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

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

Sign makers utilize a material called "Scotch-Cal" and "Scotch-Brite" in making decals used in outdoor environments. Material similar to this comes in metallic silver and gold. Pieces of this can be economically die-cut and affixed to your PC Board

As said earlier the best way is to cure it then discard. Is your material heat cure or moisture cure? If heat cured and you ahve a oven place the material in trays and heat cure and discard. If moisture cure leave the material in the container and ad

Frank R, I believe the Dymax #984-LVUF is a POLYURETHANE RESIN. I have used Humiseal 1A27 and 1A33 for several years with great success. Both of these materials are High VOC materials. If your customer does not require these materials to be aproved

Well then, maybe it's an incompatibilty between the soldermask and the coating, possibly due to undercuring of the soldermask. Thoughts are: * Some suppliers provide their thoughts on the compatibility of their product with other suppliers. For ins

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

Your problem is likely not the Pd-Ag surface layers, but the underlying metal to which you need to wet. Either a base metal is: * Contaminated and poorly wettable. OR * A material [eg, Alloy 42 (check with magnet), Kovar, etc] that is inherently dif

That is true; it is not a fast process but it is selective and uses minimal material. Also true that the application consistency has to be checked and sometimes minor adjustments made at the beginning of a run. We have a program that checks for a con
