Abstract
Abstract A method is described for manufacturing a backplane in which plugs are inserted into apertures in the backplane to mask the surfaces of the apertures. A nonconductive coating is formed on the backplane while the plugs are positioned in such apertures. Thereafter, electrical contacts are inserted into the apertures to remove the plugs therefrom.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
78 words
In the method of manufacturing a backplane, the steps comprising: forming a plurality of apertures in the backplane; inserting plugs in selected apertures in said backplane to mask the surfaces of said apertures; forming a nonconductive coating on said backplane while said plugs are positioned in said selected apertures; thereafter removing at least some of said plugs from their respective apertures; and mounting conductive elements in at least some of said aper-tures from which said plugs are removed.
Claim 2
Dependent Claim
78 words
In the method of manufacturing a backplane, the steps comprising: forming a plurality of apertures in the backplane; inserting plugs in selected apertures in said backplane to mask the surfaces of said apertures; forming a nonconductive coating on said backplane while said plugs are positioned in said selected apertures; thereafter removing at least some of said plugs from their respective apertures; and mounting conductive elements in at least some of said aper-tures from which said plugs are removed.
Claim 3
Dependent Claim
24 words
A method as set forth in claim 1 wherein: said backplane is formed of aluminum; and said coating is formed by anodizing said backplane.
Claim 4
Dependent Claim
38 words
A method as set forth in claim 1 wherein: said plugs are connected to a common carrier strip prior to insertion into said selected apertures; and said plugs are torn from said strip upon insertion into said apertures.
Claim 5
Dependent Claim
24 words
A method as set forth in claim 1 wherein: said plugs are removed from said apertures by mounting said conductive elements in said apertures.
Claim 6
Dependent Claim
54 words
In the method of manufacturing a backplane, the steps comprising: forming an aperture in an aluminum backplane; inserting a plug in said aperture to mask the surfaces of the aperture; anodizing said backplane while said plug is positioned in said aperture; and inserting a conductive element into said aperture to remove said plug therefrom.
Claim 7
Dependent Claim
54 words
In the method of manufacturing a backplane, the steps comprising: forming an aperture in an aluminum backplane; inserting a plug in said aperture to mask the surfaces of the aperture; anodizing said backplane while said plug is positioned in said aperture; and inserting a conductive element into said aperture to remove said plug therefrom.
