Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chip type component for electronic components such as capacitors having polarities in electrodes.

[0002]

2. Description of the Related Art A conventional chip type component uses a non-magnetic material such as plastic as a molding material. In capacitors and the like having polarities in electrodes, the polarities are indicated by the printing on the surface of the molding material or the shape of the molding material (for example, JP-A 1-216516). In such a chip type component, the polarity inspection after mounting is performed by printing the molding material or visually observing the shape of the molding material.

[0003]

However, since the chip-shaped component itself is very small, such a visual inspection is extremely difficult, and not only the workability is bad but also an erroneous judgment is caused. Further, even in the case of automating the inspection, it is difficult to realize it because an extremely complicated device such as pattern recognition is required because it depends on visual observation. Such problems are becoming more and more serious due to the recent trend toward smaller electronic components.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a chip type component which can easily perform a polarity inspection after mounting an electronic component having a polarity on an electrode without visual inspection.

[0005]

A chip type component according to the present invention is made to achieve the above object,
It is provided with an electronic component having polarities in the electrodes, and a molding material which partially includes a magnetic body having magnetic poles corresponding to the polarities of the electrodes or a molding material which is entirely made of the magnetic bodies.

[0006]

The magnetic pole of the molding material corresponds to the polarity of the electrode of the electronic component. Therefore, if the polarities of the magnetic poles of the molding material are known, the polarities of the electrodes of the electronic component can be known.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described with reference to the drawings. FIG. 1 is a side view showing an embodiment of a chip type component according to the present invention.

The chip-type component 10 is provided with an electronic component 16 having polarities on the electrodes 12 and 14, and a molding material 18 made of a magnetic material having magnetic poles corresponding to the polarities of the electrodes 12 and 14.

The electronic component 16 is a capacitor in which the electrode 12 is a positive electrode and the electrode 14 is a negative electrode. The magnetic material forming the molding material 18 is the electrode 12 to the electrode 1 indicated by the arrow 20.
It is magnetized in the direction of 4. As a result, the electrode 12 side is S
The electrode 13 side is an N pole. Further, there is no problem even if the polarities of the magnetic poles are reversed.

As a result, when inspecting the polarities of the electrodes 12 and 14 after mounting, it is possible to inspect using a magnetic sensor such as a Hall element without relying on visual inspection.

In this embodiment, the molding material 18 is entirely made of a magnetic material.
It is obvious that the same is true when a part of the above is made of a magnetic material. Further, when the molding material 18 is entirely made of a magnetic material as in this embodiment, it goes without saying that the magnetic material is an insulating material such as ferrite.

[0012]

According to the chip-type component of the present invention, by forming all or part of the molding material with a magnetic material, the polarity inspection after mounting the electronic component can be performed with a magnetic sensor instead of visually. You can Therefore, automation can be easily realized, and erroneous mounting can be easily and accurately determined.
