Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
102 words
An integrated circuit package with a removable shield comprising: an encapsulated integrated circuit having a plurality of leads; a carrier which supports the encapsulated integrated circuit; a removable shield fabricated from a conductive material mounted on the carrier so as not to make contact with the encapsulated integrated circuit, the removable shield being of such a size and shape as to be held in place on the carrier by spring action; and an opening through the removable shield to allow a predetermined access to the encapsulated integrated circuit, wherein the opening has a size to minimize exposure of the plurality of leads.
Claim 2
Dependent Claim
102 words
An integrated circuit package with a removable shield comprising: an encapsulated integrated circuit having a plurality of leads; a carrier which supports the encapsulated integrated circuit; a removable shield fabricated from a conductive material mounted on the carrier so as not to make contact with the encapsulated integrated circuit, the removable shield being of such a size and shape as to be held in place on the carrier by spring action; and an opening through the removable shield to allow a predetermined access to the encapsulated integrated circuit, wherein the opening has a size to minimize exposure of the plurality of leads.
Claim 3
Dependent Claim
76 words
An integrated circuit package with removable shield, comprising: an encapsulated integrated circuit having a plurality of leads; a carrier which supports the encapsulated integrated circuit; and a removable shield fabricated from a conductive material mounted on the carrier, the removable shield being of such a size and shape as to be held in place on the carrier by spring action, wherein the encapsulated integrated circuit and associated carrier are suited for use in tape automated bonding.
Claim 4
Dependent Claim
76 words
An integrated circuit package with removable shield, comprising: an encapsulated integrated circuit having a plurality of leads; a carrier which supports the encapsulated integrated circuit; and a removable shield fabricated from a conductive material mounted on the carrier, the removable shield being of such a size and shape as to be held in place on the carrier by spring action, wherein the encapsulated integrated circuit and associated carrier are suited for use in tape automated bonding.
Claim 5
Independent Claim
86 words
A method for protecting a packaged integrated circuit with a removable shield, comprising: packaging an integrated circuit with a package having a plurality of leads; mounting the package on a carrier; fitting a removable shield fabricated from a spring material onto the carrier in such a way as to protect the plurality of leads from mechanical damage; and opening a hole in the shield to allow a predetermined access to the package, wherein the opening has a size to minimize exposure of the plurality of leads.
Claim 6
Independent Claim
86 words
A method for protecting a packaged integrated circuit with a removable shield, comprising: packaging an integrated circuit with a package having a plurality of leads; mounting the package on a carrier; fitting a removable shield fabricated from a spring material onto the carrier in such a way as to protect the plurality of leads from mechanical damage; and opening a hole in the shield to allow a predetermined access to the package, wherein the opening has a size to minimize exposure of the plurality of leads.
Claim 7
Dependent Claim
91 words
An integrated circuit package with a removable shield, comprising: an encapsulated integrated circuit die having a plurality of leads; a TAB carrier which supports the encapsulated integrated circuit die; a removable shield fabricated from a metallic spring material of a predetermined thickness which clips onto the TAB carrier, the removable shield being of such a size and shape as to be held in place on the TAB carrier solely by spring action of the removable shield; and an opening through the shield to allow a predetermined access to the TAB package.
Claim 8
Dependent Claim
91 words
An integrated circuit package with a removable shield, comprising: an encapsulated integrated circuit die having a plurality of leads; a TAB carrier which supports the encapsulated integrated circuit die; a removable shield fabricated from a metallic spring material of a predetermined thickness which clips onto the TAB carrier, the removable shield being of such a size and shape as to be held in place on the TAB carrier solely by spring action of the removable shield; and an opening through the shield to allow a predetermined access to the TAB package.
Claim 9
Dependent Claim
43 words
The integrated circuit package with removable shield of claim 4 further comprising: a plurality of fingers on the removable shield which serve to grip the TAB carrier by spring action, serving to securely hold the removable shield in place on the TAB carrier.
