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.
