How do I spray coat my conformal coating?
Batch spraying is one of the widest used techniques used in low and medium volume conformal coating processing.
Whether you are using a compressed air spray gun or an aerosol can, the conformal coating is sprayed across the whole of the circuit board.
It can produce a high quality coating finish that gives the best protection due to good edge coverage.
However, it is not a selective process. All parts are coated on the circuit board.
Therefore, masking may be required to protect components that must not be coated.
