Abstract

A thin, dielectric layer of insulation is provided with a plurality of spaced, rectangular openings. At each side of each opening the insulation is provided with a pair of spaced, integral tab portions which project part way into the opening. Rectangularly shaped ceramic capacitors, which are slightly smaller than the rectangular openings, are placed upon the tabs after which the insulation is partially cured to secure the capacitors to the tabs. The layer of insulation is then laminated between a pair of copper strips to produce a laminated bus bar in which the capacitors are secured in the openings with their marginal edges spaced from the surrounding edge of the associated opening, except where the sides of capacitors are engaged by the tabs. Before partially curing the layer of insulation opposite sides of each opening may be spread apart momentarily to allow the capacitors to be centered in the openings, after which the sides of the openings are released so that the tabs resiliently grip opposite side edges of the capacitors to hold them in the openings.
