Composite EMI shield
First Claim
1. An EMI shield having at least one compartment for enclosing circuitry of an electronic device, said shield comprising:
- a first member formed of an electrically-conductive first material; and
a second member formed of a an electrically-conductive second material different from the first material, the second material comprising an admixture of a polymeric component and an electrically-conductive particulate filler component, the second member being integrally joined to the first member, and having at least one wall which extends from the first member and which together with the first member defines at least a portion of said compartment.

Abstract
An EMI shield having at least one compartment for enclosing circuitry of an electronic device. The shield includes a first member formed of a first material such as a thin metal sheet or screen, or a metal-plated fabric or other electrically-conductive mesh, and a second member formed of a second material different than the first material which second material is an admixture of a plastic or other polymeric component and an electrically-conductive particulate filler component. The second member is integrally joined to the first member, and has at least one wall which extends from the first member and which together with the first member defines at least a portion of the compartment.
