Description

Composite offline tooling module structure

The invention relates to a tooling structure applied to a circuit substrate processing, in particular to a composite off-line tooling module structure.

Nowadays, the electronics industry is booming, and electronic devices have become an indispensable part of human life.

In the electronic device, the circuit substrate occupies a very important position, and most of the surface needs to be combined with the processed piece. When the processed piece is an insulating material or a shielded conductive material, in order to be fixedly bonded to the circuit substrate, the technical means are mostly the following three ways. The first type is a technical means such as soldering iron heating, second iron heating, and third fixed pressing machine heating.

In the first embodiment, the soldering iron is heated to 200 ° C for about 2 seconds. In the third application mode, the iron is heated to 180 ° C for about 3 seconds, and the third application mode is fixed pressure.

In the third mode of operation, it is not easy to change the mold. In the application process, accidents in which the worker is burnt often occur.
