Has anyone had success using a DEK Proflow printhead with fine pitch components (~.2mm pitch). I have been told that squeegees are the way to go for fine pitch. What other major factors play a role in successfully printing fine pitch. Print speed,

Thanks for the replies. I have just ordered the IPC Stencil Design Guidelines manual.

Nano coating = Rain-X = Snake oil

Yes, I agree with Evtimov. It's more about aperature reduction and type than it is the type of machine. Aspect and and Area Ratio are very important. Take a look at this page I found on the internet http://www.qualiecocircuits.co.nz/stencil-techno

I heard it works well on Chrome Rims for your car too. Swag, I'm not at all suggesting that your operators have discovered this and this is why you keep running out and have to keep ordering it :-p

I've used the Nano Protek product in the past and it is fantastic, worth every penny for those small aperatures. It's just like a wax and yes it works great on rims ;)

I believe it's mostly worn off through cleaning solvents and the slight abrasion during the under stencil cleaning process. I couldn't say whether or not it's ever in a state that would allow it to transfer to the PCB though.

See if you can get a sample of Dek's Nano Protek. We use it on all our fine pitch stencils. I'd say it's kind of like car wax for the aperture walls. They operators really like it a bug me every day to order more if we run out.

Hey SWAG, any idea where that Nano Protek goes, that you have to replace it? (and I am not talking about polishing up wheels) Is it being scrubbed off of the stencil during the print process, and over time it must be replenished? Sorry a bit off top

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
