Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 通常の印刷配線用電子部品を基板上に装着で きる程度の堅牢さを有し、かつ、量産性に富み、薄形化 された基板トランス及びその製造方法の提供。 【構成】 フェライト単体または磁性金属箔を積層した 比較的堅牢な基板1と、基板1に設けた複数対のスルー ホール2 1 乃至2 n 、3 1 乃至3 n と、基板1の両表面 に形成され、かつ、対応するスルーホール2 1 乃至 2 n 、3 1 乃至3 n 間をそれぞれ結合した複数条の印刷 配線導体4 1 乃至4 n-1 、5 1 乃至5 n-1 とを備え、ス ルーホール2 1 乃至2 n 、3 1 乃至3 n を介して電気的 に直列結合された複数条の印刷配線導体4 1 乃至 4 n-1 、5 1 乃至5 n-1 により一対のコイル巻線が形成 される。前記一対のコイル巻線は、磁性体基板1に実質 的に巻回されているので、小型で、薄型の、堅牢な基板 トランスを得ることができ、しかも、この基板トランス は、通常の厚膜印刷配線とほぼ同じ製造工程で製造され る。 (57) [Summary] [Purpose] To provide a thinned board transformer and a manufacturing method thereof, which is robust enough to mount an ordinary electronic component for printed wiring on a board and has high mass productivity. . [Structure] A relatively robust substrate 1 in which a single ferrite or magnetic metal foil is laminated, a plurality of pairs of through holes 2 1 to 2 n , 3 1 to 3 n provided in the substrate 1, and formed on both surfaces of the substrate 1. And a plurality of printed wiring conductors 4 1 to 4 n-1 and 5 1 to 5 n-1 in which corresponding through holes 2 1 to 2 n and 3 1 to 3 n are respectively coupled, A plurality of printed wiring conductors 4 1 to 4 n-1 and 5 1 to 5 n-1 electrically connected in series through the holes 2 1 to 2 n and 3 1 to 3 n form a pair of coil windings. It is formed. Since the pair of coil windings are substantially wound around the magnetic substrate 1, a compact, thin, and robust substrate transformer can be obtained. It is manufactured in almost the same manufacturing process as the printed wiring.
