Features and advantages of PCB laser marking machine [Copy link]

People also have high requirements for product appearance and performance. Intelligence, lightness, and miniaturization have become the mainstream, which has increasingly stringent requirements for PCB manufacturers. 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, and these PCB laser marking machines can clearly mark them.

The traditional silk-screen processing method is to use a prepared graphic screen, use external pressure to penetrate from the mesh, and leak print on the surface of the circuit board, only forming a blank on the surface of the circuit board, and the ink leaked forms text, logos, patterns, etc. This processing method is relatively cheap, but the marking effect is rough, it is easy to fall off, it cannot mark PCB boards with smaller formats, and the chemical raw materials have certain toxicity. Laser marking uses laser to partially irradiate the PCB board to vaporize or discolor the surface material, leaving a permanent mark. This non-contact processing can mark a very clear QR code on a very small format, ensuring high precision while also ensuring high quality. Usually, PCB marking machines use cold light marking, which will not generate high temperature, nor will it cause acid-base changes and external friction to cause wear on the surface of PCB components. It does not require chemical assistance and has no negative effects on personnel safety and the environment. (http://a13530218066.51sole.com/)

The industrial era is constantly developing towards a more high-tech industrialization, and PCB laser marking machines are also making breakthroughs, gradually replacing traditional silk-screen processing, and bringing new vitality to the manufacturing industry in a more convenient way. PCB is one of the important components in the contemporary electronic component industry, and is almost used in most electronic products, and the PCB board industry is also widely used in laser marking machines. PCB-specific laser marking machines have better accuracy and flexibility, can make up for the shortcomings of silk-screen processing, greatly improve production 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.
