摘要

Purpose - To provide a solution for PCB drilling with strict requirements on hole wall quality. Design/methodology/approach - The influential mechanism of key micro drill bit parameters on hole wall roughness is analyzed. A new type of micro drill bit is developed on the basis of theoretical analysis and experimental verifications. Findings - The key factors in drill bit design which can enable superior hole wall quality are described. Experimental results show that very good hole wall quality is achieved by such newly developed drill bits. Meanwhile, the new drill bits show good performance in terms of wear-resistance and hole registration accuracy. A solution for PCB drilling with strict requirements on hole wall quality is provided. Originality/value - The paper highlights the influential mechanism of key parameters of micro drill bit design on the hole wall quality of PCBs. A new kind of micro drill bit which can achieve superior hole wall quality has been developed.
