PCB industry chain analysis

PCB (Printed circuit board, referred to as PCB) is the substrate for electronic parts assembly, is the common substrate to form a predetermined point of the design and printing of the connection between the components of the PCB. The main function of the product is scheduled to make a variety of electronic components to form the circuit connection, from the role of relay transmission is the key to electronic product electronic interconnect components. Printed circuit board manufacturing quality, not only directly affect the reliability of electronic products, and the overall competitiveness of products of the system, so the printed circuit board is called "the mother of electronic system products." Printed circuit board industry level can be reflected to some extent a country or region of the electronics industry speed the development of technical standards.

Glass fiber: glass fiber yarn and other raw materials from the silica sand calcined in a kiln to a liquid, through very small nozzles pull into a very fine glass fiber alloy, and then wrapped around the mountain of hundreds of glass fiber yarn glass fiber roots. Kiln building huge investment for capital-intensive industries, 3 million tons of furnace needs 400 million yuan, the new furnace would take 18 months, business cycle is difficult to grasp, and once the ignition must be 24 hours a day production, but over five years about half a year must be discontinued maintenance, entry and exit cost is huge.

Fiberglass cloth: glass fiber cloth is one of CCL's raw materials, yarns made from glass, accounting for about 40% of the cost of laminate (plate) and 25% (thin). Manufacture of glass fiber cloth and weaving companies are similar and can be controlled by controlling the speed and quality of production, and the specification of relatively simple and stable, since World War II almost did not change much on the specifications. And CCL is different from the price of fiberglass cloth most affected by supply and demand in recent years the price of 0.50 ~ $ 1.00 / m fluctuates between. Taiwan and Mainland China's production capacity accounted for 70% of the world. The relationship between the upstream and downstream key for the operation, the price of a loom 10 to 15 million, more than 100 can be generally normal production, but the subsequent heat treatment and chemical processing equipment, high capital requirements, amounting to tens of millions, weaving The capacity expansion easier, more flexible.

Copper: Copper is the largest proportion of total cost of raw materials CCL, CCL costs account for about 30% (thick) and 50% (thin) or more, so the prices of copper prices is the main driving force of CCL . Wider application of copper foil, copper clad laminate is not applied to industry, industry downturn, when the copper clad laminate, copper foil manufacturers to conversions to other uses copper foil. Closely reflect the price of copper in the copper price changes, with the rises in copper, copper foil makers to shift to the downstream cost pressures. Copper industry, led to insufficient supply of high-tech barriers, still need to import large quantities of high-grade copper foil, the cost is also a great investment in enterprises.

CCL (referred to as CCL): is electronic-grade glass fiber cloth as the substrate, impregnated with epoxy resin, the drying treatment, made of half-cured state of the bond films, again in single, double or multi- board thin copper foil before putting the board through a special pressing process conditions is made, is the direct PCB raw materials. CCL industry demand for larger funds, small-scale plant is about 5,000 million, a higher concentration, there are 100 or so. CCL cost-driven industry is a cyclical industry, in the structure of downstream industry chain, CCL strong bargaining power on the PCB, as long as the downstream Xuqiu can still, you can pass the downstream pressure of rising costs PCB manufacturers, but only large-scale The CCL can be glass fiber cloth, copper and other raw materials procurement has a strong voice. CCL's products as single-use, printed circuit board plant can only be sold when the PCB downturn, lower prices only to ensure that capacity utilization.

PCB: relative to the upstream and downstream industries, and printed circuit board industry characteristics determine the degree of industrial concentration is not high; in the fierce market competition, only those good market position and operational efficiency of the enterprise to have a long-term competitiveness, a common PCB Production line 2 more than ten million yuan, MLB required to put 5 million, HDI need to invest 200 million yuan or more. As a huge industry, the division of labor is very small, have specialized in drilling and other single-station process outsourcing, low-end product supply. HDI and other high-end printed circuit board industry is capital, labor-intensive industry, the management and technical requirements are relatively high, often become the bottleneck capacity expansion.
