The upstream raw materials of PCB mainly include key components such as copper-clad laminate (CCL), copper foil, semi cured sheet, and ink, providing basic support for PCB manufacturing.

Copper clad laminate is the main source of PCB cost, and its quality directly affects the performance and cost of PCB.

Copper clad laminates play an important role in interconnection, conductivity, and support, mainly composed of key materials such as copper foil, fiberglass cloth, and epoxy resin. Based on the coating or impregnation of glass fiber cloth with polymer resin, and then hot pressed with copper foil, it has excellent conductivity and excellent insulation and support functions.

Fiberglass cloth is a reinforcing material that can effectively enhance the strength and insulation performance of circuit boards; Synthetic resin tightly adheres glass fiber cloth to ensure the stability and reliability of the circuit board.

From the supply side, the overall supply of upstream raw materials for PCBs in China is relatively abundant, which is sufficient to meet the basic development needs of the domestic PCB industry.

Downstream PCB products in the industrial chain are widely used in many fields such as communication, consumer electronics, and automotive electronics.
