Abstract

Thin rectangular metal cups are press fitted into a row of rectangular holes in one and in another metal jigging strip. The patterns of holes in the two strips are identical. A small quantity of a conductive resin is dispensed into the cups of one strip and the cathode ends of a plurality of solid electrolyte capacitor bodies are pushed, preferably simultaneously, into the cups of this strip. A bonding resin is dispensed into the cups of the other strip and the anode ends of the capacitor bodies are pushed into the cups of this other strip. Near perfect registration and alignment of the two terminal cups of each capacitor body is achieved and the cost of terminating may be reduced in this disciplined and automatable method. These advantages are of greatest significance in terminating very small capacitors.

Dependent claims

A method for terminating solid electrolyte capacitors including providing a plurality of solid electrolyte capacitor bodies each of said bodies having an anode wire extending from an anode end thereof, and applying an insulating coating over said anode end and the adjacent sides of said each body so that the cathode counterelectrode is exposed at the opposite and namely the cathode end of said each body, wherein the improvement comprises:

a. forming a plurality of rectangular cups of a thin metal, each of said cups having four sides and a bottom;
b. pressing a first group of said metal cups into interference fitting rectangular holes, respectively, provided therefor in a first jigging strip, said holes being in a row and spaced therein at predetermined intervals and at predetermined orientations;
c. pushing each of said cathode ends into one of said first group cups, respectively, after applying a conductive resin beween each of said cathode ends and the corresponding of said cups;
d. curing said conductive resin;
e. pressing a second group of said cups into interference fitting rectangular holes, respectively, provided therefor in a second jigging strip, said holes in said second strip being in a row and spaced therein at said predetermined intervals and predetermined orientations;
f. pushing each of said anode ends into one of said second group cups, respectively, after applying a bonding resin between each of said anode ends and the corresponding of said second group cups;
g. curing said bonding resin;
h. making an electrical connection between each of said anode wires and the corresponding of said second group cups;
and
i. removing said jigging strips from said capacitor bodies.
