Abstract:
1. An inspection device for inspecting electrical characteristics of a power device having terminals on its top surface and bottom surface, the inspection device comprising: a support plate for mounting thereon a chip in which the power device is formed; a positioning member for positioning the chip mounted on the support plate; a metal film formed on a surface of the support plate in a range from an area on which the chip is mounted to an area on which the chip is not mounted; a probe pin configured to be brought into contact with the metal film in the area on which the chip is not mounted; and a fritting probe pin making a pair with the probe pin, which is in contact with the metal film together with the probe pin and electrically conducts the probe pin to the metal film by utilizing a fitting phenomenon, wherein the metal film in the area on which the chip is not mounted makes it possible to electrically conduct the probe pin with the terminal on the bottom surface of the power device when the probe pin is brought into contact with the metal film in the area on which the chip is not mounted.
