Hi All;

Interpretation Question;

If I encounter Resin Recession, from 2 oz power planes in Zone B, on a
thermally stressed coupon, what criteria would be applied?

(I only have seen this in one case after 6x thermal stressing (ie 6 dips for 10
sec's), so it meets 6012 now, but it begs the question anyway.)

data:
    hole size:  0.043"drill
    Signal land Size:  0.053"
    Power Plane wt:  2oz
    Power Plane Clearance  diameter   0.086"

location of  recession:  at the internal edge of the 0.086 clearance opening.

Thanks
