Publication number: 20230213567Abstract: A mount board has a plurality of terminals electrically connected to a plurality of pins of a semiconductor device, and a conductor pattern. An electrostatic withstand voltage test device includes a metal plate on which the mount board is installed, a power supply for applying a voltage to the metal plate, an insulator disposed between the metal plate and the mount board, a switch circuit connected between the terminals and ground wiring, and a controller for controlling the switch circuit. The switch circuit includes a plurality of first switches provided corresponding to the terminals and each connecting a corresponding terminal to the ground wiring. The controller turns on at least one first switch selected from the first switches when an electric charge stored in the conductor pattern is discharged to the ground wiring through the semiconductor device.Type: ApplicationFiled: June 30, 2021Publication date: July 6, 2023Applicant: Mitsubishi Electric CorporationInventors: Kohei NAKANISHI, Masao KANATANI, Shinichiro ANDO
