The emergence of EMI and EMC stems from the rapid development of electronic equipment market. With the miniaturization and intelligence of electronic equipment and the competitive pressure of the market, various manufacturers are trying to shorten the time of equipment design and development as much as possible, which leads to the problem of electromagnetic compatibility is particularly prominent. In order to deal with this problem, manufacturers must take a series of measures, including strict testing and control of electronic equipment.
EMI and EMC's solutions include isolation technology, filtering technology and shielding technology. Isolation technology is to isolate two circuits so that they will not interfere with each other; Filtering technology is to add filters around interference sources, which can absorb and eliminate electromagnetic interference between interference sources; Shielding technology is to add metal shielding around electronic equipment, which can reduce the influence of external electromagnetic signals on the equipment. These technologies can effectively solve the problems of electromagnetic interference and electromagnetic compatibility, and ensure the normal work of electronic equipment.
