Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 91 words
An electronic package, comprising: a substrate; an electrical device coupled to said substrate; and, a lid that has a plate portion contiguous with said electrical device, an outer frame portion attached to said substrate and a bellows portion coupled to said outer frame portion and said plate portion, said lid being attached to said substrate so that said plate portion applies a pressure to said electrical device, said bellows portion extending between said plate portion and said outer frame portion in both an axial and longitudinal direction relative to said substrate.
Claim 2
Dependent Claim 91 words
An electronic package, comprising: a substrate; an electrical device coupled to said substrate; and, a lid that has a plate portion contiguous with said electrical device, an outer frame portion attached to said substrate and a bellows portion coupled to said outer frame portion and said plate portion, said lid being attached to said substrate so that said plate portion applies a pressure to said electrical device, said bellows portion extending between said plate portion and said outer frame portion in both an axial and longitudinal direction relative to said substrate.
Claim 3
Dependent Claim 19 words
The package as recited in claim 1, wherein said outer frame portion is attached to said substrate by solder.
Claim 4
Dependent Claim 20 words
The package as recited in claim 1, wherein said lid includes a plurality of fins extending form said plate portion.
Claim 5
Dependent Claim 14 words
The package as recited in claim 1, wherein said lid is constructed from aluminum.
Claim 6
Dependent Claim 19 words
The package as recited in claim 1, wherein said outer frame portion is attached to said substrate by epoxy.
Claim 7
Dependent Claim 19 words
The package as recited in claim 1, wherein said outer frame portion is attached to said substrate by gold.
Claim 8
Independent Claim 95 words
A method for assembling an electronic package, comprising the steps of; a) providing an electrical device that is mounted to a substrate; b) placing a lid adjacent to said electrical device so that a plate portion of said lid is contiguous with said electrical device and an outer frame portion of said lid is adjacent to said substrate, said plate portion being separated from said outer frame portion by a bellows portion which extends in both an axial and longitudinal direction relative to said substrate; and, c) coupling said outer frame portion to said substrate.
Claim 9
Independent Claim 95 words
A method for assembling an electronic package, comprising the steps of; a) providing an electrical device that is mounted to a substrate; b) placing a lid adjacent to said electrical device so that a plate portion of said lid is contiguous with said electrical device and an outer frame portion of said lid is adjacent to said substrate, said plate portion being separated from said outer frame portion by a bellows portion which extends in both an axial and longitudinal direction relative to said substrate; and, c) coupling said outer frame portion to said substrate.
Claim 10
Dependent Claim 22 words
The method as recited in claim 7, wherein said lid is attached to said substrate by heating said lid and said substrate.
