gEDA-user: Interesting board defect

[Eric Brombaugh <ebrombaugh1@xxxxxxx>]

FYI:

I just got a couple of new boards back from BatchPCB and found that one 
of my power supplies was shorted to ground. A close inspection revealed 
numerous hairline traces from the pads of some SMT capacitors which had 
been placed in a surrounding ground plane. A photo is available here:

Looks like just a tad more clearance around those pads would have 
prevented those fine traces of ground plane from forming, floating free 
and shorting to the supply pad. I can probably get out the x-acto and 
scrape these away but it'll be tedious.

Learn something new every day...

Eric
