The following is the PCB circuit board laser marking machine solution

PCB is one of the important components of the electronics industry. The output value of the industry accounts for about a quarter of the total output value of electronic components. It accounts for the largest proportion in the various electronic component sub-industries, and the flexible PCB board (ie FPC) is the growth in the PCB industry. One of the fastest sub-industries. From the perspective of development trends in various regions of the world, after large-scale reorganization, migration and technology replacement, domestic PCB and FPC production and processing companies have seized the opportunity to transfer electronic products to the country, which has further increased the proportion of domestic circuit board output in the international market.

At the same time, with the development of the circuit board industry, inkjet printers play a pivotal role in the production line. In order to prevent counterfeiting in the same industry and effectively manage regional sales, manufacturers will use high-tech anti-counterfeiting methods to identify their products. At this stage, companies in the industry generally use inkjet printers, and some problems continue to emerge: such as large consumption of consumables, high costs, the need for professional maintenance personnel, easy erasure and change of marking effects, and high pollution.

As people pay more attention to environmental protection, the advantages of laser marking over traditional inkjet marking have become more and more prominent. Laser marking can process serial numbers and QR codes to record relevant production information and facilitate the full traceability and traceability of electronic products. Quality control. In the PCB industry, laser marking applications are showing a trend of rapid growth.

The traditional coding method for PCB circuit boards is labeling or inkjet marking. These methods have many drawbacks in the processing process.

Circuit board laser cleaning machine

Circuit board laser board cleaning machine is a new type of circuit board cleaning equipment developed by Chuangxiang Laser, which replaces traditional fiber rod board cleaning machine and eraser board machine. The laser board cleaning machine outputs the laser, and then realizes the circuit board cleaning function through the ultra-high-speed scanning galvanometer system. It is mainly used to clean the surface of the U disk circuit board, camera circuit board, card reader circuit board, etc., to make the circuit board more conductive. , The contact is better, the bonding effect is better, and the speed of wiping the board is 10 times of the traditional manual wiping speed.

Disadvantages of traditional processing methods:

1. Clean with chemical reagents;

Use chemical reagents to clean. This method has a certain pollution to the environment, and there is a hidden danger of short circuit or leakage in the bonded product because it cannot completely remove the moisture in the PCB matrix after cleaning.

2. Manually erase by hand;

Manpower uses rubber blocks or fiber rods to erase. The disadvantages of this method are that the workers have high work intensity, low enthusiasm, and low production efficiency, especially after cleaning the PCB after SMT. The cleaning quality is very unstable and requires a lot of manpower.

3. Erase by automatic equipment such as a wiper;

The wiping machine is equipped with a round rubber strip or fiber strip erasing method. This method uses electricity instead of manpower to wipe the board, which greatly reduces the work intensity of the workers; the production efficiency is high, and the work of the workers using force to wipe the board Compared with the method, the production efficiency is increased by more than 3 times; different cleaning technical parameters can be selected according to the different degrees of oxidation layer and dirt of the PCB; equipped with round rubber strips or fiber strips, the electric wiper is vertical and high-speed rotation cleaning operation method , To ensure the cleaning quality.

Advantages of laser processing

1. WINDOWS2000 Chinese operation interface, easy to learn and understand;

2. Accurate CCD image visual teaching realizes fast programming;

3. Irregular lines or surfaces such as arbitrary points, three-dimensional straight lines, arcs, etc., are continuously wiped;

4. High-speed, low-noise speed-regulated DC brushless motor makes the cleaning effect better;

5. Powerful dust collection device;

6. The static eliminator can eliminate static electricity within ±100V;

7. Combined with the above PCB circuit boards, the function of automatic compensation for the rubbing force makes the operation more convenient;
