Abstract
A method of forming an electrical backplane comprising providing an initially oversized ground and potential plate, forming discontinuous slots in a staggered relationship near the edges of the top surface of one of the plates and the bottom surface of the other plates, laminating the plates together by filling the slots with insulative material and trimming the edge portions off by cutting through the filled slots and webs connecting the slots whereby exposed backplane edges lie opposite insulation in the slots of the plates.

A method of producing a multilayer backplane assembly of the type including a conductive metal potential plate, a conductive metal ground plate, and insulative plates between and outside of the potential and ground plates, said method comprising the steps of forming oversize potential and ground plates, forming slots along the edge portions of each of the potential and ground plates which slots separate a main body of each potential and ground plate from oversize marginal edge portions, said slots being formed in segments interrupted by webs which connect the marginal edge portions to the main body portion of each of said potential and ground plates, laminating said potential, ground and insulative plates together and filling said slots with insulative material, and trimming off said marginal edge portions by cutting through said filled slots and severing said webs.
A method of producing a multilayer backplane assembly of the type including a conductive metal potential plate, a conductive metal ground plate, and insulative plates between and outside of the potential and ground plates, said method comprising the steps of forming oversize potential and ground plates, forming slots along the edge portions of each of the potential and ground plates which slots separate a main body of each potential and ground plate from the oversize marginal edge portions, said slots being formed in segments interrupted by webs which connect the marginal edge portions to the main body portion of each of said potential and ground plates, each side of said potential and ground plates being formed with a plurality of said slots, each slot being separated from an adjacent slot by one of said webs, and the slots formed in said ground plate being staggered relative to the slots formed in said potential plate whereby in the laminated assembly each slot in one of said potential and ground plates is opposite a web in the other plate, laminating said potential, ground and insulative plates together and filling said slots with insulative material, and trimming off said marginal edge portions by cutting through said filled slots and severing said webs.
