Abstract

PURPOSE:To reduce magnetic resistance, and to obtain high Q by interposing an insulating layer made of a nonmagnetic material between conductor patterns. CONSTITUTION:Conductor patterns 14 are formed into a magnetic material 13, and the patterns 14 form wound coil patterns. The insulating layers 15 made of the nonmagnetic material are formed among the patterns 14. The insulating layer 15 is formed by the nonmagnetic material, such as alumina, steatite, Si dioxide, etc., and it is preferable that the permittivities of these conductors are lowered. According to such constitution, a magnetic circuit is formed in the magnetic material, and is difficult to be formed to sections among conductors. Consequently, since the reluctance of the conductors reduces, the resistance of the wound conductor patterns also minimizes, and Q value can be improved.

Inductance elements have long been used as coiled conductive wires, but in order to increase inductance, magnetic cores such as ferrite cores are also used. However, with the miniaturization of electronic circuits, the demand for miniaturization of electronic components has also increased, and inductance elements are no exception. Compact inductance elements Although they are behind compared to other elements, development is proceeding in two main directions. One is basically to reduce the size and shape of a conventional inductance element, and the other is to solidify it by a printing method or the like.

In an inductance element that forms a circulating conductive pattern by printing, the area around the conductive pattern must be an insulator, and in order to increase the inductance value, it is preferably a magnetic material. So 1. In general, those in which conductive patterns and insulating magnetic layers are alternately printed are often used. In the inductance element formed in this manner, a magnetic layer exists between adjacent conductive patterns. Also, since the direction of the current is the same, as shown in FIG.
2 will occur. As a result, the direction of the lines of magnetic force becomes opposite between the two conductive turns 11, so that the magnetic resistance increases. This is,

FIG. 3 is a front sectional view showing an example of the method for manufacturing an inductance element according to the present invention. Ferrite 17 is printed on the substrate 16 by kneading the powder with a binder such as methylcellulose or butyral resin and a solvent to form a paste (c. At this time, ferrite 17 is printed on the other parts except for the part where the conductive pattern will be formed later). Print.Due to the cracking, the area where the conductive pattern is printed becomes the groove portion formed by the ferrite 17.

Next, a paste-like conductor 18 made of a silver-palladium alloy, a binder, and a solvent is printed. It is best to carry out this printing in two stages. First, print to fill the grooves formed by the ferrite 17, and then print with the same pattern to a similar thickness to match the thickness of the ferrite 17. Make sure it is about twice the size (B). Even if the conductor 18 shrinks due to sintering due to the cracking, a conductive circuit pattern with a sufficient thickness can be formed.
