PCB circuit board quality control

With the continuous advancement of science and technology, the continuous improvement of people's living standards, the continuous development of smart phone technology and wearable electronic technology, intelligence, thinness, and miniaturization have become the mainstream, and consumers will have higher and higher product quality requirements. Therefore, as a laser marking machine manufacturer, the quality control of the internal PCB circuit board is becoming more and more stringent. It must strive for excellence in order to win consumers, win the recognition of customers, and achieve secondary purchases, such as Apple, Huawei, etc. Technology leader.

PCB is one of the important components of the electronics industry. The output value of the industry accounts for about a quarter of the total output value of electronic components. It accounts for the largest proportion in the various electronic component sub-industries, and the flexible PCB board(ie FPC) is the growth in the PCB industry. One of the fastest sub-sectors. From the perspective of development trends in various regions of the world, after large-scale reorganization, migration and technology replacement, domestic PCB and FPC production and processing companies have seized the opportunity to transfer electronic products to the country, which has further increased the proportion of domestic circuit board output in the international market.

In order to better control the quality of products, it is necessary to record relevant production information to facilitate the full traceability and quality control of electronic products. The internal structure of the product-PCB marking information needs to be clear, and at the same time increase productivity and reduce costs in production. Reduce pollution and adapt to the development of multi-variety, small-batch production.

Identify string, one-dimensional code, two-dimensional code and other information on the PCB board, and upload it to the database through camera recognition, automatically reject unqualified products, and realize the product quality traceability of the entire internal process, from source supplier information to product delivery data Tracking, tracking the whole process, maximizing product quality, and effectively realizing the control of automatic production of products.

In order to better realize the management and control of many PCB boards in the product production process, marking information on PCB boards, such as production batches, characters, bar codes and other information, has become the development trend of the industry. Laser marking processing, as a high-tech means of marking processing, has advantages that traditional processing methods can’t match. Unlike traditional processing methods, laser processing uses high-energy-density lasers to locally irradiate the workpiece to vaporize or vaporize the surface material. A marking method in which a chemical reaction that changes color, leaving a permanent mark.

PCB laser marking machine is a special model specially used for marking bar codes, two-dimensional codes, characters, graphics and other information on printed circuit boards. It integrates high-performance UV/CO2/Fiber light source, high-pixel imported CCD camera, and micron-level mobile module to realize automatic positioning before coding and automatic reading and rating after coding.
