Description

[Detailed Description of the Invention] The present invention is '! This article relates to a method for manufacturing a solid electrolytic capacitor using an organic semiconductor made of a complex salt of ONQ as a solid electrolyte.

An organic semiconductor consisting of a complex salt of 7,7.8.8-tetraleanoquinodimethane, called ONQ, is melted and then impregnated into a solid electrolyte by cooling and cooling.
! 7r Law Ha ##■ Moka No. 56-58816 and special application 1987-
This has already been proposed as an invention in No. 116841.

The present invention is characterized by rapidly cooling the organic semiconductor after impregnating the organic semiconductor in the method C: using a cooling medium. Effects can be obtained. The reason why such an effect appears is not clear, but it is thought to be as follows. That is, when a substance in a molten state is cooled and crystallized, the crystals formed by gradual cooling become coarse, whereas the crystals formed by rapid cooling become coarse.
If it is removed, it will become moldy and therefore,
This is because the molten organic semiconductor adheres finely and firmly to the condensate element by rapid cooling.

In the present invention, the effect becomes more pronounced as the temperature difference between the condensation element and the cooling medium immediately before cooling increases, and should preferably be 200° C. or more.

The cooling medium used in the present invention is a relatively small one that reacts with the complex salt of TOMQ, and may be water or an aqueous solution such as methanol, ethanol, acetone, or acetonide 5#.
Very low-temperature gases obtained from medium, dry ice, liquid nitrogen, etc. are most suitable.

This threat will be explained below using examples.

First, a winding bulkhead for an electrolytic condenser (rated at 4.7 Voice ν, for 50 ma)! Prepare and preheat it to about 260° C. Note that the separator of such an element has been carbonized J6 in advance.

- 10,000, a case in which powder of n-propyl, isochrom, and TOIQ, which is a complex salt of TOIQ, is used as an organic semiconductor under moderate pressure, and an aluminum case with good thermal conductivity. 0°C to 500°C: Heat to melt and liquefy, then insert the preheated element prepared as above into the case and cool. This causes the organic semiconductor to solidify in a state impregnated with the seven paretas 62, which acts as an electrolyte of the monolithic electrolytic condenser.

Finally, the case is sealed with resin to complete the solid electrolytic capacitor. It should be noted that each of the aluminum foils of the element has an anode tart and a cathode lead r covered with snow, and these leads penetrate the sealing resin and extend to the outside, as in a normal capacitor.

The capacitors provided as the result of the characteristic test are those obtained by cooling the above organic semiconductor at room temperature and C:5.
The above cases were prepared by completely immersing the sample in pure water at 4°C without submerging it. The latter case is in accordance with the present invention-2, and the former case is a reference example for comparison. In either case, cooling is started until the molten organic semiconductor is thermally decomposed. More specific ζ:
is preferably within 10 seconds after completion of liquefaction.

The characteristics test results of each capacitor in the above example and S example are as follows.

Condensing element 4: Capacitor characteristics can be improved in capacitor fabrication method C2 in which a solid electrolyte is formed by cooling after impregnation.
