According to the upstream and downstream of the industrial chain, it can be divided into raw materials, copper clad plates, printed circuit boards, electronic product applications, etc., and the relationship is simple as follows:
Glass fiber cloth: Glass fiber cloth is one of the raw materials of copper clad plate, made of glass fiber yarn textile, accounting for about 40% of the cost of copper clad plate (thick plate) or 25% (sheet). Glass fiber yarn is calcined into liquid by silica sand and other raw materials in the kiln. It is drawn into very fine glass fiber through a very fine alloy nozzle. Then hundreds of glass fiber are twisted into glass fiber yarn. Kiln construction investment is huge, generally need hundreds of millions of funds, and once the ignition must be 24 hours uninterrupted production, the cost of entry and exit is huge.
Copper foil: Copper foil is the raw material accounting for the largest proportion of the cost of copper clad plate, accounting for about 30% (thick plate) or 50% (sheet) of the cost of copper clad plate, so the price rise of copper is the main driving force of the price rise of copper clad plate.
