Matrix board

Claim 1

In a combination with an electronic assembly for connecting a bypass capacitor to a different electronic component with dependent leads, said component being mounted on a matrix board formed of an electrically insulating material provided with a plurality of apertures arranged in a rectangular grid with centers spaced apart by distances selected from the values which are integral multiples of about 0.1 inch, said matrix board further being provided on a first surface thereof with an electrically conductive ground plane path disposed so as to clear each of the majority of said apertures over a circular area, centered on each aperture, not exceeding about 0.1 inch in diameter; the improvement including: first electrically conductive pin means for electrically connecting leads of said electronic component to a selected plurality of adjacent ones of said apertures so that said component is mounted adjacent the opposite surface of said board, said first conductive pin means extending through said selected plurality of apertures and beyond said first surface; second electrically conductive pin means for electrically connecting leads of said capacitor to a selected pair of said apertures adjacent said selected plurality of apertures so that said capacitor is disposed adjacent said opposite surface with said second conductive pin means extending through said selected pair of apertures and beyond said first surface; a discrete connector comprising: (A) an elongated electrically insulating wafer having a length greater than about 0.1 inch and no longer than about 0.2 inch and having a width less than about 0.1 inch, said wafer having a pair of small circular holes penetrating therethrough and spaced about 0.1 inch center to center, and (B) an electrically conductive bus disposed on one surface of said wafer and extending at least between said pair of circular holes; said connector being assembled adjacent said first surface so that said insulating wafer is positioned between said first surface and said electrically conductive bus, and so aligned that a selected pin of said first conductive pin means and a selected pin of said second conductive pin means respectively penetrate through said pair of circular holes so as to make electrical contact with said electrically conductive bus; and a discrete pair of electrically conductive, centrally apertured discs, each having an nominal outside diameter no greater than about 0.1 inch but greater than that of said circular area; said discs being assembled in electrical contact with said ground plane and aligned respectively in contact with a selected pin of said first conductive pin means and another pin of said second conductive pin means.
