Electromagnetic interference interference sheet, flat cable for high-frequency signal, flexible printed circuit board, and electromagnetic wave interference suppression sheet

摘要

The conductive carbon and cumulative 50% cubic measure particle diameter the electromagnetic wave absorption in the adjacent electromagnetic field by using combining the spinel ferrite particle powder of 1 - 10 millimicrons, is superior, can obtain the electromagnetic wave interference control seat which is suited for high density mounting which at the same time controls reflection. After in order drying 10 - 100 millimicrons to become thick, applying the paint to which the conductive carbon and cumulative 50% cubic measure particle diameter make the spinel ferrite particle powder of 1 - 10 millimicrons disperse, can the electromagnetic wave interference control seat of this invention, obtain with the production method of this invention which thermal it pressurizes forms.
