Abstract
Abstract A rectangular monolithic ceramic capacitor chip has two or more electrodes extending to separate portions, respectively, of one particular edge of the chip. Parallel spaced conductive layer strips are formed on only one major face of the chip. The strips extend, respectively, over the separte portions of the particular edge to contact the electrodes. A multiple chip termination method includes aligning the chips in a column with the particular edges perpendicular to the column. A stamp has at least two parallel resilient bars each having stubby finger-like projections. Conductive ink is applied to the stamp bars, which are placed over the column with the projections entering the spaces, respectively, between the adjacent chips. Sliding the bar back and forth deposits ink on the one major face and squeezes a small amount of ink on the particular edge portions to contact the extended electrodes. Further, a matrix of ceramic capacitor chips having many columns can be ink coated in one step using one stamp.
