Claim of US Patent No. 10,485,108

1. A method of providing an amorphous fluorinated polymer conformal coating to at least one side of an RF circuit board, the method comprising:providing a coating solution including the amorphous fluorinated polymer dissolved in a fluorinated solvent;
applying the coating solution to the RF circuit board via a mechanically controlled fluid spray application device to produce a coated board; and
waiting a predetermined time period to substantially evaporate the fluorinated solvent from the coated board, thus leaving behind a conformal coating of the amorphous fluorinated polymer on a board surface area.
