Plasma Finish is an ultrathin fluoropolymer coating applied using a plasma deposition chamber. Reportedly creates a continuous, defect-free film that is just nanometers thick everywhere that the active gas plasma comes into contact with the surface, including high aspect ratio vias. Has stable chemical properties said to greatly extend PCB shelf life, actively repelling water and preventing contact with corrosive gasses. Ensures wettability. Combined with a precleaning step, eliminates activating, plating and rinsing stages in a traditional line. Is completely removed during solder joint formation, resulting in a reliable CuSn intermetallic layer.
