Abstract
PURPOSE:To elucidate the state of corrosion of the main body of a resin- package-type electronic component without exfoliating resin, by a method wherein the opposite end electrodes of a circular conductive pattern formed coaxially on the surface of the main body of the component are connected to leads respectively. CONSTITUTION:A central lead 3a of a lead 3 is joined at one end to a heat- radiating plate 1, while leads 3b and 3c are disposed at one end near the main body 2 of a component respectively. Circular conductive patterns 2a and 2b having ends are formed on the surface of the main body 2 of this component, and the patterns are connected commonly at one end to an electrode 2c, while connected at the other end to electrodes 2d and 2e respectively. Besides, the electrode 2c and the lead 3a are connected together by a metal fine wire 4a, the electrode 2d and the lead 3b by a metal fine were 4b, and the electrode 2e and the lead 3c by a metal fine were 4c, respectively. By checking the continuities between the leads 3a and 3b and between the leads 3a and 3c in the course of PCT (Pressure Cooker Test), it can be determined that the patterns 2a and 2b and the fine wires 4a-4c are disconnected, and a state of permeation of moisture can be discriminated.
