Hi all, We are currently experiencing solderabillty problems with a surface mount header. One of the recommendations from an independent test house was that we specify a gold plated version. My question is; what benefit does gold offer over tin lead plating? (wrt the solder joints) Our pads are plain old HASL. Best regards, Mark Mark Holmes PCB Designer Helvar Merca Ltd.
