Hi Everyone,

Attached is a picture of a thru-hole corner after thermal stress.  The 
plating is pulse.  I believe the corner was 'burnt' because of the 
geometry of the (conformant) negative etchback.  All the corners show 
burn; some show blisters; only this one cracked.

In your opinion, what are the non-conformance(s) if any?


Thanks

Chris
