Lyon, plastic blistering in a DIMM connector caused by solder process can be
attributed to several possible causes including a housing material that is
hygroscopic so may have absorbed excess moisture, it could be material with
inadequate high temp resistance, improper molding, to name a few. What type
of spec would you expect to see from IPC? JEDEC controls the DIMM modules
and connector performance.
