| | | Gian | | | | | | You alarm me when you talk of white residues in a "no-clean" process. This should not happen. It sounds like you have compatibility problems between different residues and/or a poorly polymerised solder mask. | | | | | | Ther

| | What oven temperature should be used to reflow solder (Sn63Pb37) on a PC board (0.075" to 0.100" thickness) in 5 to 10 minutes? | | Profiling - tedious but important. As said, start with the paste manufacturers recomendation which is usually pu

| Can anyone give me the virtues of SMT package castellations vs. no castellations with particular reference to the ruggedness and reliability of the solder joints? Any references or studies that you can point me to? Also, although I'm in favor of

We have been encountering diminishing ball shear readings these past few weeks, despite the fact that we did not change any ball shear tester parameter. Our reflow parameters are also within spec limits. ( 210-220 deg C max temp. and 40-60 sec dwell
