Hello TechNet:
We are searching for a method of accelerated aging of PCBs with surface finish in white tin (chemical tin).
This method should be recognized , in order to simulate the storage of 6 or 12 month under normal conditions.
(85/85/1d or 2d test ??)
After such an accelerated test, the solderability will be tested by the wetting balance method.
Thank you for your answer
With best regards
Peter Hefti
