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.

 

PCB laser marking machine

 

As people's emphasis on environmental protection, the advantages of laser marking compared with traditional ink jet is more and more prominent, the laser marker can processing serial number and the qr code, etc., to record relevant production information, ease of traceability and quality control in the whole process of the electronic products. In the PCB manufacturing industry, laser tag application is presents the fast growth the tendency.

 

PCB fu yards of traditional way is to stick a Label tag or inkjet tags, these methods have some disadvantages in the process of machining.

 

The following for PCB laser marking and comparison of the advantages and disadvantages of traditional fu code

 

PCB industry: laser marking compared with the advantages and disadvantages of traditional processing

 

PCB brush machine is devised laser research and development of a new circuit board cleaning equipment, instead of traditional fiber brush machine machine and eraser. Laser output laser machine, then through high-speed scanning galvanometer circuit board cleaning function of system implementation, and is mainly used in the camera usb drive circuit board, circuit boards, such as card reader circuit board surface cleaning, make the circuit board conductive performance is stronger, sexual contact, better effect is better, and to wipe brush is the traditional artificial plate plate speed 10 times.

 

The disadvantage of traditional processing methods:

 

1, through chemical reagents to clean;

 

Use chemicals to clean. This method has certain pollution to the environment, more have after cleaning can not completely remove the moisture inside the PCB substrate and lead to hidden in the product after dependend short-circuit or leakage hidden trouble. Has very little dependend factory using this method.

 

2, by artificial manual erase;

 

Human use rubber block or fiber rod clean division. This disadvantage is that the workers operating strength, enthusiasm is not high, the production efficiency, especially the PCB after SMT cleaning, clean the quality is unstable, and requires a lot of manpower.

 

3, through the brush machine this automation equipment to erase;

 

Brush machine with circular article rubber or fiber brush divide. This method is the use of human power is replaced by clean plate, the maximum limit reduce the work intensity of the workers; High production efficiency, and workers use energy in comparison with the practices of bank, up by more than three times the production efficiency; According to different degree of oxide layer PCB proofing and dirt to select different clean technology parameters; Article with circular rubber or fiber, electric brush vertical high-speed rotating machine remove practices, from near the bond fixed position of SMT components, ensuring the quality of clean

 

The advantages of laser processing

 

1, Windows Chinese interface, easy to understand;

 

2, precision of CCD image visual teaching achieve rapid programming;

 

3, arbitrary point, 3 d irregular line such as line, arc or face continuous rubbing plate;

 

4, high speed, low noise brushless dc motor speed regulation make bank effect is better;

 

5, strong fixation of dust system;

 

6, static eliminator can put the static elimination within + / - 100 v;

 

7, the level of bank automatic compensation function, make the operation more convenient;

 

8, domestic feeder plate, suitable for different artifacts
