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

Some UV cure coatings do not have the correct rheology for sticking to small sharp corners. 984 is one of them. MicroCoat Technologies, Allen, TX makes one that works every time.

Please wash the PCB`s before conformal coating.Do you use deodrant before or after you shower??????

By "they've been through the wash cycle twice" what do you mean? What kind of cleaning process do you use? What sort of chemistry? How do you handle the assemblies after wash and before coating? Do the operators where power free gloves? -Phil

Dave, Few questions concerning your Umiseal 1B73. To cure your Acrylic coating do you respect specification ( 2Hrs-170degree F) or you go faster than that? What do you use to cure it? Do you have to clean your nozzles each day or each monday beca

I use conformal coating DYMAX #984-LVUF and I don't know if it's a problem of viscosity but 0805 components are not covered properly. We use a dispensor to applied it and we cured it by UV. Even if I apply a thicker layer, the coating seems to have

The easy part is to determine which parts should be coated. The harder part is making sure the parts that should not be coated do not get coated. I don't even want to think about the amount of labor and materials I've lost due to conformal coat get

Normally, some conformal coatings do not have very good wetting properties, that should be basic function of a good coating material (the same reqirement as avoid bubbles during coating process)! For UV curing conformal coatings, you can try Lackwe

Outside the MSD issues stated already (and I cannot provide a exact time not knowing multiple factors like Humidity levels, temps, exposure times, etc...) OSP might be the very worst finish to use in this scenario of side 1 / store on a shelf / side
