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

Yes, car rims (and brass tubas)! You finally helped me get to the bottom of this expensive issue. We fired the culprit. It's the same guy that was using the ultrasonic stencil washer to clean car parts on night shift. It might be snake oil, I don

Thanks, all, for your responses. It's always helpful to know what everyone else is doing, whether to validate your own experience or to force you think in more detail. At this point we've determined that no amount of aperture design, material contr

Good morning, I can recommend to use solder paste softeners, which can prepare solder paste for printing process. Softeners rise paste temperature by means of pseudo-planetary motion. Therefore, solder paste reaches room temperature during only 15

As per Travis's reply it could be something other than the reflow process. Another good one is if the printed PCB's have been cleaned down due to print misregistration etc.. If not properly controlled paste residues can remain distributed about the p

It is sort of a self answering question if you come in from the solder paste angle. First....start gathering data. Check every day, or every new paste jar, for: Storage conditions (temp), paste expiration date, ambient temp and humidity where yo
