We ran a batch of boards that had surface mount PLCC84pin sockets.  PLCC
components are placed prior to shippment.  Our customer have noticed that
few boards had disconnected socket pins(one per socket).  Only thing that I
could think of that would cause this to happen is, installation of PLCCs
into its socket, creating enough  shear force on the connector to break the
solder joint.  I didn't get a chance to look at the broken solder joint
itself, but I took a look at some of the finished goods in house, and the
plastic housing on the sockets bow out a little bit upon insertion of PLCC.
 Has anyone seen this before?  What else might cause this to happen.
Customer had stated that the solder joints are well wetted.  Any input is
greatly appreciated.
