Market prospect analysis of copper clad laminate - understand the development and trend of copper clad laminate

Copper Clad Laminate (CCL for short) is a kind of plate-like material made of petroleum wood pulp paper or glass fiber cloth as reinforcement, dipped in resin, coated with copper foil on one or both sides, and hot pressed.

classification

According to the structure and structure classification, copper clad laminate can be divided into three categories: rigid copper clad laminate, flexible copper clad laminate and special material based copper clad laminate. Rigid copper clad laminate is a kind of copper clad laminate which is not easy to bend and has a certain hardness and toughness. Composite base copper clad laminate generally refers to a rigid copper clad laminate made of two or more reinforcement materials (paper, glass fiber cloth, glass felt, etc.) and resin by pressing. Flexible (flexible) copper clad plate is made of flexible reinforcing material (film) covered with electrolytic copper foil or calendered copper foil. Its advantage is that it can be bent to facilitate the assembly of electrical components.

Industrial chain

Copper clad laminate (CCL) is the upstream core material of printed circuit board (PCB), accounting for about 35% of the cost of PCB, and it is in the middle of the entire PCB industry chain. The upstream of the CCL is mainly made of glass fiber cloth, copper foil, epoxy resin and other raw materials. Among ordinary CCL, copper foil, glass fiber cloth and resin account for more than 90%. The downstream industry is printed circuit board, and the terminal industry is downstream complete equipment such as communication, computer, household appliances, automobile, aerospace, etc.
