I don't understand why you wanna do this. The vendor has done this part for you and actually they have a recommended glue / solder paste life on the stencil or pcb (e.g. 6 hrs, 8 hrs.). If you will stick with their recommendations you won't be lost p

| Hiya, | | Could anyone please suggest recommended manufacturers of | IR rework stations for the removal of various SMT comps. | | Cheers | Why IR ? Ok, I�ve seen only one but that thing burnt the PCB before the solder was melting and costs a lo

Daniele The other repsonses have it right. The junction of the wires measures the temperature. If your poduct needs to be re-used I would suggest either kapton tape or aluminim tape(the better of the two). If this is your "golden board" I would

OK, here is the answers for your questions: - 250 boards every day - We dedross every day at the end of the day - We add approx 50 lbs of solder every day - We use a standard spoon with holes And about Kleenox, is it really toxic? Do we have any al

I read the Cookson/Alpha paper "Optimizing stencil design for Lead-free SMT processing". I interpreted it to mean that if you had a mid chip solder ball (MCSB) problem the "radiused inverted home plate of 20/60/20 style" had the greatest impact on r

We are going to start conformal coating PCB assemblies, and I was wondering about cleaning the boards before coating them. Do I need to clean them and if so, with what? We currently us a no clean solder. I am worried about contamination on the board

I have a customer who's solder paste is drying out on their stencils. Humidity 40-45, Temp 70degrees, no air blowing on stencil, no cleaning stencils with chemicals. Handling of paste is done correctly. I'm thinking maybe the paste froze during shipm

Most of the PTH components are manually inserted. Some are auto-placed by our UIC machine. The parts are preped before install, so there is no need to trim the leads afterwards. The boards go through wave solder. The UIC machine has a clincher on
