Printed board blanking, hole and shape processing can be used die blanking method, for simple processing PCB or PCB requirements are not very high can be used blanking method. It is suitable for the production of low level and large volume PCB and PCB whose shape requirements are not very high, and its cost is low.

Punching:

The production batch is large, the type and number of holes are large, and the shape of the complex single-sided paper substrate and the epoxy glass cloth substrate with double-sided nonmetallic holes are usually punched by one or several molds.

Shape processing:

Printed boards are produced in large batches of single panel and double panel shapes, usually using die punch. According to the size of the printed board, it can be divided into upper blanking die and falling die.

Composite processing:

High precision is required between the hole and the hole, and between the hole and the shape of the printed board, and in order to shorten the manufacturing cycle and improve productivity, the composite die is used to process the hole and the shape of the single panel at the same time.

The key is the design and processing of the mold, which requires professional technical knowledge. In addition, the installation and debugging of the mold is also very important. At present, most of the molds of PCB manufacturers are processed by external factories.
