The effect of drilling speed and the chip load on the hole quality in a printed circuit board was investigated. The hole defects considered were smear, burr, nail heading and void. Holes drilled with different combinations of the speed and chip load were sectioned and examined using a scanning electron microscope to identify and quantify the defects. Each defect was related to the drilling variables in order to explain the reason for its formation and discuss the broad trends in the relationships.
