ABSTRACT:
A method and apparatus for increasing the speed and efficiency of a drilling machine during the drilling of holes in printed circuit boards includes automatically setting a dwell time according to one or more predefined drilling parameters. A plurality of dwell times which vary in accordance with the predefined parameters are stored in a computer memory device. A drilling machine controller automatically selects an optimal dwell time from the memory device according to the drilling conditions of a particular drilling operation so that the shortest feasible dwell time is used for obtaining a desired degree of hole placement accuracy and hole quality for the drilling operation. The apparatus is a drilling machine system that includes a controller which contains dwell times that vary in accordance with the diameter of a drill tool.
