What is EMC certification?

EMC certification is the standard for Electro Magnetic Compatibility, which is defined as "the ability of equipment and systems to work normally in their electromagnetic environment and not cause unbearable electromagnetic interference to anything in the environment."

What are the EMC design measures?

(1) EMC breaks down the system structure into relatively simple components: ① functional board; ② backplane; ③ rack and cabinet; ④ device layout, etc.

(2) When setting up a barrier between the interference source and the sensitive equipment, use: ① metal shielding; ② filters; ③ grounding printed lines; ④ trench protection, etc.

(3) When configuring protective devices at the entry and exit points (POE) of EMI to limit the entry of EMI through these POEs, use: ① filter; ② magnetic ring; ③ gasket; ④ common mode buffer amplifier; ⑤ optoelectronic isolation, etc.

(4) Use methods such as decomposition, boundary setting, leak plugging, and detection to verify and troubleshoot EMC design. The design principle of EMC is to take the above measures in a timely manner to achieve EMC indicators with the lowest cost.

The above is all about EMC certification. If you want to get more knowledge about EMC certification, please continue to pay attention!
