Abstract: A calibration board and a timing calibration method thereof are provided. The calibration board for calibrating signal delays of test channels in an automatic test equipment is pluggably disposed in the automatic test equipment and includes calibration groups, a first common node, and a switching module. Each calibration group includes a second common node and conductive pads electrically connecting to the second common node. Each conductive pad selectively and electrically connects to one test channel. The switching module electrically connects to the first common node and each second common node. When a first delay calibration procedure is performed, the connection between the first common node and each second common node is disabled. When a second delay calibration procedure is performed, the connection between the first common node and each second common node is built.
