174394000 | Plural conductive layers | 9 |
20100096181 | ELECTROMAGNETIC SHIELD SHEET AND RFID PLATE - Provided is an electromagnetic shield sheet having an excellent electromagnetic shielding effect which can be sufficiently exhibited even when the sheet has a reduced thickness and a reduced weight. Furthermore, the electromagnetic shield sheet has an excellent molding efficiency and flexibility and can be used in a desired shape such as various shapes of a power supply box, an inner wall, or an electronic device for electromagnetic shielding. An RFID plate using the electromagnetic shield sheet is also provided. The electromagnetic shield sheet A has a polymer composition layer obtained by mixing a conductive material with a polymer material. The sheet A is formed by layering at least two of polymer composition layers | 04-22-2010 |
20100163299 | ELECTRONIC DEVICE AND HIGH FREQUENCY CIRCUIT BOARD THEREOF - An electronic device and a high frequency circuit board thereof are disclosed. The high frequency circuit board includes a first dielectric layer, a first signal line formed on the first dielectric layer, a second dielectric layer overlaying the first dielectric layer and covering the first signal line, and a first EMI shielding layer overlaying the second dielectric layer. The first EMI shielding layer has a gap formed thereon. The gap is formed at a position corresponding to the position of the first signal line. | 07-01-2010 |
20120267160 | ELECTRICAL SHIELDING MATERIAL COMPOSED OF METALLIZED STAINLESS STEEL MONOFILAMENT YARN - A yarn or multi-fiber formed of a plurality of micron diameter stainless steel monofilaments which have been rendered more conductive by one or more coatings of electrolytically-deposited metal or metal alloy materials. The metallized yarn provided by the invention has a very low electrical resistance, with consequent benefit in electrical performance, and is particularly useful as an RFI/EMI shielding material. | 10-25-2012 |
