Circuit board (PCB) industry in line with the global economy has large cycle. In the past two years industry affected by the global economic downturn and computer sales, the boom of circuit board industry has been in a low state. Since the first half of 2014, the global economy to return to the boom up track, was also on the upside, circuit board industry. As the ministry‘s announcement, the approval of China telecom, China unicom FDD, TDD hybrid networking experiment, 4 g base stations of mass in the large-scale development of the construction and the intelligent terminal and will become pull the circuit board industry rapid development of the catalyst.

       PCB is one of the important components of the electronic industry, industrial output value of about a quarter of the total output value of electronic components, in various electronic components industry in the largest proportion, segment and flexible PCB board (FPC) is one of the fastest growing sector in the PCB industry. From various parts of the world development trend to see, after a major restructuring, migration and technology upgrading, domestic PCB, FPC production and processing enterprises seized the moment to electronic products to the domestic transfer, makes the domestic circuit board further increase the proportion of output value in the international market.

     At the same time, the development of PCB industry, spurt the code machine plays an important role on the production line. In order to prevent effectively for the regional sales of counterfeit and industry management, the manufacturer will use technology content high anti-counterfeiting means to identify their own products. Spurt the code machine widely used in the enterprises of the inline ink and some problems continuously emerging, such as material consumption, high cost, need professional maintenance personnel, marked effect is easy to erase changes, high polluting problems. Our company through in-depth investigation, found above problem due to the widespread use of ink printing machine has couldn‘t keep up with the pace of the development of the industry, and laser marking machine identification with its unique not daub of rubber seals has been widely used in industry.
