I am working on an acrylic coating with solid content around 30%, I want to control the coated thickness to be 1 mil exactly. Any experience on this. Best regards.

Does anyone have any experience with underfill of HD connectors? New customer wishes to underfill 6 HD connectors that have been pressed into PCB. Capillary action is causing the conformal coat to wick up into connector. Material is acrylic.

Check with your connector supplier, but most press-fit contacts will pierce through Types UR & XY conformal coat (military approved). Acrylic (AR) Urethane (UR) Epoxy (ER) Silicone (SR) Parylene (XY)

Hey all, we will be starting to coat our PCB's soon. I am looking for info on what type of UV light is needed to inspect the boards. We will be using Humiseal 1B73 Acrylic coating. TIA, JD

A customer of mine is using Chemtronics (Circuit Works) CW3300 Overcoat pen. This is an acrylic conformal coating. It cures at Room temperature. They need something similar that can be UV cured in a pen form. Any suggestions?

Alex, We will be using acrylics only. We are looking for a machine that will allow us to have 20 to 30 keep out areas per PCB. How's your machine at keep out areas? Thank you for any input.

We use 1B73 Acrylic and coat right over an IBM processor which gets a heat sink mounted on top. Never had an issue after 5 years of production. Dont forget to post if you find anything out though.... JD

We just measure the coupon before and after. We are always btw .002" - .003" acrylic. No auditor will say a word if you are doing this much control. Unless its NASA I suppose..... we've never had a problem with any of the avionics guys doing this tho
