Hi Chris,
Without seeing pics, we are shooting in the dark.
How about some pics?

Subject: [TN] Mech. damage or poor wetting?
We have a BGA dye-n-pry job that shows board side sj damage with a strong
correlation to fan-out clocking.
We also have some microsection evidence of poor wetting.
All damage/dye is on perimeters.
Is this an indication of heat sinking and subpar wetting, or can it be
completely mechanical? Both?
Thanks
Chris
