my screen, I became aware of a distinct diagonal line in the fill
pattern on the B.CU layer. I have a screen-shot below showing this
phenomenon, which is a bit more pronounced with the F.Cu layer hidden. The
line seems to go from the upper left to the lower right, and, looking
closely where the copper fill ends at the line, there are several places
where one has ask - why didn't it fill here? And why are the ends of the
fill forming such a uniform pattern? My board layout is not at all like the
pattern I see here. Unless I still have a setting wrong, this seems to
point to an odd idiosyncrasy in the copper fill algorithms.
Further, zooming in sufficiently along this line, I see yet another odd
artifact. Where the copper fill does not stop improperly, there is what
appears to me to be a hairline crack in the copper pour:
Add we can see how that strange crack goes the whole way to the corner of
the board:
Does anyone have any clues to these oddities? Gee, I hope it's something
stupid I'm doing.
I'm a bit nervous sending this out for fab without at least some sort of
plausible explanation, if not a fix that corrects the odd hairline and the
copper pour terminations along the line.
Thanks for all your help!
