Printed circuit PCB is a key piece of electronic products , known as " the mother of electronic sub- system products , " reputation .
Manufacture of printed circuit board products, processing technology because of various different types of products , generally can be divided into six stages: system board , assembly , drilling , cutting , printing and testing . The import of foreign suppliers to provide manufacturing equipment market accounted for most of the market , its price is often 2-5 times that of domestic equipment , and some even up to 10 times. A higher degree of equipment made mainly part of the etching plate machine , lamination machine and exposure machine , network printer printing sectors , the electrical test test test link machine .
In 2008, factories in mainland China to provide the printed circuit board manufacturing equipment to achieve total sales of 8 billion yuan , of which 92.5% of sales by local vendors . Printed circuit board production equipment involved in a number of markets are more dispersed, Han's Laser , kodje , and the Chi Sheng Bo can only hold four Chinese PCB manufacturers of printed circuit board manufacturing equipment supply market, the market share of 8.5% .
IPC ( Association of American printed circuit board ) on May 27 announced in April 2010 the whole North American printed circuit board (PCB) manufacturer -to-bill ratio (book-to-billratio) increased to 1.10 , for the 12th consecutive month Greater than 1 . 1.10 shipping 100 U.S. dollars per month means that the product would have received new orders worth 110 dollars .
Combination of all domestic and international factors , I believe that the financial crisis of the printed circuit board market in the development of the next three years will show an increasing trend , the market demand will gradually increase .
But the printed circuit industry problems can not be overlooked : First, the weak autonomy . Basically in foreign-invested enterprises "unified "situation , the export value of foreign-invested enterprises accounted for over 8 percent of gross exports to total exports of processing trade export value of over 9 percent , exports of Guangdong printed circuit capacity remains weak autonomy . Second, the industry is heavily polluting the environment industry . Printed circuit board production process must spend a lot of water , and because the printing , etching and other processes use a variety of chemicals and special materials , their production of wastewater, waste and waste treatment will be if no strict environmental Causing serious pollution .
In accordance with the "electronic information industry restructuring and rejuvenation plan " requirements , enterprises should increase the printing circuit core technology investment , promote domestic printed circuit industry upgrading , Jiakuaipeiyu have Zizhu Zhishichanquan of Da clusters , and enhance its core competitiveness. At the same time , vigorously develop the "recycling economy" , path of sustainable development , good regional industrial undertaking and transfer . In attracting foreign investment or to undertake the transfer of printed circuit industry , should focus on overall planning , not only to consider economic efficiency, should also consider environmental sustainability in the region to avoid attract an industry to undermine a serious environmental consequences .
