In electronics manufacturing, an Excellon file is a text-based file format which is used to control the actions of a CNC drilling machine, commonly used in the drilling of printed circuit boards (PCBs).
The Excellon file format is a variant of standard RS-274C. It consists of commands to instruct a CNC drilling machine to drill holes of specific diameters at specific locations on a PCB.
The name Excellon comes from the Excellon Automation Company, founded in Torrance, California, USA in 1963 by inventor Joseph Smith.
