Problems solved by technology

[0003] The purpose of the present invention is to provide a flexible circuit board steel sheet reinforcement hot pressing manufacturing process with simple operation, wide applicability and high production efficiency, which can overcome the problem that the double-sided adhesive is easy to be heated in the conventional steel sheet reinforcement bonding process. Melting will cause the steel sheet to fall off or be misaligned; at the same time, it can solve the shortcomings of low work efficiency and low product compliance rate in the conventional steel sheet reinforcement bonding process

Abstract

The invention discloses a flexible printed circuit board steel disc reinforcing hot-pressing making process, including that pure glue is firstly adhered on the steel disc reinforcing position of the flexible printed circuit board and then steel disc is adhered, lamination curing is carried out to complete steel disc reinforcing, and the steel disc is fixed by steel disc adhesion jig. The invention adopts electric iron to preheat the steel disc firstly, so that certain stickiness is kept between the steel disc and the flexible printed circuit board and the steel disc can not drop in the process that the flexible printed circuit board is taken out and transferred; and the pure glue used for adhering the flexible printed circuit board and reinforcing the steel disc in steel disc hot-pressing process is thermosetting glue, namely glue system capable of being molten and cohered under heating condition and can be cured after curing at certain temperature for a while, so that the steel disc is firmly adhered on the flexible printed circuit board and can not drop in post making processes. The invention has simple making process and strong feasibility, can thoroughly avoid steel disc dropping and deviation problems and has wide applicability and higher production efficiency.

Description

technical field [0001] The invention relates to a circuit board processing technology, in particular to a flexible circuit board steel sheet reinforcing hot pressing manufacturing process. Background technique [0002] With the continuous innovation and development of high technology, the requirements for circuit boards are getting higher and higher, especially digital products pursue convenience and light weight. Flexible circuit boards with flexibility, ultra-thinness and light weight are used as high-tech products in The electronic field has been greatly developed and applied. At the same time, the requirements for its performance are gradually increasing. It cannot be ignored that compared with the traditional rigid circuit board, the rigidity and loadability of the flexible circuit board still have great deficiencies. , so it needs to be reinforced. Steel sheet is a kind of material for the reinforcement of flexible circuit boards. The conventional steel sheet producti...
