Abstract

The invention relates to a technology for manufacturing a printed antenna through PIN feed points. The technology comprises the following steps that firstly, PIN needles are printed with printing ink with strong adhesive force; secondly, the printed PIN needles are dried at the temperature ranging from 60 DEG C to 200 DEG C; thirdly, the dried PIN needles (obtained in the second step) printed with the printing ink are inserted into a machine frame or a machine shell of an antenna to be printed; fourthly, conductivity printing ink is used for printing the antenna on the machine frame or the machine shell; fifthly, the printed antenna is obtained after the antenna printed with the conductivity printing ink is dried at the temperature ranging from 60 DEG C to 200 DEG C. Compared with the prior art, the technology has the advantages of being less in procedures, good in effect, low in cost and the like.

Description

technical field [0001] The invention relates to an antenna ink, in particular to a process for manufacturing a printed antenna by using a PIN feeding point. 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 boar...
