Matte Tin finish on sockets | 16 May, 2006

Has anyone had issues with chips not making a reliable connection in sockets with a matte tin finish (RoHS compatible)? We have had issues with these types of sockets. I sent some to the manufacturer, and was told there weren't any problems. We replaced the socket with a non-compliant socket (not matte tin finish) and had not problems. Washing the sockets also seems to eliminate the problem. Any advice?

Need to switch from tin to possibly gold contacts, tin oxidises.
