INDUKTOR MED FLERE VINDINGER OG FREMGANGSMADE TIL FREMSTILLING AF SAMME

摘要

A method of constructing an inductive-capacitive (LC) network is disclosed in which a predetermined pattern is cut from a metallic sheet to provide a multi-turn, essentially spiral-like configuration in which a plurality of interconnecting regions are left between adjacent turns. A pre-laminate is then formed by laminating one surface of the configured sheet to a surface of a sheet of dielectric material. A completed multi-turn inductor is formed by a second cutting operation in which the remaining interconnecting regions between the adjacent turns are removed. The LC network is completed by laminating a second metallic sheet to a dielectric layer overlying the completed multi-turn inductor. The first and second cutting operations and assembly of the respective sheets are performed such that any burrs resulting from the operations are directed away from the interlying sheet of dielectric material, thereby avoiding problems due to shorting out between the two metallic sheets.
