Inductor device for integrated circuit

Abstract

Abstract PURPOSE:To facilitate adjustment by a method wherein an inductor is formed on an insulating fitting plate, which can be broken off in rectangular shapes along edge sides, in a square and spiral shape, rectangles are broken off, and the inductor is adjusted and mounted on to an insulating substrate. CONSTITUTION:An inductor 12 is made up in such a manner that Au, etc. are printed on a fitting plate 11 in ceramics in a square and spiral shape. Each side of the inductor 12 passes in rectangles with notches 11a on the back of the fitting plate 11. The fitting plate 11 is successively broken off from the rectangules of end edges, the sides of the inductor 12 are removed with the rectangles, the inductor is adjusted to necessary inductance value, and the inductor is installed onto a substrate for IC and connected to the wiring 13 of the substrate. According to this constitution, the inductor can simply be adjusted, and a cheap and high reliability IC can be obtained.
