Abstract
It is proposed that more and more demands to the electron manufacturing manufacturing industry and PCBs profession. The PCBs numerical controlled drill machine development tendency that faces high speed, high accuracy, high dependability, intelligentization, flexibleization and integrationization is more and more obvious. Currently, high-precision high-speed catalysis PCBs numerical controlled drill machine is constrained and influenced the level of China's electronics manufacturing industry and the electronic information infrastructure capacity is an important element of our electronic manufacturing gap with the world's advanced level of one of the important links. Thus, high-precision high-speed PCBs numerical controlled drill machine research and application of key technologies to improve and enhance the overall performance of PCBs numerical controlled drill machine for electronic manufacturing processes and equipment to improve our level of self-supporting capacity of the manufacturing sector and electronic information will be of practical significance. This paper systematically introduces the composition and principle of a self-design and manufactured miniature NC drill machine and control system used for processing printing circuit board. It analyzes the function of every part, especially for the specific application and expandability of MCS-51 single chip processors. The result possesses value.
