PCB laser marking machine helps PCB industry develop rapidly

       PCB, as an important component in the current electronic field, has an important influence on the development of the electronics industry. In order to better control the production process of many PCBs in the PCB production process, it is necessary to mark information on the PCB board, such as production batches, characters, barcodes and other information. In order to play an important role, the PCB laser marking machine is one of the processing solutions that have been played. Whether it is fine processing, processing efficiency, and processing effects, it fully meets the needs of the current PCB marking processing.




       The traceability marking process on the PCB board mainly includes screen printing and laser marking. Among them, silk printing has problems such as easy to fall off, easy to remove, rough marks, and environmental pollution. In addition, portable electronic products are increasingly developing in the direction of miniaturization, high integration, and portability. The pads and spacing are getting smaller and smaller, making printing alignment more difficult. The PCB laser marking machine can remove the surface material of the object point by point. Its advanced nature is that the marking process is non-contact processing, which does not produce mechanical extrusion or mechanical stress, so it will not damage the processed object; due to the size of the laser focus It is small, the heat affected area is small, and the processing is fine, which can overcome the technical defects that the traditional processing method is easy to fall off and the processing accuracy is not high.
       Laser marking processing, as a high-tech means of marking processing, has advantages unmatched by traditional processing methods. Unlike traditional processing methods, PCB laser marking uses high-energy density laser to irradiate the workpiece locally to make the surface material A marking method that vaporizes or undergoes a chemical reaction that changes color, leaving a permanent mark. PCB laser marking machine can print all kinds of text, symbols and patterns, etc., the character size can be from millimeters to microns. This can effectively prevent the counterfeit of the product, and plays an important role in the PCB board industry.
