How do I spray PCBs with coating without ruining the ESD board I am spraying onto and meeting ESD requirements?
There are several ways and no ideal solution. Basically, you can spray onto boards that are covered in paper or ESD bag material which will then earth to the turntable of the booth. Since the operator should be earthed via the ESD points or the floor then you creating good protection for the device.
However, it is important to change the material regularly since a build up of coating turns the material to an insulator fairly quickly!
