PCB manufacturers show you the evolution of PCB production process. In the 1950s and early 1960s, laminates mixed with different types of resins and various materials were introduced, but PCB is still single-sided. The circuit is on one side of the circuit board and the component is on the other side. Compared with the huge wiring and cable,
Printed circuit board (PCB) is a board made of insulating and heat-insulating materials with a certain strength, which is fixed in the circuit and provides the connecting circuit between various components.
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.
