Printed circuit board according to the chain to the classification, can be divided into raw materials - CCL - printed circuit board - electronics applications, the relationship simply expressed as: fiberglass fabric: fiberglass cloth is one of CCL's raw materials, from glass textile yarn made of fiber, about 40% of the cost of CCL (thick) and 25% (thin). Silica sand and other raw materials, glass fiber yarn by the calcination in the kiln into a liquid alloy through a very small pull into a fine glass nozzle, and then wrapped around the mountain of hundreds of glass fiber yarn under glass. Huge investment in the construction of the kiln, it generally takes hundreds of millions of money, and once the ignition must be 24-hour production, entry and exit costly. Manufacture of glass fiber cloth and weaving companies are similar, can be controlled by controlling the speed of production and quality, and specifications relatively simple and stable, since World War II almost no 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 U.S. $ 0.50-1.00 / m fluctuated between. Taiwan and Mainland China's production capacity accounted for 70% of the world.
printed circuit board(pcb&pcba) copper: Copper is accounted for the largest proportion of the cost of raw materials CCL, CCL costs account for about 30% (thick) and 50% (thin), so the prices of copper prices is the main CCL driving force. Copper prices closely reflect changes in the price of copper, but the bargaining power is weak, with the recent rises in copper prices, copper companies struggling, many companies forced to close or merge, even if the copper laminate manufacturers to accept Manufacturers of copper foil prices are still in widespread losses. As the price gap appears, the first quarter of 2006, another wave is highly likely market price, which may lead CCL prices.
printed circuit board(FPC&PCB) CCL: CCL is based on epoxy resin as the fusion agent and the copper foil laminated glass cloth with the product of the PCB directly to raw materials, after etching, plating, multilayer lamination system after into printed circuit boards. CCL industry demand for capital is not high, about 3000-4000 million, and can be discontinued at any time or converting. Upstream and downstream industry chain structure, CCL's bargaining power the strongest, not only in the glass fiber cloth, copper and other raw materials procurement has a strong voice, and as long as the downstream demand still, you can pass on the pressure of rising costs downstream PCB manufacturers. The third quarter of this year, CCL began to raise prices, price increases in the range of 5-8%, the main driving force is reflected in copper prices and lower demand can absorb CCL manufacturers shifted upward pressure. World's second largest laminate manufacturer in South Asia on December 15 was also increased prices, showing that at least the first quarter of 2006, the form of a good PCB needs.
