How much do you know about copper clad laminate (CCL)? Let me explain.

Copper clad laminate (CCL) is the core substrate for PCBs, with downstream applications in communications, computers, automotive, industrial, and medical fields. Its upstream suppliers include raw materials such as copper foil, resin, and glass fiber, while its downstream suppliers include PCB manufacturers and end-use electronic product manufacturers. This industry is highly cyclical and is entering a new growth cycle, driven by emerging demands such as 5G, AI servers, and automotive electronics.

CCL is a sheet material made by hot-pressing a reinforcing material impregnated with resin, coated on one or both sides with copper foil, and then hot-pressed. It fulfills the three main functions of conducting electricity, insulating, and supporting printed circuit boards, making it a core material for PCB manufacturing.

The CCL industry chain has a clear three-tier structure: upstream raw material supply (copper foil, glass fiber cloth, resin, filler, etc.), midstream CCL manufacturing, and downstream PCB applications.

The three core raw materials for CCL are copper foil, resin, and glass fiber cloth, accounting for 42%, 26%, and 19% of the cost, respectively, for a total of 87%.
