Abstract:
1. A capacitor inspection device for testing the electrical characteristics of solid electrolytic capacitors, the device comprising: a substrate made of an insulating material; a first conductor unit that makes electrical contact with an anode of a solid electrolytic capacitor, and a second conductor unit that makes electrical contact with a cathode of the solid electrolytic capacitor, the first and second conductor unit being provided on a same plane of the substrate as conductor patterns, wherein a first protruding part is provided on an upper surface of the first conductor unit such that an upper surface of the first protruding part is above the upper surface of the first conductor unit, and the second protruding part is provided on an upper surface of the second conductor unit such that an upper surface of the second protruding part is above the upper surface of the second conductor unit and is at a same height as the upper surface of the first protruding part; first and second conductive sheets each having an elastic property, the first conductive sheet contacting an inferior surface of the anode of the solid electrolytic capacitor and the second conductive sheet contacting an inferior surface of the cathode of the solid electrolytic capacitor, a network analyzer having an input port and an output port; a signal input unit attached to the substrate and coupled with the input port; a signal output unit attached to the substrate and coupled with the output port; and a pressurizing unit that presses the anode of the solid electrolytic capacitor to make electrical contact with the first protruding part of the first conductor unit via the first conductive sheet and that presses the cathode of the capacitor to make electrical contact with the second protruding part of the second conductor unit via the second conductive sheet.
