If you are looking to rework (after all of the previous suggestions are taken and tried....you have some solid ones in there). When a device like this is placed and is hard to get to we use the 7721 bumping process using a controlled heat source (no

UPDATE The reason for the board count in the wave when there are no boards is due to operators leaving racks with empty PCB slots. The input feed sensor is a little bit more in the center of the conveyor whereas the output feed is a slightly closer t

If you have soldered with HASL finish then the worrying chemistry will be more like NON IONIC. They sit there and attract moisture like mad and any chlorides they hold ionize in the moisture attracted and cause electromigration or SIR issues. They ca

If the board is just not reaching the temps you need, you could place them in an oven to "preheat" them. When I was building a rather thick board with a copper core I had to do this. Since we were only doing small runs it was feasible, I don't know y

Hi Folks, It's been a coon's age since I've been on here. I'm wondering if the community can't help me out with something. "Back in the day" there were thermocouples made by Saunders, Temprobes, with a design that would clamp on the board edge. Yo
