Excessive mask thickness also can wreak havoc on stencil printing.

Several methods work well. 1. (Low Volume Method) Using an Xacto blade, scrape off the solder mask holding the blade flush being careful not to use the pointed part of the blade. 2. (High Volume Method)Tape off the area that you don't want the mas

One of the DFM suggestions I've seen is to remove the solder mask web, i.e. the mask between pads on 20-mil QFP devices. The rational is that if the mask is thicker than the pad the mask can prevent the stencil from making intimate contact with the

Would advice to mask only for trial. Cut the proper stencils is the solution.

I typically use kapton tape when I need to mask off some apertures.

Hi there, I'm pretty new to the SMT manufacturing stuff, please be kind. I have to mask up some parts of a stencil. Is there a recommendation for some masking tape I could use? It should be sticky enough for temporary use but not that sticky that i

Steve i agree with u. we use kapton tapes for test puproses at our facility and they do not interfere with the printing results. Infact we sometimes use it to mask off unwanted apertures on stencil underside. But could their applcation affect the gol

Kapton works great, but note that Kapton is about 2.5 mils thick, so if you are placing it near other apertures, you are essentially adding to the thickness of your stencil. I've also used some Kapton near parts that need a bit more paste, like co
