Abstract:
An EMI shielding enclosure, for an electronic assembly, comprising a ground plane of a printed circuit connected to a shaped EMI shielding cover. The cover results from thermoforming a composite sheet of several layers, including a carrier for a fibrous metal mat that has fibers substantially surrounded by a fiber-coat. Connection of the cover to the ground plane, to form the EMI shielding enclosure, requires the fiber-coat to adhere to the printed circuit in the vicinity of the ground plane.
Abstract:
An electromagnetic shield is incorporated into a radiotelephone. The radiotelephone includes a printed circuit board having a ground trace extending around an electrical circuit formed on the printed circuit board. The electromagnetic shield is disposed adjacent the printed circuit board for isolating the electrical circuit thereon. Forming a part of the electromagnetic shield is a face, a side wall, and a series of spaced apart spring contacts that extend from the side wall for electrical contact with the ground trace on the printed circuit board. Disposed over the shield is a housing structure that engages the shield and urges the shield against the printed circuit board such that the spring contacts thereof engage and make electrical contact with the ground trace of the printed circuit board.

Abstract:
The present invention relates to a shield case and an antenna set comprising the same, wherein the shield case includes a shield surface for shielding embedded electronic elements against electromagnetic wave, a fixing unit coupled with a substrate mounted with the electronic elements, signal receivers for receiving a signal of desired frequency, and two strip antennas connected to a border of the shield surface, each antenna facing the other across the shield surface.
Abstract:
According to various aspects, exemplary embodiments are provided of shielding apparatus suitable for use in providing electromagnetic interference shielding for one or more electrical components on a substrate. In one exemplary embodiment, a shielding apparatus generally includes first and second walls. The first wall includes laterally spaced-apart detent protrusions. The second wall includes an edge portion disposed relative to the first wall such that an interface between the edge portion of the second wall and the first wall is substantially sealed against the ingress and/or egress of electromagnetic interference through the interface. The edge portion of the second wall is engaged generally between and laterally confined by the laterally spaced-apart detent protrusions of the first wall, such that the laterally spaced-apart detent protrusions inhibit movement of the second wall relative to the first wall. Accordingly, this helps retain the interface between the edge portion of the second wall and the first wall substantially sealed against the ingress and/or egress of electromagnetic interference through the interface.
Abstract:
The present invention is directed to a reinforced substrate apparatus (100) and method (600) for reinforcing a substrate (110). The substrate apparatus includes the substrate, a first shield (115, 215) coupled to the substrate and at least a second shield (120, 220) coupled to the substrate. A strengthening member (125, 225, 275) can be coupled to the first shield and the second shield without necessarily contacting the substrate. The method can include the step of attaching (620) the first shield and the second shield to the substrate where at least one among the first shield and the second shield shields circuitry on the substrate. The method also includes the step of coupling (640) a strengthening member to the first shield and the second shield.
Abstract:
The RF shield (2) having a plurality of interconnected sidewalls (6, 8, 10, 12), substantially open bottom region, and a hingeably connected top cover portion (4), having a top cover latch (14) and disposed along the top edge of one of the sidewalls. The top cover portion (4) of the shield (2) is adapted to hinge toward another one of the sidewalls (6, 8, 10, 12) such that the top cover latch (14) engages a hole (20) disposed on the other sidewall being engaged and completing a protective enclosure about electrical components and preventing those components from causing electromagnetic interferences. The RF shield (2) of the present invention allows for easy opening of the top cover portion (4) to provide access to the enclosure for rework or repair of the electrical components covered by the shield, without having to unsolder the unit from a substrate containing the electrical components.
