According to the industry chain to the downstream, can be divided into raw materials, CCL, printed circuit boards, electronic products applications.

Fiberglass Cloth: Fiberglass is one of the raw materials of CCL and is made of fiberglass yarn, which accounts for 40% (plate) and 25% (sheet) of CCL cost. Fiberglass cloth manufacturing and weaving enterprises are similar, you can control the speed to control production capacity and quality, and specifications are relatively simple and stable. Unlike CCL, the price of fiberglass cloth is most affected by supply and demand, and the price in recent years fluctuates between $ 0.50 and $ 1.00. Taiwan and mainland China's production capacity accounted for about 70% of the world.

Copper foil: copper foil is the largest proportion of CCL cost of raw materials, about 30% of the cost of CCL (plate) and 50% (sheet), so the price of copper is the main driving force for CCL prices.

CCL: CCL is a product of laminating fiberglass and copper foil together with epoxy resin as a fusion material. It is a direct raw material of PCB. After etching, electroplating and laminating, the printed circuit board.
