Title:
EQUIPMENT AND METHOD FOR INSPECTING CAPACITOR
Document Type and Number:
Japanese Patent JP3932793
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve a problem that a low ESR capacitor of 100 mΩ or less can not be inspected sufficiently because of high total impedance of an inspection circuit, and a problem that a stabilized inspection can not be ensured due to variation in the characteristics of a sample because of the lack of a circuit for controlling the applied current and to provide controlled equipment and method for inspecting and sorting low ESR capacitors at a high rate.
SOLUTION: An inspection circuit part comprising a charging circuit and a discharging circuit is arranged on the same plane, a plurality of power supply capacitors 2 are arranged in the direction intersecting the plane of the inspection circuit part and connected in parallel and then they are arranged integrally so that a low ESR capacitor can be provided with a sufficiently large current and a current stress having a sufficiently quick response under conditions optimal for the rating of the capacitor.
