Fellow TechNetters,
I am desperately search for documents/Publications/Studies on number of
insertion mating contacts will withstand.
Hard gold, Au/Ni/Cu, on PCB fingers is a robust finished. It can with
stand hundreds of insertion cycles. However,
FLASH, Soft Gold, will not be that reliable. Wow about tin lead surfaces.
I know that the thickness/Purity of the
surface plating plays a great part. I really need HELP from the DINOSAURS
out there. I have reviewed IPC-2221.
