In this process, all surface areas and boreholes are plated with copper, some resistance is poured on the surface of the unwanted copper, and then etching resistance metal is plated.
Soft and hard combination board is considered appropriate and the use of rigid (FR4) materials and flexible (PI or PET) materials combination, is a kind of both rigid PCB durability and flexible PCB suitable force of the new printed circuit board.
If the contact or line on the PCB circuit board needs to contact with the parts over and over again, with the passage of the product office hours, the appearance of the metal will reveal a certain wear, so the contact is not good.
Flexible circuit board has the characteristics of short, small, light and thin; It has the characteristics of high assembly density and small volume. There are high cost, long cycle, complex inspection methods, etc., which is a process that all FPC circui
