在合适的稳定条件下,在大多数材料下机械钻孔可以形成0.08mm(0.003″)的孔径,关键是如何掌握和改进机械振动特性。1 前言 随着电子产品小型化而要求更小的导通孔化,但却受到了常规钻孔机械性能的限制。为了在常规钻机达到精确控制精度误差,必须克服其不稳定性或不经济性或者两者兼之的问题,否则当采用更小钻头时,会增加钻头的破断。 采用常规钻孔机来形成小孔的内在困难是 Under the proper stable conditions, mechanical drilling can form a 0.08mm (0.003 ") hole under most materials, the key is how to master and improve the mechanical vibration characteristics .1 Foreword With the miniaturization of electronic products requires a smaller guide Through-hole, but subject to the limitations of conventional drilling mechanical properties In order to achieve precision precision control accuracy of conventional drilling rig, you must overcome its instability or uneconomical or both, or when using a smaller drill , Will increase the drill bit rupture. The use of conventional drilling machine to form a small hole inherent difficulty is
