Purchasing characteristics and advantages of PCB laser marking machine
People also have high requirements in terms of product appearance and performance. Intelligence, lightness, thinness, and miniaturization have become the mainstream, which puts more and more stringent requirements on PCB circuit boardmanufacturers. In order to better achieve product quality information management and control, information traceability systems such as marking characters, barcodes, and two-dimensional codes on PCB boards have emerged, and these PCB laser marking machines can be clearly marked.

The traditional silk-screen printing process is to use a good graphic screen, use external pressure to penetrate through the mesh, and miss to print on the surface of the circuit board, only forming a blank on the surface of the circuit board, and the missing ink forms the text and logo, Patterns, etc. This processing method is relatively cheap, but the marking effect is rough, it is easy to fall off, it is impossible to mark PCB boards with a small format, and the chemical raw materials have certain disadvantages such as toxicity. Laser marking machine marking is to use laser to locally irradiate the PCB board to vaporize or discolor the surface material, thereby leaving a permanent mark. This kind of non-contact processing can mark a very clear two-dimensional code on a very small format, ensuring high precision and high quality. Usually, PCB marking machines use cold light markings, which will not generate high temperature, will not cause acid and alkali changes and external friction to cause wear on the surface of PCB components. It does not require chemical assistance, which is both safe for personnel and the environment. No negative effects.

The industrial age is constantly developing towards more high-tech industrialization, and the PCB laser marking machine is also achieving breakthroughs, gradually replacing the traditional silk screen processing, and bringing new vitality to the manufacturing industry in a more convenient way. The PCB is one of the important components in the contemporary electronic component industry, almost applied to most electronic products, and the PCB board industry is also widely used in laser marking machine marking. PCB special laser marking machine has 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.
