ATI's Introduction to EMI / EMC course

Share |


    Technical Training Short On Site Course Quote

      This three-day course is designed for technicians, operators and engineers who need an understanding of Electromagnetic Interference (EMI)/Electromagnetic Compatibility (EMC) methodology and concepts. The course provides a basic working knowledge of the principles of EMC.

      The course will provide real world examples and case histories. Computer software will be used to simulate and demonstrate various concepts and help to bridge the gap between theory and the real world. The computer software will be made available to the attendees. One of the computer programs is used to design interconnecting equipments. This program demonstrates the impact of various EMI “EMI mitigation techniques" that are applied. Another computer program is used to design a shielded enclosure. The program considers the box material; seams and gaskets; cooling and viewing apertures; and various "EMI mitigation techniques" that may be used for aperture protection.

      There are also hardware demonstrations of the effect of various compromises on the shielding effectiveness of an enclosure. The compromises that are demonstrated are seam leakage, and a conductor penetrating the enclosure. The hardware demonstrations also include incorporating various "EMI mitigation techniques" and illustrating their impact.
      The instructor's text Designing Electronic Circuits for EMC will be provided to every attendee.
