[0002] At present, professional circuit board manufacturers use large-scale CNC processing equipment to drill circuit boards. This large-scale drilling equipment is basically imported equipment, and the price is as high as hundreds of thousands. Universities and general electronic product R&D and production enterprises and scientific research institutes cannot bear the high price. Drilling equipment; At present, domestic universities, electronic-related product research and development companies, and scientific research institutes are using a large number of methods such as thermal transfer printing and exposure board manufacturing to make PCB prototypes and small batch production. This method solves the problem in professional circuit board manufacturing. The cost of making prototypes in the board factory is high and the cycle is long. However, since the thermal transfer equipment and the exposure board making equipment can only complete part of the work of the rapid board making, the circuit board drilling is a very important task in the rapid board making process. , but due to the high price of existing large-scale CNC drilling equipment, colleges and scientific research enterprises have adopted cheap manual micro-drills to drill holes, but manual micro-drills have several obvious defects: manual positioning is not accurate, The efficiency of drilling is extremely low and the drill bit is easy to break. Therefore, how to achieve low-cost, high-efficiency, and high-precision drilling has become a bottleneck problem for rapid board manufacturing
