PCB微孔高速钻床中空气轴承的应用研究

The application research of air bearing on high-speed drilling press with PCB micro-porous

介绍高密度PCB的微孔钻削。基于PCB材料的热学特性、机械性能和可加工性。针对印制电路板上的钻孔阻力不恒定、转轴高速振动、钻孔数量大和刀具折损等问题。研究和实践应用空气轴承的优势,并取得较好效果。从而促进高密度多层PCB高效高速的发展。

Drilling with the high density PCB micro-porous, it is based on the thermal, mechanical and workability characteristics of PCB material. With those problem of resistance of drilling on printed board varied, the shaft vibrating at high-speed, a great number of drilling holes, and tool destroyed, it has advantage in researching and applying air bearing, and has better effect. Thus help the developments of high density stacking PCB rapidly and efficiently.
