Dear Technos,
we have a customer who recommended 3500 thermoshock cycles -40 to +140°C with 15°C/min gradient. Any ideas/suggestions which PCB material and lead free solder can be used to fulfil this?
As other customers require much less thermo cycles for the same application any hints how to calculate the required thermo cycles out of a mission profile and when the formula for this kind of ALT test does not make any sense (as I think 3500 cycles is normally not reachable for standard PCB material and especially for lead free solder)?
Best thanks in advance,
Torsten
