A module includes: a substrate having a first surface; a first component mounted on the first surface; a first protruding electrode disposed on the first surface; a first resin film covering the first component along a shape of the first component, covering at least a part of the first surface, and partially covering the first protruding electrode; and a first shield film formed to overlap with the first resin film. The first protruding electrode includes a first sharpened portion, the first protruding electrode is exposed from the first resin film in at least a part of the first sharpened portion, and the first shield film is electrically connected to the first protruding electrode by covering a portion where the first protruding electrode is exposed from the first resin film.

Provided is an electromagnetic wave shielding film capable of easily exhibiting excellent conductivity between a ground member and a shielding layer when the ground member is disposed on the electromagnetic wave shielding film. In the electromagnetic wave shielding film 1, the conductive adhesive layer 11, the shielding layer 12, and the insulating layer 13 are laminated in this order, and a ratio [conductive adhesive layer/insulating layer] of Martens hardness of the conductive adhesive layer 11 in accordance with ISO14577-1 to Martens hardness of the insulating layer 13 in accordance with ISO14577-1 is 0.3 or more.

An electrically conductive material configured having at least one opening of various unlimited geometries extending through its thickness is provided. The opening is designed to modify eddy currents that form within the surface of the material from interaction with magnetic fields that allow for wireless energy transfer therethrough. The opening may be configured as a cut-out, a slit or combination thereof that extends through the thickness of the electrically conductive material. The electrically conductive material is configured with the cut-out and/or slit pattern positioned adjacent to an antenna configured to receive or transmit electrical energy wirelessly through near-field magnetic coupling (NEMC). A magnetic field shielding material, such as a ferrite, may also be positioned adjacent to the antenna. Such magnetic shielding materials may be used to strategically block eddy currents from electrical components and circuitry located within a device.

The present application relates to an electromagnetic wave shielding film, which can provide an electromagnetic wave shielding film having excellent mechanical strength, flexibility, electrical insulation properties, bonding properties with other constituents, oxidation and high-temperature stability and the like, while having excellent electromagnetic shielding ability.

A lightweight transportable containerized shelter includes wall panels made of a non-metal composite material coated at least on its inner face with a metal layer for EMI protection. The several wall panels are secured to a metal structural frame without the use of fasteners so as to define a containerized transportable shelter. The shelter meets ISO standards 668 and 1496. The shelter provides a continuous barrier to electromagnetic signals. Moreover, the containerized shelter is amenable to nine high stacking as required for ISO certification.

A module comprises: a substrate having a first surface; a first component and a second component mounted on the first surface; a conductive member mounted therebetween; and a resin seal disposed to cover the first surface, the first component and the second component and also seal a portion of the conductive member. The resin seal has a recess that exposes at least a portion of the conductive member, and inside the recess the resin seal and the conductive member have a side surface and a surface, respectively, covered with a first shield film. The first shield film inside the recess is covered with a second shield film smaller in thickness than the first shield film. The resin seal has a surface facing away from the first surface and covered with the second shield film.

A shielded cable includes a first insulated wire including a first central conductor, and a first insulating layer provided around the first central conductor, a second insulated wire including a second central conductor, and a second insulating layer provided around the second central conductor, the second insulated wire being disposed parallel to the first insulated wire, a third insulating layer provided around the first insulated wire and the second insulated wire, a shielding layer provided around the third insulating layer, a drain wire in contact with the shielding layer, and a fourth insulating layer provided around the shielding layer and the drain wire.

A high permeability metal (mu-metal) shield is placed in close proximity of a main logic board (MLB) of a wearable device, such as an earbud, to reduce eNoise. Radio frequency current flow induced by an antenna radiator will flow over the MLB and its associated ground plane, including the mu-metal shield. To reduce an impact of the mu-metal shield on antenna performance, a coating process is done on the mu-metal shield, by developing a thin layer of high conductivity, low permeability copper or silver on top of the mu-metal.
