Daniel,
I don't believe there is any fix for this problem. One Work-around
that 'doesn't' work is to place a fill of the appropriate size and shape
over the pad because when Gerbered the fill also gets drawn instead of
flashed. I have usually found that the draw was with such a small aperture
that it didn't round the corners very much.
How much is yours being rounded, what size is the pad, what size
aperture is used in the drawn Gerber? I would expect the pad is being drawn
with an aperture of 10mil or less, then that is only a 5 mil radius. Is your
engineer being too paranoid, our engineers have never worried about such
minute details even at 35 - 40GHz?
Sincerely,
Brad Velander.
