Does anyone know of a good masking material for conformal coating? The coating is silicon based. Any help would be greatly appreciated. Thanks

Hi, I've been looking into UV cureable conformal coating and the UV ovens but a chemist I know is very negative about this. He suggest by heating standard conformal coating to 90deg for a couple of minutes will make the product good enough to handle

We have a product that requires labeling and serial numbers that obviousely should be put on prior to conformal coating. 1.What kind of labels/ink/sharpe can be used under conformal coating without disolving etc...? We will be using Techspray 2103-1

I've been tasked with increasing the CCA throughput in our Conformal Coating workcenter. My first approach will be to look into a more *automated* approach for the masking process. We currently use a manual method of using masking tape prior to con

Guys When stripping conformal coating from an entire assembly, how do I know the stripping solution won't damage anything on the PCB ? stuff like electronic sensitive devices, wiring, labelling and plastic hinges. And secondly when conformally coati

We've got a problem here, where we're hand spraying a urethane conformal coat on over a rectangular inductor. The inductor body is a plastic tube, with potting to fill. The top is not always flat (sometimes concave). The problem is that bubbles appea

We've used masking tape and peelable (pink) mask to mask our boards before conformal coating for a long, long time. This is a huge time sink, and increases our lead times (particularly because of the cure time for the pink mask). What are other com

Whether or not conformal coating creates a reliability problem if it bridges the gap between the board and bottom of the part depends on the properties of the coating. A low modulus coating is fine, but one thats modulus increases at colder temperat

Parylene is arguable the best conformal coating there is, unfortunately it's also the most expensive. We had considered using it some time back, but due to environmental and safety issues, we would have had to build a new building to house the proce
