Abstract

The invention relates to a technological method used for printing a mobile phone antenna. The technological method comprises following steps: (1) PIN needles are printed with an ink with high adhesive force; (2) the PIN needles are dried at a temperature of 60 to 200 DEG C; (3) the PIN needles, which are printed with the ink and obtained in step (2), are inserted into a frame or a casing of the mobile phone antenna which is to be printed; and (4) the frame or the casing is printed with the mobile phone antenna using a conductive printing ink; and (5) the mobile phone antenna is dried at a temperature of 60 to 200 DEG C so as to obtain the mobile phone antenna. Compared with existing technology, printing times of the technological method are reduced, production yield is increased, and production cost is reduced.

Description

technical field [0001] The invention relates to an ink for a mobile phone antenna, in particular to a process for printing a mobile phone antenna. Background technique [0002] Nowadays, the development of electronic products is changing with each passing day, and the functions are becoming more and more powerful, while the products are getting smaller and thinner. As one of the important components of electronic products, the performance and size of antennas are directly related to the quality of electronic products. With the miniaturization of wireless communication products, built-in antennas gradually replace external antennas and become the mainstream of antenna design. [0003] For example, the existing mobile phone antennas are usually prepared by the following methods: First, using a flexible printed circuit board (Flexible Printed Circuit Board) process, referred to as FPCB or FPC, is a printed circuit with a pattern made of a flexible substrate. The board is compo...
