Concur with Richard,

good document, professional and academic. But if I am not mistakening, it does not mention real failures from voiding.

BTW, your experience is very well appreciated, extreme conditions, bad voids. I am wondering if regular testing, like HALT and the others caused joints to fail due to voiding.

What about failures due to chemistries, WS flux entrapped into voids that corrode their way out?

Best regards,
Ioan
