The manufacturing process of copper clad laminate (CCL) is to impregnate the reinforcing material with organic resin and dry it to form a prepreg. A blank made of several prepregs laminated together, one or both sides covered with copper foil, and a plate-shaped material formed by hot pressing.

From the cost point of view, copper clad laminates account for about 30% of the entire PCB manufacturing. The main raw materials of copper clad laminates are glass fiber cloth, wood pulp paper, copper foil, epoxy resin and other materials. Among them, copper foil is the main raw material for manufacturing copper clad laminates. , 80% of the material proportion includes 30% (thin plate) and 50% (thick plate).

The difference in performance of various types of copper clad laminates is mainly manifested in the differences in the fiber reinforced materials and resins they use. The main raw materials required to produce PCB include copper clad laminate, prepreg, copper foil, gold potassium cyanide, copper balls and ink, etc. Copper clad laminate is the most important raw material.

The PCB industry is growing steadily

The widespread use of PCBs will strongly support the future demand for electronic yarns. The global PCB output value in 2019 is about 65 billion U.S. dollars, and the Chinese PCB market is relatively stable. In 2019, the Chinese PCB market output value is nearly 35 billion U.S. dollars. China is the fastest growing region in the world, accounting for more than half of the global output value, and will continue to grow in the future .

Regional distribution of global PCB output value. The proportion of PCB output value in the Americas, Europe, and Japan in the world has been declining, while the output value of PCB industry in other parts of Asia (except Japan) has rapidly increased. Among them, the proportion of mainland China has increased rapidly. It is the global PCB industry. The center of the transfer.
