Abstract
Abstract An RF conductive shield can be fabricated from, and adhered to, a nonconductive substrate in the following manner. The RF conductive shield is fabricated in a predetermined geometric shape on the nonconductive substrate. Once the RF conductive shield is fabricated, it is cut from the nonconductive substrate to produce a separate RF shield. Having a separate RF shield, it can be placed on the nonconductive substrate in a predetermined location and adhered thereto.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
74 words
An RF shield apparatus comprising: at least one nonconductive substrate having a predetermined conductive layout for electronic component coupling; at least one predetermined geometric conductive shield fabricated from the at least one substrate; and nonconductive material adhered to at least one major surface of the at least one predetermined geometric conductive shield; such that the predetermined layout and the at least one predetermined geometric conductive shield are fabricated substantially simultaneously on the nonconductive substrate.
Claim 2
Dependent Claim
74 words
An RF shield apparatus comprising: at least one nonconductive substrate having a predetermined conductive layout for electronic component coupling; at least one predetermined geometric conductive shield fabricated from the at least one substrate; and nonconductive material adhered to at least one major surface of the at least one predetermined geometric conductive shield; such that the predetermined layout and the at least one predetermined geometric conductive shield are fabricated substantially simultaneously on the nonconductive substrate.
Claim 3
Dependent Claim
35 words
In the RF shield apparatus of claim 1, the predetermined geometric conductive shield further comprises placement tabs such that the RF shield apparatus, when mounted to a substrate, is mounted substantially perpendicular to the substrate.
Claim 4
Dependent Claim
39 words
The RF shield apparatus of claim 1 further comprises a nonconductive area such that, when the RF shield is mounted to the substrate, a portion of the predetermined conductive layout substantially physically contacts the RF shield without electrical coupling.
Claim 5
Independent Claim
100 words
A method for fabricating and adhering at least one RF conductive shield to a nonconductive substrate, the method comprises the steps of: a) fabricating, in a predetermined geometric shape, the at least one RF conductive shield on the nonconductive substrate; b) cutting the at least one RF conductive shield from the nonconductive substrate to produce at least one separate RF shield; c) placing each of the at least one separate RF shield on the nonconductive substrate in a predetermined location; and d) adhering each of the at least one separate RF shield to the nonconductive substrate in the predetermined location.
Claim 6
Independent Claim
100 words
A method for fabricating and adhering at least one RF conductive shield to a nonconductive substrate, the method comprises the steps of: a) fabricating, in a predetermined geometric shape, the at least one RF conductive shield on the nonconductive substrate; b) cutting the at least one RF conductive shield from the nonconductive substrate to produce at least one separate RF shield; c) placing each of the at least one separate RF shield on the nonconductive substrate in a predetermined location; and d) adhering each of the at least one separate RF shield to the nonconductive substrate in the predetermined location.
Claim 7
Dependent Claim
25 words
In the method of claim 4, the fabrication of step (a) further comprises plating the at least one RF conductive shield with a conductive material.
Claim 8
Dependent Claim
36 words
The method of claim 5 further comprises applying, over a substantial portion of a major surface of the at least one RF conductive shield, a nonconductive layer that insulates the at least one RF conductive shield.
Claim 9
Dependent Claim
27 words
In the method of claim 5, the fabrication of step (a) further comprises plating edges of the at least one RF conductive shield with a conductive material.
Claim 10
Dependent Claim
26 words
In the method of claim 4, the placement of step (c) further comprises placing the at least one RF conductive shield with a vacuum placement device.
