What affect the cost of FR4 material?

Epoxy glass cloth laminate is made of electrical alkali-free fiberglass cloth impregnated with epoxy resin and suitable organic fillers, by processing under pressure and heat it will form rigid insulating materials. Including the G-10, FR-4, FR-5 and several species, FR-4 is the greatest demand for the production of CCL industry, FR-4 substrate widely used in computer components and peripheral equipment, such as motherboards, hard drives and other products, printed circuit boards are made from FR-4 substrate and cu sheet.

For example, normal TG, 4mil CCL sheet. Raw materials accounting for 80 percent, utilities and other, labor, depreciation accounting for 8%, 8%, 4%. As in raw materials detail, copper accounts for 63% of the cost, glass cloth accounted for 10% of costs, resin accounted for 7 % costs. Obviously raw material prices especially copper prices make impact greatly on the CCL.

From the beginning of 2012, copper prices of raw materials continuously goes up, which has seriously affected the profitability of the copper foil and the CCL industry, in further which affect the entire PCB industry chain, resulting in business investment enthusiasm waned in pcb raw material supplier. Companies began to consider the professional development of supplying chain, reducing the risk of rising raw material costs and shipping.
