PCB (Printed Circuit Board) is the most common component in electronic devices, usually made by pressing multiple layers of conductive and insulating materials. It forms conductive patterns on insulating substrates through processes such as etching and electroplating, which are used to connect various electronic components and achieve electrical connections and mechanical support for circuits.

The main use of PCB:
Support and connection of electronic components: PCB provides reliable mechanical support for various electronic components, while achieving electrical connections between components through conductive graphics. This greatly simplifies the assembly process of electronic products and improves production efficiency.
Signal transmission: The conductive lines on the PCB can transmit various electrical signals, including digital signals, analog signals, etc. High quality PCB design can effectively reduce signal interference and improve the reliability of signal transmission.
Heat dissipation: Some PCB designs include heat dissipation functions, such as the copper foil heat dissipation layer commonly found in Jialichuang PCB multilayer, which can help dissipate heat and improve the stability and lifespan of electronic products.
Electromagnetic shielding: Some PCB designs can achieve electromagnetic shielding function through special layout and material selection, reduce electromagnetic interference, and improve the electromagnetic compatibility of products.
Miniaturization and Integration: The continuous advancement of PCB technology enables electronic products to be more compact and integrated.
