Laser marking technology replaces screen printing

Keeping up with the pace of the Industry 4.0 era, laser marking is also constantly making breakthroughs, gradually replacing traditional screen printing processing, and bringing new vitality to the manufacturing industry in a more convenient way. Among them, the development of related industries represented by PCB circuit boards is especially inseparable from the innovative application of laser marking. The accuracy and flexibility of laser marking make up for the lack of silk screen processing, and has gradually become the most important part of PCB marking. The best processing tools have always played a pivotal role in the circuit board industry. Laser laser marking machine, Yantai laser marking machine, Rizhao laser marking machine have done a good job in this regard.

PCB board, as one of the most important components in the contemporary electronic component industry, is applied to almost all electronic products, known as: ' The mother of electronic system products'. With the continuous development of smart phone technology and wearable electronic technology, intelligence, thinning and miniaturization have become the mainstream, and manufacturers have become more and more strict with the production requirements of PCB circuit boards in these electronic products. In order to better achieve product quality information control, information traceability systems such as marking characters, barcodes, and QR codes on PCB boards have emerged as the times require.

Traditional silk screen printing process, using the prepared graphic screen, using external pressure to make the character ink penetrate through some meshes of the screen, and miss printing on the surface of the circuit board. The rest of the meshes on the screen will be blocked, and the ink will not penetrate, and only blanks will be formed on the surface of the circuit board. The missing ink will form text, logos, patterns, etc. This processing method is relatively cheap and fast, but it has the disadvantages of rough marking effect, easy falling off of markings, inability to mark PCB boards with small format, and certain toxicity of chemical raw materials.

Laser marking uses a high-energy-density laser to locally irradiate the PCB board to vaporize or discolor the surface material, thereby leaving a permanent mark. This non-contact processing can mark a very clear QR code on a very small format, ensuring high precision and high quality. At the same time, the laser marking will not be worn due to high and low temperature, acid-base changes and external friction, and does not require chemical assistance, and has no negative effect on personnel safety and the environment.
