Assuming that you have a saturated moisture-sensitive component: At what temperature would popcorning or internal component damage occur? I would guess that it would be at a temperature where water would boil, around 100 degrees? However, the JEDEC J

Wondering how you guys do this. Scenario: You have to rework a part (small IC or resistor) on a board that has already been conformal coated with acrylic. What do you do with the post soldering residues before you cover it up with fresh coating?

I've been using Xilinx TQFP's in the 44 and 144 lead sizes with no trouble. I don't even bake them before reflow and have never had any problem. The Xilinx parts are certainly NOT sensitive, I could not break one with my bare hands if I tried (I ha

Can someone please advise me to the rework procedure for removal and replacing Ceramic Chip Capacitors (e.g. 0805, 1206, etc.)? Is it necessary to pre-heat ceramic capacitors before soldering them onto a PCB with a soldering iron? Is this just a rec
