The equipment of Specialty Coating Systems and PVA is both simple to operate and maintain. Since it's a spray booth, constant maintenance is required or you risk having a serious headache. Our conformal coating line includes a double-sided UV oven, a

The short answer is immediately after reflow the problem occurs. To be more exact, what you are describing is not "rust". Rust occurs in iron. The oxidation that occurs in Tin-Lead has been sometimes called "white rust". Either way, oxidation occur

We have draft/vent booths for our folks, we had a local company here make them for us with Black lights built in. they work nicely there is a constant draw. We also had the same company build drying cabinets, they have constant draw/ventilation on th

How does the cost of these machines compare to setting up a spray booth? The large outsource coating houses around here all spray from a gun in a booth instead of using machines. Is there a breakpoint in volume where the machines make more sense?

Does anyone do this? We have a small booth and lots of different kinds of media to try. it will be local stripping of coating on components for rework purposes. My main concern is ESD levels and how best to measure this. Any ideas or any papers o

Yeh due to the solvents in the coatings im guessing there is a health and safety risk. Solvent stripping is a lengthy process for the coatings we use and usually means submerging the whole board so not local to the rework. We have a booth with ioni

Tony, Conformal coating will protect the board from outside moisture but will also encapsulate Ionics and moisture when present on the board.
