As electronic devices and products are being miniaturized, the printed wiring boards (PWBs) within them are also being miniaturized. Therefore, it is becoming increasingly difficult to decide the drilling conditions required for producing small-diameter and high-density holes. We have been focusing on drilling conditions recommended in drill catalogs and have been attempting to gather knowledge that drilling experts use to decide the drilling conditions. In this study, we classify drills using the relationship between the diameter and the flute length and hence show that the methods used for setting the cutting conditions are different in different regions of a PWB. In addition, by using a catalog of microdrills that use alloy steel as the work material, we discuss how unique drilling conditions can be set for PWBs.
