Abstract
A method of, and system for, providing an amorphous fluorinated polymer conformal coating to an RF circuit board is described. A coating solution including the amorphous fluorinated polymer dissolved in a fluorinated solvent is provided. The coating solution is applied to the RF circuit board via a mechanically controlled fluid spray application device to produce a coated board. A predetermined time period is waited for substantial evaporation of the fluorinated solvent from the coated board, thus leaving behind a conformal coating of the amorphous fluorinated polymer on a board surface area.
Claims6
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.
