PCB (printed circuit board) assembly industry chain analysis
Fiberglass cloth: fiberglass cloth are CCL raw materials, textile made from glass fiber, about 40% of the CCL costs (slab) and 25% (sheet). Manufacture of fiberglass cloth and weaving enterprises similar to control the capacity and quality by controlling the speed and specifications are relatively simple and stable, since World War II, almost no change much on the specifications. And CCL, the price of fiberglass cloth by the relationship between supply and demand the greatest impact in recent years, the price fluctuated between 0.50 ~ $ 1.00 / m. Production capacity in Taiwan and Mainland China accounted for about 70% of the world. Critical of the relationship between upstream and downstream of trading, the price of a loom for 10 to 15 million, is generally more than 100 sets of normal production, but higher funding requirements of the subsequent heat treatment and chemical processing equipment, up to ten million, weaving capacity expansion easier, more flexible.
Copper: copper accounted for the largest share of CCL cost of raw materials, accounting for more than 30% (thick plate) and 50% (sheet) of the CCL costs, copper foil prices is the main driving force of CCL prices . Wider application of copper foil, not only applied to the laminate industry, when the CCL industry downturn, the copper foil manufacturers are converting to other uses copper foil. Copper prices closely reflect the change in the price of copper, with the steadily rising price of copper, the copper foil manufacturers cost pressures to the downstream transfer. Copper foil industry's high-tech barriers lead to insufficient domestic supply of high-grade copper foil is still a large number of imports, the cost of investment in enterprises.
Copper clad laminate (CCL): based on electronic-grade glass fabric substrate impregnated with epoxy resin after drying, made of semi-cured state bonded piece, and then in the single-sided, double-sided or multilayer board before putting a thin plate of copper foil made by hot-pressing process conditions, the direct raw material of the PCB. CCL industry the demand for funds, small-scale plant is about 50 million yuan, the higher concentration, there are about 100. CCL industry is a cyclical industry of the cost drivers, in the upstream and downstream industry chain structure CCL strong bargaining power of the PCB, as long as the downstream demand is acceptable, the pressure of rising costs can be passed on to downstream PCB assembly manufacturers, but the only large scale The CCL has a strong voice in the glass fiber cloth, copper and other raw materials procurement. CCL's products use a single, can only be sold to printed circuit board factory, when PCB downturn, only lower prices in order to ensure capacity utilization.
PCB: relative to the upstream and downstream industries, the printed circuit board industry characteristics to determine their industry concentration is not high; in the fierce market competition environment, only those market positioning and operational efficiency of enterprises with long-term competitiveness, an ordinary PCB The production line requires more than ten million yuan, the Multilayer required to put 50 million, the HDI need to put more than 200 million yuan. Huge industry, the division of labor is very fine, single-station process outsourcing, specializing in drilling, such as an oversupply of low-end products. HDI and other high-end printed circuit board industry is capital, labor-intensive industry, management and technical requirements is relatively high, often become the bottleneck capacity expansion.
