Shift vias away from CC3000 pads #24

Closed zsup closed 10 years ago

zsup commented 11 years ago

Advice from Bunnie: we should try and keep vias away from pads (to prevent solder splattering into them and creating shorts)

This of course conflicts with our effort to have GND vias near the GND pins, but perhaps there may be opportunities for small fixes here? @satishgn, what do you think?

Distinguish between vias and pads on the same net,

Different nets are the problem.

As suggested elsewhere - try increasing the pad-via clearance and re-running DRC to see what drops out.

GND vias okay near GND pins. Just pads of different nets need to be put away from in particular the big fatty ground fills right in the center underneath the CC3000.

Shifted the GND via away from the CC3000 pad.

Did just a little bit more shifting. We're a bit constrained so it's hard to shift too much, but it's a bit better at least. Closing this issue.
