I have been told that stencil nano-coatings are rain-x in a different container. I guess I half believed it until I opened up a sample the other day. It smells EXCACTLY like rain-x. For those of you that have never smelled rain-x it has a very distin

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

I believe that Rain-X contains silicone and Nano-ProTek solution does not. I did speak with a field service guy for Nano-Protek and he told me the special coating test pen that they offer is just a sharpie with their logo on it. Thats how I test to

I was at an SMTA meeting Friday. One of the topics of discussion was nano coatings. 1. Nobody wants to talk about where the coating goes as it wears off. 2. There are different types of nano coatings : Chemically bonded which involves a special bon
