Hi Steve, Make sure your spray head is all the way down. If so, try slowing your rate of speed over the part. Which head are you using to coat this part?

We don't coat anything in a socket or any test points or connectors, switches, leds, wire holes, grounding pads good luck

If the operator has zero charge and the board has a 10kv charge, when the operator pulls the shorting strip from the edge connector after the coating has cured, there is a large potential for ESD induced damage.

Asymtek in-line machine with the Jet head hands-down. And since you will be coating silicone you should virtually have no touch-up after it exits the machine because of the higher viscosity of this material.

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?

Thanks for the reply. I didnt consider this too peculiar a situation however, since pretty much anyone who coats boards with a thin material like acrylic prob has come across this. Maybe its time to invest in some machine upgrades! Thanks

Once you dip it in liquid, the make-up of the brush does not really matter as it is now coated. A dry brush is a different story.

The US military no longer approves repair processes. What coating material are you aiming to remove? Choices for stripping are: * Chemical solvents * Heat * Media
