尽管激光钻孔在印制板（PCB）钻孔中应用得越来越广，但是利用微型钻头在机械钻机上进行的机械钻孔仍然是最重要的PCB钻孔方式。顺应PCB微孔的发展趋势，微型钻头直径越来越小，新型钻头结构不断出现，微钻头性能不断提高，微钻头涂层技术逐步成熟，微孔钻削的研究不断深入，推动着PCB技术的发展。本文即对微钻头及微孔钻削的进展进行总结，对微钻头和微孔钻削的趋势进行展望。

Although laser drilling plays more and more important role in PCB microvia drilling, mechanical drilling by using micro drill bit on drilling machine still dominates the PCB micro hole drilling methods. With the development trend of PCB micro hole, the micro drill bit becomes smaller and smaller, the performances of micro drill bit becomes better and better, coated micro drill bits becomes more and more popular and the comprehensive studies of micro hole drilling are reported. These developments are reviewed in this paper and the development trend of micro drill bit and micro drilling are pointed.
