Title:
COUNTERMEASURE FOR EMI
Document Type and Number:
Japanese Patent JP3528427
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make it possible to take a sufficient measure for a noise found after necessary devices are mounted without taking some measures beforehand and eliminate an installation space for the devices for settling the noise problem by coating a bus line of an information processing equipment with a composite magnetic body including soft magnetic powder and an organic binder.
SOLUTION: At least a part of a bus line 6 of information processing equipment is coated with a composite magnetic body 1 which includes soft magnetic powder and an organic binder. For example, an electromagnetic interference suppressor 11 which has a sheet-like composite magnetic body 1 is installed on the bus line 6 which connects a CPU 5 and an external circuit. The composite magnetic body 1 is constituted of metallic magnetic powder which has an oxide coating on the surface and an organic binder and has a shape of a sheet having two magnetic resonances. The electromagnetic interference suppressor 11 has a polypropylene resin layer 2 formed on one face of the composite magnetic body 1. And, a pressure sensitive adhesive layer 3, a mainly of polyvinyl alcohol, is formed on one face of the resin layer 2.
