摘　　要：在各类汽车上使用77 GHz雷达系统已成为现实,市场正在快速成长。目前被市场广泛认可的应用在77 GHz汽车雷达的覆铜板基材主要是PTFE+陶瓷粉填充的产品,但其可加工性能较差,存在较多的PCB加工结构性问题,给PCB加工带来困扰。本文通过对PTFE材料的加工失效模式进行了分析研究,提出了相应加工解决方案。It has become a reality to use 77 GHz radar system in all kinds of vehicles.The market of 77GHz MMW radar is growing rapidly.At present,the copper clad laminate(CCL)substrates widely recognized by the market for 77GHz automotive radar are mainly PTFE+ceramic powder filled products,but their processability is often poor.As a result,there are many structural problems in PCB processing,which brings trouble to PCB processing.In this paper,the processing failure modes of PTFE materials are analyzed,and the corresponding processing solutions are put forward.
