| I am wave soldering a single sided through hole PCB array with (6) .040" round diameter pins that sit .5" off the PCB, and .080" apart. The problem being experienced is that solderballs are appearing on the end of the pins. I have tried decreasin

Yes, unfortunately a lot of datasheets these days do not contain the temperature resistance to determine if it can handle the PIP application. In the past I have always used a 250 C at a min of 5 sec for the material. Also, the part should have sta

| Are there many of you who are soldering through hole parts in your surface mount reflow oven? How repeatable is the process? Do you need to touch up a lot after reflow? We don't do long runs maybe 200, 300 boards max. Can you just screen print

You're correct that a thicker solder deposit will make bridging on fine pitch devices a bigger risk. Another alternative could be to slightly over-print the pads (onto the soldermask) ala pin-in-paste process. Basically adding enough solder to fill

Chris, I don't know what machine your using, but we're also playing with one at the moment and don't see any problems with micro solderballing as far as I'm aware (I'll double check tomorrow thou!) We're using Kester 977 with it and don't have a pro
