Can anyone share some good practices to reduce FOD in the conformal coat area? I am new and trying to get my hands around a serious FOD issue. We get red, black, blue, and white fibers that gets trapped in our conformal coat, causing a lot of scoping and touch up. I think some of that is our gloves. Are their any gowning practices, environmental controls, personnel requirements, etc that can be used to reduce FOD?
Hi, Use nitrile or latex gloves for handling your product from your pre-coating cleaning step onward. In my opinion, conformal coating should be isolated from the rest of the factory floor. I'm not saying you need a clean room or even a white room. You simply need an environment where you can keep your particle count in check via vacuuming with a hepa vacuum and dusting. Regards, justin
