There is too much variation in the different Conformal Coating types and application requirements that you will get many different answers. Your controls will be tailored to the job requirements. My controls for parylene coating aerospace product is

Hi, I have a PVA conformal coating machine. Does anyone out there have a method to control the process once it is in the automated mode? my problem is that eventually the coating gets into the keep out areas a little bit and causes issues. is anyone

For boards that would need the conformal coating process, you would need to have them as clean as possible; especially the no clean process

10kv on the surface of the board. To avoid this charge: * Use an electric paint sprayer to apply liquid -base conformal coating * Purchase a metal nozzle for an electric spray gun so that it can be connected to ground * Use a nuclear ionizer where th

It depends on what material you used, but normally viscosity, adhesion, thickness and coverage is usually being inspected in production.

Currently experiencing a problem where the plastic molded bodies of tantalum capacitors are cracking during my SMT processing. Caught after our conformal coating process. I don't know where in the process they cracked. Currently running an exper

Hi! We have both Dip & Spray conformal coating processes & have never done any kind of baking before the process! I am assuming the reason for baking would be the same - ie, remove any moisture on the brds since moisture will create failure of the co

I will be starting a conformal coating process soon, I am looking for any pointers on 1) Best method for masking components, tape mask, liqued mask 2) Which is best Spray or Dip? 3) Compatiblity with no clean solder paste (flux residue) I have Mil

John, I have had previous experience of immersion silver coated PCB's in place of HASL coated type using no-clean processing with little or no problem at all. All of the process parameters were left unchanged. There is a very minor difference in th
