Subject: [EXT] [TN] Strain or strain rate spec for PCBAs
Hello Technetizens,
Does anyone know of a spec or criteria for acceptable strain or strain rate for a PCBA?
We are using strain gauges to understand how much strain is placed on a PCBA inside one of our products during typical shipping processes.
I know that IPC-TM-650, 2.4.41.2A tells how to measure coefficient of thermal expansion by this method, but I can't find anything about mechanical force, or how much is too much.
Best regards,
