UV laser marking PCB QR code

Today's electronic products are obviously different from those of the past, and they are all developing towards intelligence and thinning. Consumers have higher and higher quality requirements for these products, and at the same time, they have also increased the demand for PCBs and processing technology. Manufacturers have to be more and more strict in the quality control of the PCB circuit boards of the components of electronic products in order to win the recognition of consumers and customers.

To achieve PCB quality control, it is necessary to use a product quality traceability system. Generally, through the marking technology of laser marking machine, one-dimensional code, two-dimensional code and other information are marked on the PCB board. Through the camera, the laser marking machine can be identified and uploaded to the database, and the unqualified products can be automatically eliminated to realize the whole internal The product quality traceability of the process, from the source supplier information to the product outbound data tracking, the whole process tracking, greatly improves the product quality, and realizes the control of product automatic production.

Earlier PCBs used inkjet to process information such as strings, images, contact information, and QR codes on the surface. With the development of thinning and miniaturization of electronic equipment, the width of PCB board is very small. In order to save space utilization, under normal circumstances, the QR code marked on the PCB board is very small. The marking of two-dimensional codes with small density and format can only be realized by the laser marking technology of laser marking machines. Such small-format two-dimensional codes can reach the precision of 1x1mm.

After knowing how to buy a laser marking machine, do our customers know how to maintain a valuable equipment?

1. When the light pen of the laser marking machine is in operation, it must not touch the beam;

2. The field lens will become blurred or dusty after working for a long time. At this time, use a clean absorbent cotton dipped in alcohol to gently wipe the lower surface of the lens;

3. During operation, once the end pump laser marking machine fails, it needs to be stopped immediately to avoid personal injury;

4. Do not touch the lens of the device with your hands or other objects;

5. The laser is the core of a laser marking machine. It must be moved carefully to avoid being broken due to improper movement;

6. Do not start the laser marking machine when the water circulation is improper;

7. Water replacement and water tank cleaning: clean and replace the water inside once a week. The circulating water inside is not good for the machine for too long. The water quality and water temperature of the circulating water directly affect the service life of the laser tube. It is recommended to use pure water. Keep the water temperature below 35°C.
