Yes, 0.25x0.25 square could work @0.1 thickness, use nano-coating or electroform stencil for better solder paste release.

Did you try 0.12 or 0.1mm nano coated stencil @ 10 mil aperture? A soak time type profile with long reflow time could help.

Hello, do you perform any stencil maintenance? What type of controls do you use? Also interested if you have a way to measure nano coating thickness? Any ideas will be appreciated.

I received the weekly email from "EXPRESS" SMTNET Every link (on Nano coating) says "403 Forbidden, you do not have permission to view this resource"

Just for the sake of passing along the information, the fine grained stencil provided zero improvement over the standard PhD stainless and was not nearly as helpful as the baked-on nano-coating. We probably won't be trying that again unless we go und

Nice idea on the rain-x. I'll give it a try, thanks.

Yes, the smaller the aperture, the more difference you will see. It's at it's best on the very fine pitch(

I agree with SWAG on this. Nano Coatings make a big difference on paste release. I found when placed on the topside of the stencil, it also helps to reduce stencil wear, though others complained that it affected the solder roll, so most stencil house

In my experience there is no need for wet wiping stencils. We run 0201'and micro BGA's daily with no issues. If you are having paste release issues, I would be looking at other things. Aperture area aspect ratio, aperture design, land design, sold
