This three-day course is designed for technicians, operators, and engineers who need an understanding of all facets of grounding and shielding at the circuit, PCB, box or equipment level, cable-interconnected boxes (subsystem), system and building, facilities or vehicle levels. The course offers a discussion of the qualitative techniques for EMI control through grounding and shielding at all levels. It provides for selection of EMI suppression methods via math modeling and graphics of grounding and shielding parameters.
Our instructor will use computer software to provide real world examples and case histories. The computer software simulates and demonstrates various concepts and helps 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 grounding schemes and different "fixes" 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 "fixes" that may be used for aperture protection. .
There are also hardware demonstrations of the effect of various compromises and resulting "fixes" 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 "fixes" and illustrating their impact.
