We have PVA 350 benchtop dispensing equipement with humiseal 1A33 CC material. is there any moisture measurement process in conformal coating material?

Could be as simple as a pail full of UR coating and some wire hangars! Conformal coating is brushed on, sprayed on, and parts are dipped too, not to mention the wonderful vacuum process that is paralene. Gotta have a little more info as to your a

We are looking to puchase a table top conformal coating system. Can anyone tell me what to look for and are there systems that wont brake the bank.

If I am not mistaken you can buy Spray cans of Conformal Coating. For the small batch in the environment you are describing, that might be the ticket. A bit pricey material wise, but clean up is a cinch. A little masking tape, and spray away!

If you are going to coat very low volumes then just spray it by hand. The automated machines just won't be worth it unless you are going to do a very large run. They are complicated, require constant attention, still require masking the board and are

Our production runs normally are 20 piece builds. We don't what to brush because of the brush marks left behind. Reason we wanted a machine is more control then dipping with a tub and modified paper clips. The other problem we have is the company as

For that low a volume it would be simplest and most economical to just out source the work. If you want, just send me an e-mail and I can give you specific options on what would be best for you., in-house or out-house.

Davef, thanks for inputs. I think your correct, we have since obtained some ionic analysis and sure enough there is relatively high chlorides on the bare pcbs. The toluene is controlled within dip tank / drying system, almost no exposure to workers.

Why in heavens name are you using a heat or air cure conformal coating. Why aren't you using a 100% solids UV cure system. You would never have an issue like this Sam Forman MicroCoat Technologies
