What is the PCB industry chain like?

The PCB industry plays a key role in the entire electronics industry chain.

The main raw materials required for the production of PCB include copper clad laminate, prepreg, copper foil, potassium gold cyanide, copper balls and ink.

Among them, copper clad laminate is the most important raw material. Copper clad laminate accounts for about 30%-40% of the entire PCB manufacturing cost. Copper foil is the main raw material for manufacturing copper clad laminate. The cost accounts for 30% (thin plate) and 50% (thick plate) of copper clad laminate.

The manufacturing process of copper-clad laminates is to impregnate reinforcing materials with organic resin and dry them to form a prepreg. A plate-like material made by laminating several prepregs together, covered with copper foil on one or both sides, and hot-pressed. The reason why various types of copper-clad laminates differ in performance is mainly due to the differences in fiber reinforcement materials and resins used.

According to Prismark data, in the global copper-clad laminate market share in 2023, Kingboard accounts for 14.6%, Shengyi Technology accounts for 14%, Taiwan Optoelectronics accounts for 10.3%, Nanya Plastics accounts for 9.1%, Panasonic accounts for 6.7%, and Lianmao Electronics Accounting for 6.3%, Taiyao Technology accounts for 4%, South Korea's Doosan accounts for 3.6%, Jinan Guoji accounts for 3.3%, and Nanya New Materials accounts for 3.2%.

Major copper foil manufacturers include Kingboard, Nanya Copper Foil, Copper Crown Copper Foil, Jiayuan Technology, Nord Co., Ltd., Longdianhuaxin, Changchun Chemical, Chaohua Technology, Jiangxi Copper Foil, etc.

Among downstream applications, the four major fields of communications, automotive electronics, consumer electronics, and servers account for a high proportion.
