Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a polar chip type electronic component, and more particularly to a chip type electronic component in which the exterior of an electronic component element is covered with an exterior resin.

[Prior Art] FIG. 4 and FIG. 5 are external perspective views of a conventional polar chip type electronic component. Conventionally, in this type of chip-type electronic component, a plate-shaped anode terminal 13 is connected to an anode lead (not shown) led out from the element. On the other hand, after the cathode terminal 14 is connected and fixed to a cathode layer (not shown) formed on the surface of the element by a method such as soldering, it is covered with an exterior resin 15 having an insulating property,
It is manufactured by subjecting the anode terminal 13 and the cathode terminal 14 to processing such as cutting and bending.

Incidentally, FIG. 4 shows an example of a polar chip type electronic component according to Japanese Patent Application No. 61-303109.

[Problems to be solved by the device]

The above-described conventional polar chip-type electronic component is apt to cause erroneous mounting in which the polarity of the electronic circuit and the cathode of the electronic component are reversed when mounted on the electronic component such as a circuit board, and as a result, the electronic circuit of recent years It is becoming impossible to meet the needs for high added value and high reliability.

The purpose of the present invention is to prevent reverse mounting, and as a result, it is possible to eliminate the occurrence of performance deterioration of electronic components and the resulting malfunction of electronic circuits, and to improve the mounting efficiency on circuit boards. It is to provide a polar chip-type electronic component that can be used.

[Means for Solving the Problems]

The polar chip type electronic component of the present invention comprises an anode terminal drawn from the anode lead of the polar chip type electronic component element coated with the exterior resin to a pair of outer surfaces of the exterior resin facing each other.
The cathode terminal of the electronic component element has a cathode terminal drawn from the outer surface of the anode terminal of the exterior resin drawn out, the anode terminal and the cathode terminal are in parallel, and terminals of the same polarity are diagonal lines respectively. It is characterized by being placed on top.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an external perspective view showing the internal structure of an embodiment (solid tantalum capacitor) of a polar chip type electronic component of the present invention, and FIG. 2 is an external perspective view of the element in the state of FIG. 1 coated with an exterior resin. It is a figure. Element 1 of the solid electrolytic capacitor is
Using a molding technique such as a flat pressing molding method on the two side surfaces in the same direction of the tantalum powder compact, a sintered body obtained by implanting tantalum wires at positions eccentric to each other on both sides, and then sintering, It is processed sequentially such as dielectric formation, semiconductor layer formation, cathode conductor layer formation. At this time, since a dielectric, a semiconductor layer, and a cathode conductor layer are formed on one of the anode leads 2 similarly to the sintered body, they are dissolved in dilute hydrochloric acid so as not to interfere with the bonding in the subsequent process. In addition, if an insulating resin is applied to the planting portion of the anode lead, the leveling during melting becomes easy.

The anode lead 2 and the anode terminal 3 which are planted in this element 1 are joined by electric welding. The cathode terminal 4 is placed on the upper surface of the cathode layer 6 of the element 1 and has a cross section which is flush with the anode terminal 3. It has been processed into a shape. The cathode terminal 4 arranged so as to be parallel to the anode terminal 3 on the upper surface of the element 1 is fixed to the cathode layer 6 with a conductive adhesive or high-temperature solder.

Subsequently, the exterior resin 5 such as epoxy resin is exteriorly coated by a molding method. Exterior resin 5 for both anode and cathode
Is electrically connected inside, and is arranged in parallel with two outer surfaces of the exterior resin 5 in the same direction and is led out.

3 (a) and 3 (b) are external perspective views showing an embodiment of the present invention. FIG. 3 (a) shows an example in which the anode and cathode terminals 3 and 4 are cut to a predetermined size, bent at a substantially right angle along the side surface of the exterior resin 5, and then bent along the bottom surface.

FIG. 3 (b) shows an example in which the anode and cathode terminals 3 and 4 are bent substantially at right angles along the side surface of the exterior resin 5 and then bent in the direction opposite to the bottom surface.

[Effect of device]

As described above, according to the present invention, by arranging the anode terminal and the cathode terminal, which are led out from the device, in parallel at the opposite positions on the side surface of the exterior resin and the terminals of the same polarity, respectively, (1) When mounting on an electronic circuit such as a circuit board, the polarity of the anode and cathode terminals matches the polarity of the electronic circuit even if the electronic component is mistaken for right and left, and the performance of the electronic component may deteriorate due to reverse mounting. As a result, it is possible to eliminate the occurrence of malfunctions in electronic circuit operation.

(2) Compared with the conventional four-way terminal structure, the electrode terminals are aligned in one direction, so the mounting efficiency on the circuit board is improved and even if the exterior shape is square, the occurrence of defects due to reverse mounting is prevented. I can.

And so on.
