Identification and polarization of msi/lsi assembly and receptacle

Claim 2

A combination comprising: a. an electronic package having a plurality of downwardly depending pins on the under surface thereof, said pins being disposed about the periphery to provide at least two angular orientations for mating, said package having on the under surface thereof a generally centrally located first portion having no pins; b. a corresponding receptacle having pin receiving means disposed about the upper surface thereof in a configuration for receiving said pins, the upper surface thereof having a generally centrally located second portion; and c. one of said first and second portions having engraved thereon an alpha-numeric designation, the other of said first and second portions having embossed thereon a reverse image of said alpha-numeric designation for identifying said corresponding receptacle package and for mating engagement in proper axial alignment of said electronic package with said receptacle.

Claim 3

The combination according to claim 1 wherein said second portion has engraved thereon an obverse image of the alpha-numeric designation and said first portion has a reverse embossed image of said alpha-numeric designation.

Claim 4

The combination according to claim 1 wherein said second portion has an embossed obverse image of the alpha-numeric designation and said first portion has a reverse engraved image of said alpha-numeric designation.

Claim 5

The combination according to claim 1 wherein said second portion has an obverse image of the alpha-numeric designation and the electronic package has imprinted on the upper surface thereof the same alpha-numeric designation whereby the electronic package for mating receptacle is readily identifiable by observation.

Claim 6

In a circuit card assembly containing a plurality of physically identical but electronically different assemblies, the combination comprising: a. a plurality of physically identical receptacles affixed to said circuit card, each of said receptacles having pin receiving means positioned about the upper surface thereof, said pin receiving means being disposed about the periphery of said surface to provide at least two angular orientations for mating, each of said receptacles having a central portion on the upper surface thereof containing an obverse image of an alpha-numeric designation; and b. a plurality of physically identical but electronically different packages, each of said packages having depending pins on the under surface thereof adapted for mating engagement with said pin receiving means, each of said packages having on the undersurface thereof, a reverse image of an alpha-numeric designation, at least one of said obverse and reverse images being embossed and the other of said images being engraved with the same alpha-numeric designation for mating alignment in only one angular orientation, each said electronic packages having on the upper surface thereof an obverse image of the alpha-numeric designation corresponding to the receptacle adapted for receiving said package.

Claim 7

In a circuit card assembly containing a plurality of physically identical but electronically different assemblies, the combination comprising: a. a plurality of physically identical receptacles affixed to said circuit card, each of said receptacles having pin receiving means positioned about the upper surface thereof, said pin receiving means being disposed about the periphery of said surface to provide at least two angular orientations for mating, each of said receptacles having a central portion on the upper surface thereof containing an obverse image of an alpha-numeric designation; and b. a plurality of physically identical but electronically different packages, each of said packages having depending pins on the under surface thereof adapted for mating engagement with said pin receiving means, each of said packages having on the undersurface thereof, a reverse image of an alpha-numeric designation, at least one of said obverse and reverse images being embossed and the other of said images being engraved with the same alpha-numeric designation for mating alignment in only one angular orientation, each said electronic packages having on the upper surface thereof an obverse image of the alpha-numeric designation corresponding to the receptacle adapted for receiving said package.

Claim 8

A combination comprising: a. an electronic package having a plurality of downwardly depending pins on the under surface thereof, said pins being disposed about the periphery to provide at least two angular orientations foR mating, said package having on the under surface thereof a generally centrally located first portion having no pins; and b. a receptacle having pin receiving means disposed about the upper surface thereof in a configuration for receiving said pins, the upper surface thereof having a generally centrally located second portion, one of said first and second portions having engraved thereon an alpha-numeric designation, the other of said first and second portions having embossed thereon a reverse image of said alpha-numeric designation for mating engagement in proper axial alignment of said electronic package with said receptacle, said first portion having a separate sealing cap affixed to the undersurface of said electronic package and said second portion having a separate member inserted into and affixed within a recess in said receptacle with said separate member being recessed from the upper surface of said receptacle a distance at least equal to the thickness of said sealing cap.

Claim 9

A combination comprising: a. an electronic package having a plurality of downwardly depending pins on the under surface thereof, said pins being disposed about the periphery to provide at least two angular orientations foR mating, said package having on the under surface thereof a generally centrally located first portion having no pins; and b. a receptacle having pin receiving means disposed about the upper surface thereof in a configuration for receiving said pins, the upper surface thereof having a generally centrally located second portion, one of said first and second portions having engraved thereon an alpha-numeric designation, the other of said first and second portions having embossed thereon a reverse image of said alpha-numeric designation for mating engagement in proper axial alignment of said electronic package with said receptacle, said first portion having a separate sealing cap affixed to the undersurface of said electronic package and said second portion having a separate member inserted into and affixed within a recess in said receptacle with said separate member being recessed from the upper surface of said receptacle a distance at least equal to the thickness of said sealing cap.

Claim 10

The combination of claim 6 wherein said second portion has an insert having a knurled body portion with a disc flange on either side thereof, one of said disc flanges containing the alpha-numeric designation, said insert being molded in said receptacle.
