I have soldered several 5*5 QFN32 ICs( with exposed pad) manually with my old hakko 5880. I checked them all be ok immediately after soldering. But after some minutes or some days, I found them all failed with different errors. I resolderred them and checked OK. But failed again after sometime. I did it round and round and it really drive me crazy. Could someone help me out?
