Hege, the Nano coating goes on the opposite of the squeegee side of the stencil. I don't know if the cleaning paper is able to remove it little by little with the time, but I never refreshed my stencils with Nano coating and they work just fine. How

Has anybody else tried using stencils coated with Nano ProTek? I did find that I could reduce my cleaning frequency and squeegee pressure, which should help to increase stencil life, but I'm finding that it seems to wear off quicker than I thought i

I would be careful with trying Rain-X. Rain-X is a silanol treatment that is not durable. That is why you need to reapply it on a windshield many times. Also you could contaminate the paste as it will come off the stencil during the printing. From

IMO – Look into nano-coatings for your stencil and radius all square apertures This should help out with solder paste releasing from the stencil helping with insufficient solder QFN LGA aperture design, try a stencil cut with a few different apertur

But where does it go, that it needs to be refreshed or replenished on the stencil? Does that "just like wax" product wind up in my solder joints, no matter how small the percentage, and would it then qualify as a contaminant? I heard there are some (

I do not know of a way to measure the nano-coating. However, it is easy to check if it is still on the stencil. Simply use a 'sharpe' pen and try and mark the bottom (PCB) side near any openings. If it easily marks, then the nano is no longer present

We chose the MPM over the DEK. We did real world comparison in our factory with both machines almost side by side last year. MPMs offer a real windows based software that basically takes the operator out of the equation. Besides the basic screen p

It's actually a "silane" according to the same article. Also, it "bonds" with the surface of the stencil. once bonded, it's not going anywhere. I'm not a chemist. I'm not promoting this product to be used on stencil. I'm just pointing out that what i

Nowadays I cut everything with nano-coat. it does improve release and adds 25% to the stencil price. Adds a little more time to cure the coat.

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.
