Overview of PCB Industry Structure
In the PCB industry, rigid PCBs account for approximately 70% of the market, making them the largest segment. The primary materials used in the manufacturing of rigid PCBs include:
1. Copper Clad Laminate (CCL);
2. Copper Foil;
3. Film;
4. Various Chemicals.
Key Material: Copper Clad Laminate (CCL)
Among these materials, Copper Clad Laminate (CCL) represents the highest proportion of raw material costs, typically ranging from 50% to 70% depending on the number of layers in the PCB. The core materials for CCL are fiberglass cloth and electrolytic copper.
