Sorry fellas -disagree. We only clean our stencils in the ultrasonic machine at the end of the run. If the same pcb is up the next day we clean them by hand. We use Electrolube SSS and the used rolls from the in line under stencil cleaner. Wipe the

I think you are right. According to IPC-7526 section 6.2 says that using compressed air to blow out paste will damage the stencil, especially between fine pitch apertures. It can also broadcast solder paste onto other surfaces or personnel. I recomm

It would depend on the solder paste but the stuff we use is heavy enough that it wont go airborne. and theres really no other way to clean the apertures on a 0402 or similar part.

I was using a combination of Alcohol and then compressed air for a while because I didn't wanted to add new hazardous chemicals into my factory but after looking into Vigon SC200 with a H/F/R of 0 I decided to try it. Since I started to use it, my

If you have Flexhead nozzles you need to be careful that whatever solvent you use does not attack the gasket adhesive. I might try a couple of drops of a spray like WD-40 or LPS. Let it soak for a few minutes and blow it out with compressed air. Repe

When we get a bad print at SMT, the operator uses the alcohol wipes and wipes the paste off the board. Then they use compressed air and another wipe. In most cases this is sufficient. Most vias are tented, but there still remains some solder sphere
