Does anybody have any idea if there is a specified rentention time for PWB (printed wiring board) test coupons?
1) Does anybody actually keep them?
2) Do you deliver them to your customer instead?
3) Do you end up disposing of them?
4) Do you keep them forever (so far)?
I did some digging into this and I've found nothing except IPC test patterns for coupons and the old Mil-55110 requirement.
Any input on this matter would be appreciated.
