Toshiba Electronic Devices & Storage Corporation EMC testing laboratory receives ISO/IEC 17025 accreditation Technical Review

PublishTime：2021-07-02

●Conformity to standards stipulated by laws and directives is required when selling products such as IoT and in-vehicle equipment, where performance, integration and miniaturization are advancing at a rapid pace. In recent years, compliance to EMC (Electromagnetic Compatibility) is also becoming a requirement in many countries. It is necessary to address the EMC from the design stage of the equipment, and the need to confirm the EMC performance of the semiconductor devices by themselves is increasing.
●Toshiba Electronic Devices & Storage Corporation opened a semiconductor EMC testing laboratory in 2016. It recently received accreditation by Japan Accreditation Board (JAB) that it meets the "administrative requirements" and "requirements on technical capacity according to the type of tests" defined by the ISO/IEC 17025 standard.
●Many countries in the world use ISO/IEC certification to determine technical capability. By acquiring ISO/IEC 17025 accreditation the results of our EMC laboratory test results will be recognized and accepted worldwide.
●Overview
■In recent years, systems are advancing in sophistication, performance and miniaturization. This leads to devices becoming more prone to malfunction due to electromagnetic noise, leading to safety issues. In order to ensure electromagnetic noise immunity, it is necessary to check the EMC performance of the semiconductor components from the initial design stage of the equipment.
■In addition, with the adoption of EMC regulations in many countries and regions, it is necessary to satisfy these regulatory requirements to be able to distribute these products using these semiconductor integrated circuits.
■For automobile and in-vehicle equipment in Japan, the EMC regulations are referred to in the "Safety Standards of the Road transportation Vehicles" derived from the "Regulation 10" defined by the United Nations European Economic Committee. In addition, laws and regulations in various fields such as the "Electrical Appliances and Materials Safety Act" for home appliances, the "Law on Securing Quality, Efficacy and Safety of Products including Pharmaceuticals and Medical Devices" in medical equipment and others are applicable.
■EMC standards define the noise performance of electric and electronic systems such as automobiles, in-vehicle devices, consumer devices, and industrial devices. Specific standards are shown below:
▲CISPR ( International Radio Interference Special Committee)
▲IEC (International Electro technical Commission)
▲ISO (International Organization for Standardization)
■Also, since the 1990's, the SC 47 A (Subcommittee 47 A), WG 2 (Working Group 2) and WG 9 of IEC standardize the EMC modeling and measuring method of semiconductor integrated circuits So far, the following has been standardized.
■Emission standard - IEC 61967 series
■Immunity standards - IEC 62132 and IEC 62215 serie
■Simulation modeling standard - IEC 62433 series
■In recent years, the focus of discussion has shifted to the standardization of the IEC 62228 series which deals primarily with the evaluation of bus transceiver ICs operating in wired networks used by in-vehicle equipment.In the field of automobiles, it is necessary to have high reliability and real-time data transfer capability together with the ability to process large amounts of sensor, video and other data traffic for self-driving operation, such that ensuring EMC performance of an in-vehicle network cannot be avoid
■These standards do not define new measurement methods.Referring to already standardized procedures, tests for bus transceivers are specified in IEC 61967-4 (conducted emission 1Ω/150Ω method), similarly for IEC 62132-4 (conducted immunity DPI method), IEC 62215-3 (Conduct Impulse Immunity Non-synchronous Transient Pulse), and ISO 10605 (Electrostatic discharge).
■On the other hand, modeling standards of semiconductors for equipment and system design and development are being standardized as IEC 62433 series.
■Dealing with noise is becoming more difficult with recent systems due to functional complexity and miniaturization. The importance of reducing risk at the design stage by means of simulation is increasing, and standardization of semiconductor EMC models for implementation at the equipment level is called for.
■In Japan, discussions and submissions of proposals to IEC are made by the semiconductor group of JEITA (Japan Electronics and Information Technology Industries Association) consisting of the semiconductor subcommittee of the product technology standardization committee /integrated circuit product technology committee.
■To s h iba Electronic Devices & Storage Corporation participates in this subcommittee and provides experts to attend discussions at these IEC sessions.
