Abstract

The invention discloses a preparation method of an FPC die-cutting antenna. The method comprises the following steps of S1, obtaining a copper foil, and plating a metal layer on the copper foil; S2, forming an antenna circuit on the copper foil through die cutting; S3, pasting a PET film to the face, not plated with the metal layer, of the copper foil obtained after die cutting to obtain an FPC; and S4, carrying out die cutting on the FPC obtained in the step S3 according to the shape of the antenna to obtain the FPC die-cut antenna. After the antenna circuit is formed on the copper foil by adopting a die cutting process, the copper foil and a PET film are laminated to obtain the FPC, and the die-cutting is carried out on the FPC according to the shape of the antenna to obtain the finishedproduct antenna, so that the operation is simple and convenient. According to the method, a large number of antenna circuits can be formed on the copper foil at a time and then are segmented, so thatthe production efficiency is greatly improved, meanwhile, the raw material waste and environmental pollution caused by using chemical reagents are avoided, and the production cost and the defective product rate are effectively reduced.
