Laser marking machines increase speed to help the circuit board industry
Laser marking machine is a processing method that uses high-energy laser to mark LOGO, text, characters, and symbols on products. It is a widely used processing method, compared to traditional pad printing and coding. It has the advantages of high efficiency, no ink pollution, and environmental protection.
In addition, as a non-contact processing, the laser has little effect on the data without deformation. Laser marking uses a high-energy laser to engrave the processing capacity on the product, so the processing capacity will not be lost casually. The laser marking machine has these advantages while the application is becoming more and more common, so how to improve the speed and efficiency of the laser marking machine in consumption.
The laser marking machine increases the laser marking speed: the laser marking speed is related to the performance of the galvanometer. Nowadays, the domestic galvanometer was very mature. The speed of the ordinary domestic digital galvanometer can reach 10000mm/s, and the normal speed is set to 5000mm/s was once fast. Of course, it must be changed under the condition that the laser marking effect is guaranteed.
Increase laser power: After the speed of the laser marking machine increases, the laser energy per unit area of ​​laser marking becomes smaller. If the laser marking effect is not diminished, the laser power needs to be increased.
The fiber laser is controlled by the percentage of laser control to control the UV laser marking mechanism. In order to extend the service life of the fiber laser, the general setting should not be greater than 80%. The end pump and semiconductor laser are adjusted according to the request of the laser power supply to increase the power supply.
Laser marking is a very advanced marking technology. After the focused laser carving technology, the characters and patterns that need to be marked are carved on the surface of the object. As the "mother of electronic products", the circuit board (PCB) is simply the upstream of consumer electronic products. Whether it is mobile phones, computers, tablets, display screens, etc., circuit boards are used, and their applications are widespread.
China is an important PCB consumer in the world, but the scope of end-pump laser marking machine companies is smaller than traditional powerhouses such as Japan and South Korea, and the industry concentration is low. Looking forward to the future of the domestic PCB industry, industry concentration will increase, and large-scale mass consumption has become the general trend. It is particularly important to stop standardization and mass management of PCB. The PCB board industry is also widely used in laser marking machine marking. PCB special laser marking machine has better accuracy and sensitivity, can compensate for the lack of silk screen processing, greatly improve consumption efficiency and yield, reduce costs, and reduce pollution. At present, it has been widely used in many fields such as digital products, wearable devices, and automotive circuit boards.
