The EMC (Electro-magnetic compatibility) includes EMI (Electro-magnetic Interference) and electro-magnetic immunity. The EMI standards for data processing equipment is the CISPR 22 issued by the IEC(International Electrotechnical Commission). Many nations are using this standard to prevent the radio equipment, TV and wireless facilities from the interference. The immunity standard is CISPR 24. The manufacturer shall voluntarily use the immunity standard to prevent the equipment from malfunctions. In Europe, the EMC Directive uses this standard. The focal point of EMC design has been moved from the shielding to the circuits design. The most importance is the control of impedance. The simulation software is important for an efficient design. Therefore, we have developed the software so called ACCUFIELD. Data processing equipment requires new materials to correspond the increase of processor speed. The flexible EM absorbing rubber sheet is being expected as an EMC material. We forecast that the recycable conductive plastics and the steel sheet with low surface-resistance will be required as the cabinet material in the future.
