The three primary causes for bubble generation in solvent-based coatings are: * Air entrapment * Solvent flash-off * Curing the coating too quickly Tell us more about your process including: * When you first notice the bubbles * Extent of the probl

Shadow cure effects are dealt with by post cure mechanisims. New UV Coatings should have one, either heat or moisture cure. Basically UV primary cure starts off cure process, allows handling of the products. But UV is not suitable for all products

Hello, Curious to know if anyone has had some experience converting a Heller reflow oven to Cure 1B73 Coating material. Please share experience and process parameters to help obtain cure to conformal coated boards. TIA!!!

We conformally coat over NC solder paste. No problems. We're using a platinum catalyzed addition cure silicone. The only concern with this conformal coating is cure inhibition. You must test the coating over the residues to be sure there is no in

we encounter bubbles on silicone coating after oven curing.what to do to avoid bubbles?

1) Viscosity measurement of the coating prior to spray, spraying and charting metal coupons for sprayed and cured thickness of the coating at various points of the conformal coat run 2) Yes, manual inspection 3) No, it wasn't able to inspect with t

We use (and have for some time) used No-clean on our radio boards with no problems. We also conformally coat with a platinum catalyzed, addition cure silicone coating with occassional problems. These silicones are prone to cure inhibition or retard

Seeking information on companies that manufacture conformal coating equipment. Pro's and Con's of UV / IR or air cured coatings. Masking verses selected coating systems. Thanks Wayne

What your said looks like a acrylic coating thermal expansion causes small solder joint crack. Do you cure coating with heating, or heating after curing? Solder joint crack while you see resistor and QFN trouble? Clear and detail description of your

Hello Don, We dont heat cure any of our assemblies. We coat relitively few boards and just let them cure at room temp. Perhaps we should start heat curing. In fact, we have an old, fully functional, heller 1500 just sitting in storage. Hmmm. . .
