摘　　要：随着5G通信技术的飞速发展,通信背板朝着多层数、高厚度、小孔径的趋势发展,故开发超高长径比的微钻是一个亟待解决的问题。因此,我公司专门设计一款高长径比的钻针,分别从材料、结构、涂层以及制备工艺等角度来阐述,并结合试验来验证钻针的高可靠稳定性。With the rapid development of 5G communication technology,the communication backplane board is developing towards the trend of multiple layers,high thickness and small hole size.Therefore,the development of ultra-high aspect ratio micro drill is an urgent problem to be solved.Therefore,our company has specially designed a high aspect ratio drill bit.This paper expounds the design of the drill bit from the perspectives of material,structure,coating and preparation process,and verifies the high reliability and stability of the drill bit combined with experiments.
