Abstract: A silver layer (24) is sandwiched between a tin layer (20) and a tin top coat (28) on an electrically-conductive substrate (14) which may comprise copper. The substrate having the three discrete metal layers thereon is heated to a temperature of at least about 220° C., preferably from about 220° C. to about 410° C., to melt the three layers. The melted layers are cooled to cause them to re-solidify as a tin-silver alloy layer (32) in which the silver is fully dispersed. A coated electrically conductive substrate (214) made as described above may be used as an electrical contact material.

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.
