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

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

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.

I don't know, what you have, but I just got back from the IPC APEX show and I'll make several points: * One take away about 'nano ...' is that it means different things to different people. For instance, in stencil printing: ** DEK uses Aculon and it

I cleaned the stencil with IPA 99% before applying the Rain-X. Apply Rain-X as per instruction.

So far after ~1500 units printed with the stencil treated once with Rain-X, no issues were detected with solder joints. The only difference is no more solder bridges on fine pitch with .010" openings. The print is picture perfect on all pads, nice an

I am not aware of the Nano protek flaking off. However I do believe it can wear off through abrasion. Unforunately there is no red light goes off when it has worn unless you have good paste inspection. Even when it wears it will not take you to a neg

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

Two magic bullets help us greatly with fine pitch printing: 1) nano coatings (we use a DEK product) YES it really does work 2) temperature control in the printer (AC unit). Of course good quality stencil and proper cleaning of the stencil are im
