With the arrival of intelligent driving and 5th generation, applications of ceramic filled PCBs are increasing. Yet the ceramic particles filled could cause very severe wear for the drill bit, so the uncoated bit can only process hundreds or even dozens of holes with unguaranteed quality. Jinzhou, as the leader of PCB tools’ industry, has very mature solutions for ceramic filled PCBs, we highly recommend SHD coated series for you.
The main advantage of SHD coating is that its hardness is very high, which is more than 80 GPA, so it has excellent wear resisting property, long processing life and outstanding processing quality. SHD coating is highly recommended for processing high-frequency or high-thermal ceramic filled boards, such as 92ML、4350B、AD300C、TC350 、ST115D and so on.
Processing Life
The processing life of coated drill bit reaches 12000 holes, which is 60 times than that of uncoated drill bits with processing life only 200 holes.
02
Wearing
Uncoated drill bits wear a lot after 200 holes, yet coated drill bits wear just a little bit after 12000 holes, please see the following:
03
Hole Wall Quality
The hole wall roughness of uncoated drill bits after 200 holes is 37.97μm, yet that of coated drill bits after 12000 holes is only 13.27μm, please see the following:
Conclusions
While processing ceramic filled PCBs, SHD coated drill bits maintain excellent wear-resisting property, long lifespan and outstanding quality, which can solve the processing difficulties of ceramic filled PCBs of PCB industry, is a real sharp tool for processing ceramic filled PCBs.
