We are seeing a rash of pin damage on PLCC sockets. When the IC is 
inserted  the contact is actually bent in half and no longer visible from 
the top of the socket.  We suspect that the change over to RoHS compliant 
parts is a contributing factor. The friction between the two Matte tin 
parts is greater then tin/lead.  The manufacturer suggested trying to 
obtain the ICs with bright tin (good luck with that) but then there is the 
big concern about tin whiskers.  I was wondering if anyone is seeing the 
same conditions and if so are there any suggestions to minimize the 
problem.  Also the supplier is one of the largest connector manufactures 
and they bought up the majority of other electronic component companies.
