  • Publication number: 20220403565
    Abstract: To provide an electromagnetic shielding material that has excellent shape following properties and can exhibit high electromagnetic wave shielding properties even in a deformed portion. A flexible magnetic film fabric (100) of one embodiment includes a plurality of first magnetic strips (10) extending in a first direction (11) and arranged substantially in parallel at a first pitch P1 along a second direction (12) orthogonal to the first direction (11); and a plurality of second magnetic strips (20) extending in a third direction (21) different from the first direction (11) and arranged substantially in parallel at a second pitch P2 along a fourth direction (22) orthogonal to the third direction (21). Each of the first magnetic strips (10) has a first average width W1, W1/P1 being from 0.05 to 0.98, and each of the second magnetic strips (20) has a second average width W2, W2/P2 being from 0.05 to 0.98.

  • Publication number: 20100294558
    Abstract: The present invention addresses the prevention of local entrapment of air between an electromagnetic interfere suppression sheet attached to an adherend and the adherend, and thereby achieve placement of the electromagnetic interference suppression layer at a constant distance from the adherend surface and obtain a uniform electromagnetic interference suppression effect across the entire attachment surface. There is provided an electromagnetic interference suppression sheet comprising an electromagnetic interference suppression layer that contains a soft magnetic powder and an organic binder, and a pressure-sensitive adhesive layer having a structured surface with the side opposite the structured surface being laminated in contact with the electromagnetic interference suppression layer, wherein a continuous groove reaching to the outer perimeter of the pressure-sensitive adhesive layer is formed in the structured surface.

  • Publication number: 20050233161
    Abstract: A thermosetting adhesive sheet with electroconductive and thermoconductive properties, which comprises a thermosetting adhesive sheet composed of a thermosetting adhesive composition comprising an ethylene-glycidyl(meth)acrylate copolymer and a carboxyl group-containing rosin, where crosslinking is formed between the ethylene of the copolymer by electron beam radiation, and having at least one through-opening region formed at a prescribed location, and further including a low melting point solder placed within said through-opening region(s) formed at the prescribed location(s).
