Learn MoreFilm Capacitor principle. The film is processed to allow metal atoms to attach to the film. The metal is evaporated under vacuum (1200 ° C for aluminum) to the surface of the treated film (the film is cooled to -25 ° C to -35 ° C) to form a metal layer. If the dielectric is short-circuited, the metal plating will volatilize and short-circuit.
