Improve the overall competitiveness of the industry chain of printed circuit boa
Printed circuit board (Print edcircuit board, referred to as PCB) are assembled Electronic Substrate used parts are scheduled in the common substrate between the connection point of the design and printing of the formation of PCB components. The main features of the product is scheduled to make a variety of electronic components forming the circuit connection, the role of transmission from the relay, is the key to electronic interconnect electronics parts. Print Circuit board manufacturing quality not only directly affect the reliability of electronic products, and products affecting the overall competitiveness of the system, so Printed circuit board Known as "the mother of electronic system products." Printed circuit board industry, the development can to some extent reflect a country or region of the electronics industry speed the development of technical standards.
Glass fiber: glass fiber yarn by the silica sand and other raw materials into a liquid in the furnace burning through very small nozzle pull into a fine glass fiber alloy, then hundreds of root bound Jiaocheng glass fiber glass. Kiln building huge investment for capital-intensive industries, 30,000 tons of furnace required 400 million yuan, the new furnace needs 18 months, business cycle is difficult to grasp, and once the ignition must be 24-hour production, and over five years about half a year must be discontinued maintenance, entry and exit costs enormous.
Fiberglass cloth: glass fiber cloth is one of CCL's raw materials, from glass fiber yarn Textile Formed about 40% of the cost of CCL (thick) and 25% (thin). Manufacture of glass fiber cloth and weaving companies are similar, you can control the speed to control the production and quality, and standard single and relatively stable since World War II almost did not change much on the specifications. And the CCL is different from the price of fiberglass cloth most affected by supply and demand in recent years the price of 0.50 to 1.00 USD / m fluctuates between. Taiwan and Mainland China's production accounted for 70% of the world. The relationship between upstream and downstream key for the operation, a loom price for 10 to 15 million, generally more than 100 production may be normal, but the subsequent heat treatment and chemical processing equipment require a higher capital reached 10 million, weaving The capacity expansion easier and more flexible.
Copper: Copper is the largest share of total raw materials cost CCL, CCL costs account for about 30% (thick) and 50% (thin) or more, so the prices of copper foil is the CCL price rise the main driving force. Wider application of copper, not applied to copper clad laminate industry, industry downturn, when the laminate, copper foil manufacturers can produce other uses of copper. Closely reflect the price of copper in the copper price changes, rising steadily as copper, copper foil cost pressure on manufacturers to shift to the lower reaches. Copper industry, the domestic high-tech barriers lead to inadequate supply of high-grade copper foil still a lot of imports, investment in enterprises in the cost are also high.
Copper clad laminate (the CCL): is electronic-grade glass fiber cloth as the substrate, impregnated with epoxy resin, after drying, the state made of semi-curing adhesive film, and then in the single-sided, double-sided Rubbing plate or multilayer thin copper foil surface, a special made hot pressing process conditions, is the direct PCB materials. CCL industry demand for more funds, small-scale plant is about 50 million yuan or so, the higher concentration, there are 100 or so. CCL is a cost-driven industry, cyclical industries, the upstream and downstream industry chain structure, CCL strong bargaining power on the PCB, as long as the downstream demand is acceptable pressure of rising costs can be passed on downstream PCB manufacturers, but only large-scale The CCL can be glass fiber cloth, copper and other raw material procurement has a strong voice. Because the product uses a single laminate, printed circuit boards can only sell plants, when the PCB downturn can only keep the prices down 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 with good market position and operational efficiency of enterprises that have the long-term competitiveness, a common PCB production line needs 2 more than 10 million yuan, need to put 5 million multilayer, HDI be invested 200 million yuan or more. As a huge industry, division of labor is very small, there is specialized in drilling and other single-station process outsourcing, low-end surplus. HDI and other high-end printed circuit board industry is capital, labor-intensive industries, the management and technical requirements are relatively high, often become the bottleneck capacity expansion.
