| Research Abstract |
This study dealt with micro-drilling, less than diameter 200 micron, with an ultra-high speed spindle, more than sixteen thousand rpm, in the high density LSI printed wiring boards. In order to achieve the high efficiency in this kind of micro drilling, it was effective to apply the time scale TSP (travelling salesman problem) considering the acceleration of the feed drive on the determination of the drilling order. Moreover, the suitable drilling condition was found out by monitoring the temperature around the drilled hole considering the thermal storage. As a result, the proposed methods are found out to be effective for a novel high speed drilling CAM system, and make it possible to conduct the high speed and quality micro-drilling in the high density printed wiring boards.
