Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a laminated solid 1FL capacitor in which valve metal foils such as aluminum foil and tantalum oil are laminated, and a method for manufacturing the same.

Conventional solid wL solution capacitors, for example, are made by connecting a lead wire terminal that will become an anode terminal to an A1 piece with a roughened surface, then chemically forming it to form a film, and then immersing it in a manganese nitrate bath solution and baking it. A manganese dioxide layer was formed. The confectionery with the manganese layer formed thereon is coated with a carbon black or carbon graphite suspension layer and dried to form a carbon layer. After that, a conductive paste is spread over the carbon layer, and the conductive paste is further coated with a carbon layer. Connect the SD card terminal. In this way, the confectionery with the anode and the M terminal connected to it is housed in a case and sealed or covered with an insulating resin to form a capacitor. In addition, instead of the Al plate of the element, a solid capacitor is also used, which is made of FH or a hand plate similar to the d-cut plate.

However, the capacitors made as described in U are completely different from each other if! If round rods or hook bodies are used for confectionery due to the difficulty in productivity due to the production of ii. There is a problem that it cannot be done. Furthermore, when foils or plates are used for confectionery, the workability of laminating them is poor, and since each sheet is handled one by one, V film or manganese dioxide N film is formed on the electrode foil.

The yield rate is poor because the carbon layer etc. easily break, and the breakage causes defects in the characteristics, resulting in a short lifespan.Dadvantage%1 Rarely 0 Under these circumstances, in recent years, products have become smaller, thinner, and cheaper. However, if these requirements cannot be met, such as the #J group, which loses the use of electrolytic capacitors to hybrid integrated circuits, it is necessary to attach electrolytic capacitors externally.
Alternatively, other methods were used, such as using inexpensive tantalum capacitors.

The present invention has been made in consideration of the above points, and is based on Al.

Electrodes are made by punching valve metal foil or wire mesh plate made of Ta, Nb, T1, etc. into thin pieces. 6, and relates to a multilayer solid electrolytic capacitor having a core layer thereof and a method for manufacturing the same, and will be explained below using actual examples. Figure 1 shows a side sectional view.
As shown in the plan view in Fig. 2, an A1 electrode foil (1) with a thickness of Q, In+ is etched by known means to roughen the surface, and then chemical conversion treatment is performed to form a fertilized film (2). ,
The electrode foil is punched into a comb shape as shown in FIG. 2 to obtain a comb-shaped electrode foil having a base (3) and a plurality of teeth (4). Or after the rough surface is punched out into a comb shape and treated with chemical conversion=y

Perform dankasei to rectify the previous 6-pi dankapiei (2). This process of immersion in the manganese bath solution, carbonization, and tanning is repeated several times to obtain the desired manganese dioxide layer (6). The comb-shaped manganese layer (6) formed in this way is laminated with a H-shaped sheet between the poles so that the insulating coatings (5) are pressed against each other, and each of the insulating coatings ( 5) by heating and adhering the AI'lii gokuhaku (1) as shown in Figure 3.
) are laminated with a gap in the amount of oil to form a laminated electrode. Alternatively, the type (2) electrode foil may be adhered by newly applying an adhesive onto the insulating coating film (5). This insulating coating (
The adhesion of 5) prevents the carbon P6iAgia liquid from coming to the terminal side due to capillary action during immersion in the carbon suspension in the post-process ◇Laminated Al electrode foil (

A carbon layer (7) as shown in the figure is formed.

As described above, it is laminated A (2) type Al'Nf

The end face of the A1 electrode foil (1), which will serve as one pole for this laminated electrode, is coated with a hardening material, dried, and then coated with carbon fiber (8). ) Drying by sending the Department of Electrical Engineering to the top.
It is explained and constitutes the terminal capital (9). This state is the fifth
As shown in the figure, cut along B-B'fi to the width of tooth (4) ~ 1
By doing so, it is possible to obtain a laminated capacitor (lO) having a fixed capacitance as shown in FIG.

In addition, in the 111th century example, carbon & (71) was formed by applying a layer of carbon to the carbon suspension, and then applying conductive paint to form the cathode terminal (8) and cathode terminal (9), and cutting. As described above, a 4M layered deactivated capacitor (flo) was obtained, but after forming the carbon layer (7), as shown in FIG. (7) After Peng repented the emperor (11) by injecting and molding an insulating material such as M fat from above, Ni] 5t114
) on the carbon layer (7) left on the tip of the base (3) to form the cathode terminal (19). It is also possible to form a laminated type LJ!II battery capacitor by cutting it after forming it.

In any case, if the resin exterior is removed except for all or a part of the wire electrode terminal 15 and the cathode terminal section, the capacitor is placed on the conductor of the printed circuit board. By setting and reflowing the solder, it becomes the old connection north on the board, and 1ql outside of the conventional electrolytic capacitor.
There is no need to use a single tantalum capacitor, and costs can be reduced.

In the above embodiment, the shape of the A1 electrode foil (1) is the second shape.
Although the case using the comb-shaped electrode foil shown in the figure has been described, it is also possible to use an A1 electrode foil (21) provided with grooves (24) on both sides as shown in FIG. Although the above embodiment describes the case where Al is used as the electrode foil, Ta-Nb5T
A valve metal such as 1 may be used, and the insulating coating film (5) is the contact layer of the sugar green M test (5) when the manganese nitrate M solution is poured into the base (3) and laminated. This is installed in order to prevent a short circuit caused by infiltration of carbon black or carbon graphite suspension into the base (3) side, that is, the terminal side.

- The material can be used effectively by making the polar oil shape as shown in Figure 8 and the dimensions of teeth (4) (24) and each tooth (4) + 241 the same size. In addition, since a large number of capacitors can be obtained easily and at the same time, it is possible to provide a cylindrical capacitor at a low cost, and since the carbon layer is formed in a laminated state by adhesion, there is no destruction of the carbon layer. Therefore, the leakage current h t
It is possible to obtain a multilayer solid-state capacitor with excellent ana characteristics.
