It wasn't corroding the stencil, it was corroding the cleaning fluid system.

Any materials that come in contact with the flux should be made from stainless steel, titanium, or plastics. These materials will not corrode from OA fluxes. Overspray is an issue. I think Pillerhouse has that jet fluxer, so I don�t think there is mu

A highly activated flux will begin to corrode the imm tin coating after 10 minutes. Corroded tin has poor solderability.

It's amazing. I rarely saw that ENIG finish could be corroded. It should be the Nickel corroded issue and then affected the solderability. Not clear how to clear this, if you get the answer, let me know. good luck

Are you using a SAC305 or high tin alloy? That will corrode the solder tip as well. Chris

Its SAC305 paste. Will that corrode the tip or the tin alloy?

I have found the paste flux is the worst. It leaves a black residue that can corrode.

Depending on the components you are seeing this on, one thing to check would be the solderability of the parts. Sometimes you will find the plating leeches away, and this is a component plating issue. When you solder, the plating actually leeches a

You're correct. We prefer to probe solder, rather than copper, because the solder absorbs the impact of the probe better than copper and so, helps preserve the life of the probe. Beyond that, OSP has a limited "shelf life". If the OSP is not coate

It could be that you're starting with hyper corroded nickel, before you even begin work. With electroless nickel, everybody looks at the nickel, but the cause turns out to be the immersion gold is too aggressive [during fabrication]. Immersion gold
