Hello Hai, The first step is to determine where in the process the bubbles are being generated - either during coating or during curing. You can easily check this by letting a few boards air dry (no oven) and comparing them to the oven-cured ones. I

Hi first DS65 version is a specific dilution for dispensing machine, in this case the typical process is following: application of the conformal coating extraction of solvent (low extraction power is better)2minutes and drying the drying can be done

Hello to all out there, We're considering CC process,and would like to know some defferences between SSC3 of Electrolube and Humiseal 1B73, yes,I know that SSC3 is silicone one,and Humiseal 1B73 is solvent based acrylic as well as other basic propert

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

| | I have boards coated with Humiseal 1B73. At a late point mfg. site we need to remove a series of 0603 resistors for optioning purposes. I have been trying to determine the fastest, easiest way to re-coat the pads after removal. Drying time of the

This material contains acetone in 30% plus range and toluene with this solvent combination ink is not an option. You will have to get a CC that doesn’t contain acetone as solvent.

Having success with Circuit Boards #432 Solvent Resistant Ink - Designed specifically for circuit boards. This medium dry ink is highly resistant to solvents .... It is also non-conducting. Note: this ink contains an aggressive solvent so should not

Tom: Once again - why are you using solvent based conformal coating. 1B31 is OK as a CC but it contains Toluene and MEK!! It is only 35% solids which means you are trying to get rid of 65% solvent. If you must use it due to customers requirement then

Hi sforman1, The chemical that i'm using is a solvent based coating humiseal 1B73. From my understanding,the UV curing is mainly for UV curable coating like the UV40. And the main advantage of using UV curing is for fast throughput and environment
