We are producing boards with Alpha 591S RMA No-Clean paste and are coating after SMC with Dow silicone ( toluene solvent based) conformal coating. We have experienced several failures due to soft shorts ( electrochemical migration?) We have also obse

I haven't used this particular CC, but...found this in their data sheet: "AVR 80 BA Conformal Coating will be touch dry after 15 - 20 minutes at room temperature and does not require a thermal cure. The full properties of the coating will be obtaine

We are in the process of validating Silicon 1C55 (thermal cure) conformal coating over Alpha LR725 solder paste. I am looking for anyone who may be using this process, or has been exposed to someone who is doing this process. Our concern is with the

Hi Guys, I have few question would like to ask regarding pcb conformal coating: 1. Can I know which masking material is the best for easy apply, fast cure, fast & easy to remove after coating & baking. And no chemical reaction which will whiten the

Hi All; Anybody here have experience in AVR80 BA DS65 CC process? I have an issue with the curing process at 28 degC RT. Can somebody recommend how to accelarate the curing without IR oven? thanks

Hey Jack: It's certainly "do-able." Conformal coating adhesion testing was done as part of the "Evaluation of Low Residue Soldering for Military and Commercial Applications: A Report from the Low Residue Soldering Task Force," published by Sandia Na

Steve, We use that Circuit Works pen as well! You can purchase a UV cure then download it to an opaque syringe or bottle. Use a small EFD or similar luer lock tip and dispense where needed. Tom

We: * Cure 1B73 according to spec in a heat box, like a Blue-M * Clean nozzles [one set in use, one set being cleaned] in thinner in a bronson ultrasonic cleaner * Haven't evaluated coatings in years, but would do it according to J-STD-001C, Reqmnts

Good morning. We have a used Nordson Coater, Batch type (not pass thru), w/o cure oven,that you can purchase for $9,950.00. Unit has been cleaned and lines purged. It was running when decommissioned, and is still in nice shape. Thanks, Nick Haviland.

Does anybody run conformal coating process using UV cure varnish? We have a long experience on solvented urethane coating material but switching to solventless is unknown for us. Could you recommand vendors for UV curing oven? Thanks
