PCB드릴링용 공기베어링 스핀들의 런아웃(RunOut)에 따른 가공 홀의 형상변화
Drilled Hole Variation of Air Bearing Spindle for PCB according to RUNOUT
초록
In this study, we measured cylindricity and Runout of the air bearing spindle, and tested PCB(printed circuit boards) drilling with 0.4mm micro drill at 90,000rpm and 110,000rpm in order to obtain drilling hole error. Results are as follows; The air bearing spindle's Runout was not so high within
