Abstract
Abstract A method of forming a module includes positioning a circuit card, such as a memory card, between separate frameworks and welding the frameworks together to encase the circuit card. The frameworks are preferably welded using sonic wave energy, thereby further enhancing the structural strength of the assembly. The assembly also includes cover and base panels. The panels are bent to further enhance the structural strength. In the preferred embodiment, the frameworks are injection molded onto the panels.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
185 words
A method of forming a module to be selectively connected to an electronic device comprising: forming a cover panel and a base panel; molding a first frame portion onto said cover panel, including forming molded material along opposed lateral edges of said cover panel; molding a second frame portion onto said base panel, including forming molded material along opposed lateral edges of said base panel; positioning a printed circuit card between said first and second frame portions such that a connector extends at first ends of said first and second frame portions; and welding said first frame portion to said second frame portion; said steps of forming said cover panel and molding said first frame portion including bending said base panel along said lateral edges thereof, thereby forming a bend of said base panel extending along the entire thickness of said first frame portion; said steps of forming said base panel and molding said second frame portion including bending said base panel along said lateral edges thereof, thereby forming a bend of said base panel extending along the entire thickness of said second frame portion.
Claim 2
Independent Claim
185 words
A method of forming a module to be selectively connected to an electronic device comprising: forming a cover panel and a base panel; molding a first frame portion onto said cover panel, including forming molded material along opposed lateral edges of said cover panel; molding a second frame portion onto said base panel, including forming molded material along opposed lateral edges of said base panel; positioning a printed circuit card between said first and second frame portions such that a connector extends at first ends of said first and second frame portions; and welding said first frame portion to said second frame portion; said steps of forming said cover panel and molding said first frame portion including bending said base panel along said lateral edges thereof, thereby forming a bend of said base panel extending along the entire thickness of said first frame portion; said steps of forming said base panel and molding said second frame portion including bending said base panel along said lateral edges thereof, thereby forming a bend of said base panel extending along the entire thickness of said second frame portion.
Claim 3
Dependent Claim
29 words
The method of claim 1 wherein molding said first frame portion includes forming first and second spaced apart members extending along said opposed lateral edges of said cover panel.
Claim 4
Dependent Claim
29 words
The method of claim 2 wherein molding said second frame portion includes forming third and fourth spaced apart members extending along said opposed lateral edges of said base panel.
Claim 5
Dependent Claim
20 words
The method of claim 1 wherein providing said cover and base panels is a step of providing planar metallic members.
Claim 6
Dependent Claim
25 words
The method of claim 1 wherein molding said first and second frame portions are steps of injection molding plastic onto metallic cover and base panels.
Claim 7
Dependent Claim
31 words
The method of claim 1 further comprising fixing said connector to said printed circuit card such that said connector is attachable to a Personal Computer Memory Card International Association (PCMCIA) port.
Claim 8
Dependent Claim
24 words
The method of claim 6 further comprising fixing an input/output connection means on an end of said printed circuit card opposite to said connector.
Claim 9
Dependent Claim
19 words
The method of claim 1 wherein positioning said printed circuit card is a step of positioning a memory card.
Claim 10
Dependent Claim
29 words
The method of claim 1 wherein welding said first frame portion to said second frame portion includes supplying sonic wave energy to vibrate said first and second frame portions.
Claim 11
Independent Claim
165 words
A method of forming a module to be selectively connected to an electronic device comprising: forming a first encasement section having a first metallic panel and a multiple-piece first plastic frame portion molded thereon, bending said first metallic panel along lateral edges thereof, thereby forming a bend extending along an entire thickness of said first plastic frame portion; forming a second encasement section having a second metallic panel and a multiple-piece second plastic frame portion molded thereon, bending said second metallic panel along lateral edges thereof, thereby forming a bend extending along an entire thickness of said second plastic frame portion; joining a PCMCIA-compatible connector to a circuit board; joining a second connector to said circuit board on a side opposite to said PCMCIA-compatible connector; trapping said circuit board between said first and second plastic frame portions such that said connectors are accessible through openings between said first and second frame portions; and welding said first and second plastic frame portions using sonic wave energy.
Claim 12
Independent Claim
165 words
A method of forming a module to be selectively connected to an electronic device comprising: forming a first encasement section having a first metallic panel and a multiple-piece first plastic frame portion molded thereon, bending said first metallic panel along lateral edges thereof, thereby forming a bend extending along an entire thickness of said first plastic frame portion; forming a second encasement section having a second metallic panel and a multiple-piece second plastic frame portion molded thereon, bending said second metallic panel along lateral edges thereof, thereby forming a bend extending along an entire thickness of said second plastic frame portion; joining a PCMCIA-compatible connector to a circuit board; joining a second connector to said circuit board on a side opposite to said PCMCIA-compatible connector; trapping said circuit board between said first and second plastic frame portions such that said connectors are accessible through openings between said first and second frame portions; and welding said first and second plastic frame portions using sonic wave energy.
Claim 13
Dependent Claim
24 words
The method of claim 10 wherein forming said first and second encasement sections each including injection molding said frame portions to said metallic panels.
