Embodiment Construction

[0051] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0052] 5A and B are exploded perspective views showing the steps of manufacturing planar magnetic products according to the manufacturing method of the multilayer printed coil substrate of the present invention. It is necessary to manufacture and prepare multiple sets of several types of printed coil substrates. The several types of printed coil substrates are formed by forming coils with different numbers of windings (number of turns) in conductor patterns on one or both sides of an insulating substrate. In order to obtain certain characteristics of the planar magnetic product to be manufactured, a plurality of (five in this example) printed coil substrates 1a, 1b, 1c, 1d, and 1e are selected from these printed coil substrates. Also, as shown in FIG. 5A, the selected printed coil substrates 1a, 1b, 1c, 1d, and 1e are laminated. 11 and 12 are magnetic cores f...

Abstract

A printed coil component has a printed coil substrate with a coil formed in one or more layers of conductor patterns, and the printed coil substrate can be electrically connected to the printed coil substrate; A hole is provided on the insulating base and a terminal pin electrically connected to the external conductor is passed through the through hole, and the terminal pin is electrically connected to the through hole.

Description

[0001] This application is a divisional application with an application date of June 21, 1995, an application number of 95107394.x, and a title of "Manufacturing Method of Multilayer Printed Coil Substrate, Printed Coil Component and Printed Coil Substrate". technical field [0002] The present invention relates to a multilayer printed coil component having one or more printed coil substrates for planar magnetic products. Background technique [0003] For magnetic products used in transformers and reactance coils used in electronic circuits such as switching power supplies, conventionally wound linear magnetic products have generally been used. Wire-wound magnetic products are constructed by winding electric wires such as enameled wires on a reel equipped with lead terminals. In addition, this wire-wound magnetic product is easy to manufacture because circuit technicians can easily change the number of coil winding turns an...
