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
