PRINT BOARD PERFORMING FUNCTION OF CONTROLLING GENERATION OF RF NOISE AND FUNCTION OF KEEPING FLATNESS AND ELECTRONIC DEVICE

摘要

PURPOSE: By constituting the housing with the metal material having the print board and electronic device is the conductivity the generation of the RF noise is controlled irrespective with the noise arriving in to connector.;CONSTITUTION: A laminating structure of wiring layer having the print board is the insulating layer and wiring pattern is had. The insulating layer and wiring layer are by turns laminated. A noise reduction device(2) is arranged in the top of wiring between the wiring pattern of the wiring layer and the connector(3). The wiring pattern having the domain putting one upon another from connector with the wiring between the noise reduction device does not have the domain putting one upon another with the other wiring pattern.;COPYRIGHT KIPO 2010
