背钻技术的能力提升研究

Research on Improving Backdrilling Technique Ability

背钻是通过二次机械钻孔的方式,将不利于信号传输的孔铜去除,背钻后残留的Stub长度越短,对信号传输的完整性越有利。文章主要研究了小孔背钻的过程能力优化以及高对准度背钻控制方法,实现背钻孔的堵孔改善及对准度提升。

Backdrilling is a process of removing stubs of drilled holes that may negatively affect signal transmission by performing secondary mechanical drilling.The shorter the residual stub length after backdrilling,the better the signal transmission integrity.This paper focuses on optimizing the process capability of small hole backdrilling and proposing a high-precision alignment control method to improve backdrilling hole plugging and alignment accuracy.
