Abstract
A method of making a capacitor from a canister having first and second mutually insulated electrically conductive interior surfaces, an open end, and an insulative end surface opposite the open end, and from a capacitive structure having a plurality of pairs of spaced apart electrically conductive plates, a first electrically conductive bus connecting one plate of each pair together to the exclusion of the other plate of each pair, and a second electrically conductive bus connecting the other plate of each pair together to the exclusion of the one plate. The first step of the method is to place the capacitive structure in the canister so the first bus lies adjacent to the first surface of the canister to define therewith and the closed end surface of the canister a first cavity in communication with the open end of the canister and so the second bus lies adjacent to the second surface of the canister to define therewith and the closed end surface of the canister a second cavity in communication with the open end of the canister. The first and second cavities are out of direct communication with each other. The second step is to introduce into the open end of the canister an electrically conductive solidifiable fluidic connecting material. The connecting material is a thermoset loaded with electrically conductive particles having higher density than the thermoset. The third set is to rotate the canister about a center of rotation toward which its open end faces to induce by centrifugal force flow of the fluidic connecting material into the first and second cavities. The final step is to cure the connecting material. The centrifugal force resulting from rotation of the canister overcomes the surface tension of the connecting material so the connecting material fills the cavities without voids, thereby forming electrical connections of high integrity between the respective conductive surfaces of the canister and the buses of the capacitive structure.
