PCB manufacturing can be more environmental protection and energy saving

PCB is electronic components industry development pillar

Printed circuit board development level in a certain extent, reflect a country or a region the development speed and technical level of the electronics industry.

Printed circuit board is closely related to electronic product development, is one of the important electronic components have the characteristics of multi-function, integration. It is assembled with the substrate components and the main function is to make all kinds of electronic components to form a predetermined circuit connection, ACTS as relay transmission, is the key to the electronics interconnection. The manufacture of printed circuit board quality not only directly affects the reliability of electronic products, and influence the overall competitiveness of the products. Printed circuit board, therefore, referred to as the "mother of the electronic system, its development level can to a certain extent, reflect a country or a region the development speed and technical level of the electronics industry.

At present, the global PCB industry output value of more than a quarter of the total output value of the electronics industry, is the largest proportion in the various electronic components industry segment industries, as well as the most active contemporary electronic components industry industry. Due to the improvement of accuracy and complexity, the proportion of the value in the machine costs increased, instead is the mainstay of the electronics industry.

Global PCB production value of about $2011 in 58.9 billion, up 4.7% from a year earlier, the output value of about $23.5 billion in China, about 40% of the world, an increase of about 6.7%. The printed circuit board industry in China to go through the process from scratch, although development speed quickly, but still about 90% more than for the small and medium-sized enterprise, the enterprise scale, technology and management level and global compared to large enterprises, there is still a large gap should speed up the development.

PCB industry does not belong to the electroplating industry

Dozens of working procedure of PCB manufacturing process, there is a plating process, cannot therefore consider the industry electroplating industry.

In order to speed up the development of our country's electronic information industry as the printed circuit board in China national brand companies striving hard, strive for in the industrial scale, technology and the world first-class enterprise is neck and neck, but encountered development predicament. Individual governments and Banks - not understanding some department of the industry, wrong to regard the industry as a heavy pollution especially heavy metal pollution industry and tries to kill, mainly manifested in two aspects: one is to keep the industry out of a certain region, the second is that the Banks think risk big and refused to lend.

By convention, the product of form a complete set of production chain best within 200 kilometers. For a region, if the local PCB industry move out, so will certainly move with electronic information products manufacturing, is bound to bring great influence to the local economic development. Printed circuit board industry is high investment, high return industry, a simple production line requires tens of millions of dollars of investment, and HDI production line need hundreds of millions of yuan. Without the support of banking, the domestic PCB industry will shrink, resulting in China's electronic information products used by the printed circuit board back to depend on the situation of foreign enterprises.

Of dozens of working procedure in the printed circuit board manufacturing, there is a line of electroplating process, but not so to the industry as a metal plating industry in manufacturing. Printed circuit board manufacturing of electroplating is a procedure in continuous production line, can't also did not bring out the part as a separate enterprise production. If on the production line for every parameter control and accurate, and can minimize the pollution. And compared with spare parts for the production characteristics of electroplating enterprise, printed circuit board manufacturing of plating is on the printed circuit pull local electroplating, plating is not only less species, and the water is a much smaller. In terms of heavy metal pollution, emissions of waste water in the printed circuit board manufacturing mainly in copper, still have a small amount of nickel, according to the management of the existing technology, can put the waste water of the two kinds of metal forming metal mud and eventually become a smelter of raw material, so the printed circuit board industry as there is no science in according to the pollution of heavy metals industry, lenovo is one-sided.

PCB production will more energy conservation and environmental protection

As the printed circuit board production development in the direction of high precision, high density, makes production of PCB, more environmental protection energy conservation and emissions reduction.

With light, thin, small electronic products gradually requirements, printed circuit board production development in the direction of high precision, high density, embedded discrete device technology, using the mathematics of ink-jet printing printing electronic technology, high heat metal base printed pull the development of technology, such as making PCB production more and more environmental protection energy conservation and emissions reduction.

Set by the environmental protection organization of HJ, 450-450 "clean production standard - printed circuit board manufacturing" published on November 21, 2008, in February 1, 2009 formally implemented. The standard explicitly pointed out that, since the date of implementation of this standard, the clean production standards - plating industry "(HJ - 2006-314) involved in the" printed circuit board type "data requirements will be replaced. At the same time, the national standard "electronic industrial pollutants emission standards - electronic components, printed circuit board is under approval.
