SpletTin plating is a metal finish deposited by a chemical movement reaction applied directly to the copper on the board. This older technique has undergone some changes over the past few years and the finish performances have been improved. The reference standard is IPC-4554 Specification for Immersion Tin Plating for PCBs. SpletPoor solderability of the pins can be caused by poor or thin plating or long storage times. Solderability of tin/lead pins normally is a function of the plating thickness or of the plating and the base materials. In the case of brass pins, the pin must first be plated with a 1-3µm layer of copper before the tin/lead is applied; otherwise zinc ...
