1. What is PCB?
PCB stands for Printed Circuit Board, also known as a printed wiring board. It serves as the “connection hub + support frame” for electronic products—its core function is to connect various electronic components through circuits, allowing for smooth transmission of current and signals, acting as a critical “connecting bridge.”
The quality of PCBs directly affects the stability and longevity of electronic products; it can be understood as the skeleton of electronic products, which is why it is often referred to as the “mother of electronic products.”

3. Additional Notes
In the cost breakdown of PCBs, copper clad laminate accounts for approximately 27.3% of the highest cost, serving as the core material for PCB production, similar to the load-bearing walls of a house. Copper foil, resin, and glass fiber cloth are key materials. Electronic resin affects the performance of copper clad laminate, and with the increasing application of AI servers, the demand for silicon micropowder will continue to rise in the future!
