PCB accounts for about 25% of the market share in the entire electronic components industry chain. The upstream is the electronic basic material, and the downstream is the electronic equipment terminal industry. The demand for communication equipment, consumer electronics products, computers and related equipment accounts for about 80%. In the first half of the month, PC shipments worldwide maintained a year-on-year growth rate of approximately 20% year-on-year, and the sequential growth rate decreased after entering May. The demand for smart phone market makes the flexible board and HDI demand a lot. The export of electronic information products in China has witnessed a year-on-year growth in the first half of this year. In May, it was 50% higher than the same period of last year. Exports have boosted PCB demand. Price changes are the main lines of research in the first half of the year. The price of PCBs has increased by about 10-15% between February and February this year, and PCB manufacturers have recently raised the price of components by 20% again. The price of copper-clad laminates will begin to drop by about 3%-5% in July. Although the expected price cuts are uncertain, at least there will be no 20% increase in prices in the first half of the year. Copper prices, which account for about 60% of PCB costs, will fluctuate little this year, so you can It is estimated that the gross margin of PCB will increase in the second half of the year and increase by approximately one percentage point to 10%. PCB industry Q3 is still booming. Due to the recovery of the component industry in the second half of 2009, the base number is large, so the growth of PCB sales in the second half of this year will fall back, but the industry boom continues to Q3 is not a problem. The increase in demand for flexible PCBs will also be stable. Domestic PCB companies have begun to take advantage of their economies of scale. The sales revenue of PCB enterprises above designated size in our country increased by 29.35% compared to the same period of last year, and the sales volume of Wuxi Jianding reached 5 billion yuan. The PCB industry appears to have high concentration of SMEs withdrawn, which will help large PCB companies, especially listed companies, to seize market share and exert scale advantages. The scale advantage is an important way for PCB companies to improve profitability.
