From the current regional location of the company, we think that the company has relative location advantages. From the distribution of PCB industry in China, PCB is mainly concentrated in the Pearl River Delta and the Yangtze River Delta, which accounts for almost 80% of the country. The north of the Yangtze River PCB manufacturers are relatively less, and around the Bohai Sea and nearby Qingdao due to the concentration of Samsung, Motorola, Sony Group Corp Ericsson and other home appliance manufacturers, such as Hisense, Haier and other home appliance manufacturers, the demand for PCB is also quite strong, the company faces relatively few competitors in this region, and has formed a certain popularity in the industry, which lays a good foundation for the company's future development. In addition, the company has provided batteries and LCD boards for Motorola, Hisense and other mobile phone manufacturers, and has established a good cooperative relationship. Once the company has mass production of HDI boards, the company has strived for the convenience of these manufacturers to become HDI board users. Our profit forecasts for 2007-09 are 0.32 yuan, 0.375 yuan and 0.534 yuan. Calculated with 0.375 yuan in 2008, the current stock price implies a dynamic price-to-earnings ratio of 37.9 times. We think the stock price is basically reasonable and give it a "wait-and-see" investment rating. At the same time, it is suggested that we should actively pay attention to the progress of the company's HDI project and adjust the profit forecast for 2009 accordingly.
