PCB (Printed Circuit Board), the Chinese name is “printed circuit board”, is a carrier for interconnecting electronic components and electrical appliances, and exists in almost every electronic device. Continuous breakthroughs in PCB laser marking technology, rapid and clear marking of QR codes, barcodes, characters and other information on PCB boards with densely dispersed materials and different materials, helping electronic products to move towards lightweight, quantification and precision in the field of precision marking , Intelligent development.

Disadvantages of the traditional ink screen printing method of PCB

With the rapid development of the intelligent process of the 3C electronics industry, the number and materials of internal components are also increasing, and the volume is getting smaller and smaller. Processing requirements are becoming more and more stringent. The traditional ink screen printing process is easy to fade and fall off, the processing process is particularly cumbersome, the efficiency is low, and the labor cost is high. In addition, ink, as a chemical printing and dyeing substance, has a strong odor, long-term use is not conducive to health, and does not meet the requirements of environmental protection policies.

Advantages of PCB laser marking process

The principle of the PCB laser marking process is to use a high-energy beam to non-contact irradiate the workpiece to quickly complete the marking instructions without any medium, and can be marked on any different surface. The PCB laser marking process has fast speed, high precision, stable performance, small thermal influence, and no deformation due to internal stress of the workpiece. Any complex graphics can be marked, and the marking after marking is clear and highly recognizable. , the edges are smooth and delicate, reflecting the timeless aesthetic value and high-end technology sense.

The PCB laser marking process uses light as the “knife” and uses a very fine high-energy beam focusing spot for non-contact processing without any mechanical pressure or mechanical stress, and will not cause any damage to the workpiece. The PCB laser marking process can complete some precision machining processes that cannot be achieved by traditional and conventional methods.

In addition, the PCB laser marking process does not require any additional auxiliary equipment and materials. One piece of equipment can meet the marking process requirements of any material and shape components of PCB. The equipment has high stability and is suitable for long-term uninterrupted work. , PCB laser marking process has the advantages of low cost, high efficiency, high precision and high production capacity, which have been selected by more and more PCB printed circuit board manufacturers.
