What is EMC?

What is electromagnetic compatibility?

? Electromagnetic Interference (Electromagnetic Interference, EMI): electromagnetic energy generated when the device works “chaotic strings of doors”, interfering with the normal work of other equipment, such as Bluetooth headset suddenly disconnected? It may be a nearby microwave oven “interference”!

? Electromagnetic Susceptibility (Electromagnetic Susceptibility, EMS): the device's “anti-jamming immunity”, such as cell phones in the subway station signal full grid without lagging, is a strong performance of anti-jamming!

?? Why is it super! ?? Why is it super! Heavy! Why is it so important?

1?? Life-saving level of stability: medical equipment, car navigation, once the interference, the consequences do not dare to think!

2?? Say goodbye to “equipment fighting”: a bunch of electrical appliances at home at the same time, do not fight in order to live in harmony!

3?? Global pass: not up to standard? The first thing you need to do is to get your hands on a new product, and you'll be able to get it back!

?? How to test?

? Radiation emission test: to find out the equipment secretly “emitted” interference signals

? Immunity performance test: simulated lightning, base stations and other interferences, to see if the equipment can “withstand”!

?? How to “prevent interference” when designing?

- Space management master: rational layout of the circuit, add a shield to the equipment “physical isolation”

- Grounding + filtering: like putting “noise-canceling headphones” on the device to filter out noise

- Material black technology: shielding materials, special filters, from the source to kill interference

?? Life in the “EMC rollover scene”

- The old microwave oven, WiFi signal directly disappeared

- Hospital equipment is interfered with, ECG data directly “jump”

- Car navigation suddenly died, almost missed the intersection...
