Production method of electromagnetic wave interference control seat, flat cable, flexible printed circuit board and electromagnetic wave interference control seat for high frequency signal

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.
