Rain X goes on windshields. Nano coating goes in the garbage. Order your stencils correctly from a reputable stencil house and fugetaboutit.

I'm wondering if anyone has ever done a before/after test on the wipe-on type to see if it's any better. The factory applied stuff has been a game changer for us and as already stated, has the added benefit of a dye to indicate that it's still ther

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

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 (

The paste is going to roll as before because you have to apply the coating on the bottom side of the stencil. Also the coating that wears out will most probably go to your stencil cleaning paper as that the process wehn you actually have friction wit

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 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

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.

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
