We bought a conformal coating removal machine AKA a sand blaster at an auction. It is a CCR2000 especially made to be ESD safe. Does anyone have any experience with sandblasting conformal coating? We mostly use humiseal 1A33 and UV40. When we use the

PVA and Specialty Coating Systems both have equipment that are easy to program and maintain. It is a spray booth so maintenance needs to be regular or you will have quite the headache. We have a conformal coating line with 2 coaters a board flipper a

We found that a slightly more active flux was all we needed to provide sufficient wetting on the one AgPd part we put down. Unfortunately the paste we tried also slumped terribly, so we nixed that fix. It's a low volume product (50, once every 3 mo

You can pay high-end and just purchase from any big supplier (All-Spec, EIS, etc.) Or you can stop by your local Lowes/HD and find the 15" black-light fluorescent tubes and a cheap desk lamp that will hold them. Put it in a dark room and you are done

There is a 8lb steel plate that is held down by 4 toggle bolts at the top of the machine. Its where you load the cutting media. If that plate does not have a pressure gauge built into it, contact CCR. They will send you one free of charge (at least t

I have used 1A33 for many years with excellent results on through-hole pcbs in equipment subjected to very hot and very cold environments. Because 1A33 continues to harden with time, I assumed it would simply not be usable on smt boards, cracking t

You'd more than likely have repairability issues with the Acrylic based one. The acrylic-based finish is alot harder and more brittle versus the silicone. Some of the new silicones, you can just "peel" with your fingernail, while still getting reli

We are currently storing small amounts of our conformal coating waste. Recently someone asked how we would dispose of the material and I hadn't the slightest idea because this is a new process for us. I started to look into proper disposal for the

I have a product that has earthing/positioning holes, as they are to be used for earthing purposes they need to be free from conformal coating. This pcb is double sided. I have used spot/peelable mask to protect these holes. However when the conforma

Have you considered spraying the coating? Check with the manufacturer of the epoxy to see if they recommend any equipment and whether or not the coating would have to be mixed with solvent to provide a smooth, thin even coat.
