The working principle of the circuit board is to use the board-based insulating material to isolate the surface copper foil conductive layer
The working principle of the circuit board is to use the board-based insulating material to isolate the surface copper foil conductive layer, so that the current flows along the pre-designed route in various components to complete functions such as work, amplification, attenuation, modulation, demodulation, coding, etc.
The traditional circuit board, using the method of printing etching resist, to make the circuit line and drawing, so it is called printed circuit board or printed circuit board. Due to the continuous miniaturization and refinement of electronic products, most circuit boards are currently attached with etching inhibitors (film pressing or coating), and then etched to make circuit boards after exposure and development.
With the expansion and development of electronic products in various industries, PCB applications are also evolving. Nowadays, PCBs are widely used in electronic products, and the types of PCBs are also diverse. They can be single-sided, double-sided or multi-layered. They may be rigid, flexible, and may contain both rigid and flexible components.
