I would recommend some sort of saponifier that has been tested and is known to remove the no clean flux residues that you're trying to remove.

On the printer alcohol always worked way better than water. If you talk about after job is done, most stencil cleaners work with some solution/saponifier and DI water.

I've read some articles like https://www.apogeeweb.net/electron/what-is-a-shunt-resistor.html, but I still have no idea.

Hi SMTnet. It is possible to reflow BGA's 0.65 pitch with a convection oven that only have heating zones on one side (topside) or is it a must to have heating zones on both sides in the oven (top and botton). Regards Ole C. Denmark

Sorry, I attached the wrong file. EXM settings are explained in this one. No need for installation discs.

What is the proper storage and shelf life after washing a PCB with an OSP finish? We sometimes have to pull the boards off the line and wash the solder paste off the boards.

"We sometimes have to pull the boards off the line and wash the solder paste off the boards." Unfortunately I can't answer your question with any authority, but I guess my question in return would be why? Can you do something to address t

The best shelf life for OSP is run both sides the same day they are opened for the first time. They are good for JIT but I didn't know that they were still good after washing.

OSP is there to keep the copper from oxidizing. Once you wash the board, the copper is exposed. So, you have to either use it right away, or store it in a non-oxygen environment (vacuum/nitrogen).

Does anybody have experience with ATF's selective soldering machines? Information on the web is scarce and their responses to my queries are either none or very limited. Any information is welcome...
