We clean some of our boards because we are in the medical and military industries.

What paste are you cleaning from the board?

Hi, I would also be interested in this thread, but our problem has a different twist to it. We have good results from our reflow with Koki no clean paste, however when we pass the boards through the wave solder machine, the flux in that leaves a fog

Used a Gen 3 system for screens & boards. TDC for inline washing.

80ppm). The CTE of your board and solder joints will typically be 18-22ppm. We have seen cases were the coating fills the gap between the component and the board, then during temperature cycling the coating expands to the point of breaking the solder

We are also having the same problem here. I was told earlier that it could be a problem with the solder mask during the raw board manufacturing level but then I noticed that the problem was only surfacing on boards that went through the wave. As far

Hi, Thanks for the ideas. With the solder mask curing problems, can you normally wipe off the white residue, as we can do this on our boards with our fingers. It's almost like the surface of the board has a "wet dried up" look to it, and it's a smok
