The influence of laser marking machine on PCB circuit board
Jun 25,2021
The advantages of QR code laser marking machine in the PCB circuit board industry have been vividly embodied. QR codes have the advantages of good quality, high efficiency, sustainable marking, high consistency, low cost, and reliability. With the continuous development of smart phone technology and wearable electronic technology, intelligence, lightweight and miniaturization have become the mainstream. Consumers are increasingly demanding product quality. What is the role of QR code laser marking machine in the processing field?
Therefore, how to achieve PCB quality control requires a traceability system for product quality. The commonly used method is to mark the character string, one-dimensional code, QR code and other information on the PCB through laser marking technology, and upload it to The database automatically excludes unqualified products, and realizes tracking from supplier information to product outbound data, tracking the whole process, product quality, and effectively realizing automatic production control of products.
With the development of light weight and miniaturization of electronic equipment, the format of the PCB board is very small. In order to save space, the QR code marked on the PCB is usually very small, such as a 2x2mm QR code, which contains more than 20 characters of information. This kind of high-density, small QR code marking can only be achieved by PCB laser marking machine technology.
Compared with inkjet, PCB laser marking technology is more environmentally friendly and economical, permanent marking is not easy to erase, non-contact and non-destructive marking, will not cause damage to the substrate, high processing accuracy, long service life, continuous working time of more than 100,000 Hours, the processing efficiency is fast, the QR code completion time is less than 1 second, the hand feel is not obvious, the manual operation is simple, and the stupid processing is performed.
By comparing the advantages and disadvantages of laser marking technology and inkjet marking technology, it can be seen that the combination of a new generation of printed circuit board QR code marks and laser technology is the new generation of QR code marks and laser technology
As a partner, the PCB laser marking machine helps the printed board industry complete perfect quality control. The vast PCB board market provides a broad development space for the laser marking machine industry.
