    摘要: An electromagnetic wave shielding film has permeability to volatile components, shielding characteristics, and resistance to folding. The electromagnetic wave shielding film includes an adhesive layer; a metal layer made of a metal and placed on the adhesive layer; and an insulating layer placed on the metal layer. Multiple openings are formed in the metal layer; the openings include openings (A) including island-shaped metal layer fragments, each opening (A) having island-shaped metal layer fragments formed therein, and the openings (A) including island-shaped metal layer fragments include openings (A1) including one or more island-shaped metal layer fragments. Each opening (A1) defines an opening (A) including island-shaped metal layer fragments in which a total area of the island-shaped metal layer fragments accounts for 40 to 80% of an area inside a contour of the opening (A).

    摘要: This document describes apparatuses and techniques for providing a flexible connector between a secondary circuit board and a main logic board with a permeability shield to increase impedance of the flexible connector to reduce antenna loss from an antenna via the flexible connector to the main logic board. For example, an apparatus includes a secondary circuit board supporting one or more control pads and an antenna. A flexible connector includes a plurality of conductive traces configured to electrically couple the one or more control pads of the secondary circuit board to a coupling on a main logic board. A permeability shield is configured to be disposed along one or more portions of the flexible connector. The permeability shield is configured to increase impedance of the flexible connector to reduce antenna loss of the antenna via the control pads and the flexible connector to the main logic board.

    摘要: The disclosure relates to a filter circuit on an electric motor which has electrical connections at a connection end for connection to a supply voltage (U). The filter circuit consists of at least one capacitor bridge arranged between the connections of the electric motor for radio interference suppression. For increased electromagnetic compatibility (EMC), the filter circuit is arranged on a circuit board and held on the connection end of the electric motor. The circuit board has a capacitor bridge with interference suppression capacitors, which is connected between the electrical connections of the electric motor, wherein an interference suppression capacitor has a longitudinal axis between its electrical connections in the longitudinal direction. The interference suppression capacitors are arranged on the circuit board with their longitudinal axes aligned in different spatial directions.
