Abstract
Abstract An integrated circuit package of the surface-mountable type within which a battery is mounted is disclosed. Battery leads extend from the side of the package body opposite that which is adjacent the circuit board when mounted, and between which a conventional battery may be placed. Standoffs are located on the package body for supporting the battery above the package body, so that a gap is present therebetween. A housing is attached to the package over the battery, and has standoffs attached to its inner surface so that a gap is also present between the housing and the battery. The gaps may be air gaps or filled with a low thermal conductivity material. The gaps thermally insulate the battery from the package body and housing, so that the circuit may be subjected to solder reflow mounting to a circuit board, while insulating the high temperatures from the battery.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
109 words
A method of packaging a battery integrally with a packaged integrated circuit, comprising: packaging an integrated circuit chip within a package body, said package body having electrical connections of the surface-mountable type on one side, and having first and second battery connections disposed at an opposing side from said electrical connections; after said packaging step, connecting a battery to the first and second battery connections in such a manner that a gap is present between said package body and said battery; and attaching a housing to said package body in such a manner that said housing covers said battery, with a gap present between said battery and said housing.
Claim 2
Independent Claim
109 words
A method of packaging a battery integrally with a packaged integrated circuit, comprising: packaging an integrated circuit chip within a package body, said package body having electrical connections of the surface-mountable type on one side, and having first and second battery connections disposed at an opposing side from said electrical connections; after said packaging step, connecting a battery to the first and second battery connections in such a manner that a gap is present between said package body and said battery; and attaching a housing to said package body in such a manner that said housing covers said battery, with a gap present between said battery and said housing.
Claim 3
Dependent Claim
31 words
The method of claim 1, wherein said package body has a standoff attached to said opposing side; so that, after said connecting step, said battery is in contact with said standoff.
Claim 4
Dependent Claim
30 words
The method of claim 1, wherein said housing has a standoff mounted along an inner surface thereof so as to be in contact with said battery after said attaching step.
Claim 5
Dependent Claim
19 words
The method of claim 1, further comprising: after said attaching step, connecting the electrical connections to a circuit board.
Claim 6
Dependent Claim
22 words
The method of claim 4, wherein said step of connecting the electrical connections to a circuit board comprises a solder reflow process.
Claim 7
Dependent Claim
32 words
The method of claim 1, wherein said packaging step comprises: mounting an integrated circuit chip to a lead frame; and encapsulating said integrated circuit chip and lead frame with a plastic encapsulant.
Claim 8
Dependent Claim
24 words
The method of claim 6, wherein said encapsulating steps forms a standoff on the opposing side of said package body from the electrical connections.
Claim 9
Dependent Claim
30 words
The method of claim 1, wherein said packaging step comprises: mounting an integrated circuit chip to a header; and attaching a lid to said header over said integrated circuit chip.
Claim 10
Dependent Claim
22 words
The method of claim 8, further comprising: attaching a standoff to the opposing side of said package body from the electrical connections.
Claim 11
Dependent Claim
36 words
The method of claim 1, further comprising: attaching the battery to first and second battery leads; and wherein said connecting step comprises: connecting the first and second battery leads to the first and second battery connections.
Claim 12
Dependent Claim
16 words
The method of claim 10, wherein said placing step is performed prior to said connecting step.
Claim 13
Dependent Claim
22 words
The method of claim 1, further comprising: inserting a thermally resistive material into the gap between the battery and the package body.
