Hi,

For the invisible nano coating, do we have any rapid method to determine nano coating worn out on stencil.

Hi,

Some nano coat supplier said that you can drop water to the surface where the coating supposed to present before to check. If it's beading, it's still there. I take it that you meant by self in-house wiping of coating, yes?

Stencil supplier nano coated stencil usually includes some light color dye to determine the coating presence, in which, if the color is faded then the coating is most likely gone on that areas as well.

What sort of nano coating? The coatings that aren't snake oil tend to have a color to it. The other ones are typically wipe on and seem like a waste of time to me.

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 there.

Steve I did investigate the transparent nano coat before for performance. We examined 3 different assemblies based in design criteria. In more simplistic designs it is not worth having it. On more challenging designs it is worth. It proved to have better release with 10-15%. Now I order all with Nano Slic gold - it is there and you can tell as it is in color.
