Hi Eric,

What is it you like to qualify for? Is it just process yield, you simply will
have to run an adequate sample through your processes. There is no IPC spec
for this.
Do you want to assure reliability, than there is IPC-SM-785; but before I
would embark into expensive and time-consuming accelerated reliability
testing, I would look hard at IPC-D-279, Appendix A.
