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.
