Good day, What type of solvent are you using for stencil cleaning during production? Does anybody use VIGON SC202 for stencil cleaning? What type of solvent can you recommend? Thank you. BR, Pavel

We currently use Vigon SC-202 in our spray in air system. SC-202 has 830g/l VOC content, so I don't know if that will help reduce your VOC's or not. We used Smart Sonic 440-R in ultrasonic application with great results, but we haven't tried it in

A chemical change is needed to reduce VOC�s in our spray-in-air stencil cleaner. Items that are to be considered to effectively find a replacement chemical that works as well, or better than the current chemical include, but not limited to, the foll

Snap off is the distance from the top of the board to the bottom of the stencil.

SQUEEGEE snap off is the gap between the top of the stencil and the the bottom of the squeegee blades. You can measure it with a set of feeler gauges.

I thought the stencil was flush to the top of the board when Screen printing. When does this snap off occur in the screen printing process?

Hi Adrian, If you do a "squeegee snap off" during solder paste printing...the result would be a very thick solder paste deposition. I think the correct term is stencil snap off or people say it "snap off distance". =)

It is the distance between board and stencil. When your stenciling solder paste you usually want to contact print (which is "0" snapoff). When you are stenciling adhesive you can affect your dot size and quality by using a gap between board and stenc

We have begun using a PCB with Organic Surface Protectant. We normally run boards with non orgainic protectant. We can wash these boards with our ultrasonic cleaner using Zestron SC202 and a separate Hot/cold rinse system with an air knife. This r

Adrian, I'll go again. The term "snap off" on it's own refers to the distance between the bottom of the stencil and the top of the pcb. Sometimes referred to as "print gap". As you prefaced your question with "squeegee snap off" I thought you were as
