Printed circuit board (PCB), also known as printed circuit board. It is not only the carrier of electronic components in electronic products, but also the provider of circuit connection of electronic components. The traditional circuit board uses the method of printing etchant to make the circuit and drawing, so it is called printed circuit board or printed circuit board.
Flow chart of single-sided FPC circuit board: engineering documents - copper foil - Pretreatment - press dry film - exposure - Development - etching - film stripping - AOI - Pretreatment - coating film (or ink printing) - pretreatment before electroplating - electroplating - post electroplating - reinforcement - appearance punching - electrical measurement - appearance inspection - shipment;
As the name suggests, FPC flexible printed circuit board has the function of bending and using, and can be made into a three-dimensional space. Therefore, theoretically, only one FPC flexible circuit board / FPC flexible board can complete the overall wiring work in one machine.
Methods to judge the quality of FPC circuit board: 1： Distinguish the quality of the circuit board from the appearance Generally, the appearance of FPC circuit board can be analyzed and judged from three aspects
At present, there are two general FPC welding processes, one is tin press welding, and the other is manual drag welding.
