With the continuous development of society and the continuous progress of various industries, industrial production equipment is constantly being innovated on the original basis. Taking circuit board processing equipment as an example, traditional circuit board processing not only requires a lot of manual labor, but also often produces a large amount of sewage and exhaust gas containing metal ions, which causes considerable harm to the environment and water resources, and also harms the health of the staff. Health will also have an impact, so no matter from which aspects, we urgently need a horizontal sinking copper wire process to meet people’s needs.

The black shadow process is suitable for high-end FPC, 5G products, the mainstream process of high-end PFC, and is increasingly adopted by high-end FPC manufacturers. At present, the main representatives of the market are medicine dealers: Mai Demei, Le Si. Shenzhen Feishida Machinery Equipment Co., Ltd. and Mai Demei have successfully cooperated with many equipments, and many companies are in mass production.

Qualified raw materials are very important for electronics manufacturers, so the inspection of copper foil, which is one of the main substrates of FPC black hole line manufacturers, is even more important. The quality test and acceptance methods are as follows, which are worthy of your collection and reference. 　　 Take the sample material 250mm wide and cut it into 250mm×480mm. The cut material is subjected to SPS→lamination→exposure→etching-DES to form the circuit required for the test (double-sided etching is single-sided).

The FPC in the FPC black hole line is the abbreviation of Flexible Printed Circuit, also known as flexible circuit board, flexible printed circuit board, flexible circuit board, or FPC for short. It has the characteristics of high wiring density, light weight, and thin thickness. . FPC flexible printed circuit is a kind of highly reliable, excellent flexible printed circuit made of polyimide or polyester film as the base material. It has many advantages that rigid printed circuit boards do not have. It can Free bending, winding, and folding can be arranged according to the space layout requirements, and can be moved and stretched freely in three-dimensional space, so as to achieve the integration of component devices and wires. This kind of circuit can not only be bent at will, but also has light weight, small size and heat dissipation performance. Good, easy to install, breaking through the traditional concept of interconnection technology.
