Purchasing characteristics and advantages of pcb laser marking machine

The traditional silk screen processing method 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 a blank is formed on the surface of the circuit board, and the missing ink forms characters and logos. , 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 PCBs 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 non-contact processing can mark a very clear two-dimensional code on a very small format, ensuring high accuracy 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.
