Research on Design Points of Semiconductor Lighting Driven PCB

摘要

In this paper, the design points of a kind of semiconductor lighting driven PCB are studied. With the development of semiconductor technology, the market demand of PCB has been improved rapidly. The processing quality of PCB is constantly upgrading, and its online detection accuracy and speed requirements are also improving. Improving the passing rate of products has become an important means to enhance the market competitiveness of enterprises. Because foreign PCB products are expensive, China's PCB high-end detection products are few, so the quality of PCB products in China is limited. PCB photoelectric inspection machine is a highly intelligent PCB drilling automatic testing equipment. The equipment provides two standard information making methods; it can automatically report a variety of defects in the PCB drilling; it has high detection precision and very fast processing speed. It can make a comprehensive test for each PCB hole out of the factory. Based on the principle of modularity, low cost and high performance, the design and implementation of the PCB photoelectric inspection machine system are carried out in this paper.
