the board in question is from Foba Laser Engraver, it's a surface contamination coming from.. everywhere, a lot of moving parts that are lubricated. I'm now studding chemicals that we may use for our kind of rework & cleaning. We may think of modifyi

We tried various products years ago to no avail. As you noted, labels either survived reflow or wash, but, rarely, both. We had one that was made out of kapton, and no more than .125" wide that survived more than the others...but, I don't recall an

| Has anyone used the mechanical stencil foil tensioning system from certain company that eliminates using stencil frames and epoxy & mesh? Any comments on whether it's worth looking into? We go through product revisions like we go through clean so
