Why Are Automotive Electronics Afraid of “Interference”? Understand in One Article How EMC Impacts Your Driving Safety
In daily life, have you ever encountered these situations?
When the mobile phone is placed next to the computer, the WiFi signal suddenly becomes weak?
When the electric bike is charging, there is noise in the radio?
The "culprit" of these phenomena may be the failure to meet EMC (Electromagnetic Compatibility) requirements!
What is EMC (Electromagnetic Compatibility)?
Simply put, EMC (Electromagnetic Compatibility) is the ability to make different electronic devices "coexist peacefully" in the same space. It contains two basic requirements:
01 Do not interfere with others (EMI)
The electromagnetic "noise" generated by the equipment during operation should not be too loud, affecting other equipment (for example: a poor - quality charger interferes with the radio)
02 Not be interfered by others (EMS)
The equipment should have a certain "anti - interference" ability and can still work normally in a complex electromagneticenvironment (for example: the hospital electrocardiograph is not affected by the mobile phone)
We can imagine EMC (Electromagnetic Compatibility) as a traffic rule: All vehicles (electronic equipment) must abide by the traffic lights (standard limit values), cannot honk randomly (generate interference), and at the same time, must have a good braking system (anti - interference ability) to avoid accidents caused by other vehicles suddenly changing lanes.
Three Elements of EMC (Electromagnetic Compatibility) Issues
Every EMC (Electromagnetic Compatibility) issue is like a "love triangle" drama, requiring three roles to perform together:
01 Interference Source
Devices that generate electromagnetic "noise", such as mobile phones, microwave ovens, electric vehicle chargers, etc.
02 Propagation Path
Channels for interference propagation, which may be through the air (radiation) or wires (conduction).
03 Sensitive Equipment
"Victims" affected by interference, such as radios, medical equipment, automotive electronic systems, etc.
Why is EMC Important?
EMC (Electromagnetic Compatibility), although a specialized field, directly impacts a product’s performance, reliability, and time - to - market. As regulations in various countries become increasingly stringent, proactively planning for EMC will be the key to a product’s success.
There are three fundamental techniques for solving EMC problems:
01 Shielding
Put a “metal jacket” on the device to block electromagnetic waves from entering or exiting. It’s like using a soundproof wall to block the spread of noise.
02 Grounding
Provide a low - impedance return path for interference currents. It’s equivalent to building a dedicated expressway for “electrical noise” to prevent it from running amok.
03 Filtering
Install an “electromagnetic sieve” on the power supply or signal lines, allowing only the required frequencies to pass through.

Vookey EMC Star Product——Conshield VK8101 Conductive Adhesive:
EMC Guardian for Precision Electronic DevicesConductive adhesive, as a functional adhesive, is increasingly widely used in the electronics industry. It can not only provide stable electrical conductivity but also achieve adhesiveness and sealing properties, making it an ideal choice to replace traditional welding and mechanical fixing. Our conductive adhesive products cover various material series such as nickel - carbon and silver - copper. The electrical conductivity and mechanical properties can be adjusted according to different application requirements.
For example: The Conshield 810X series of nickel - carbon conductive adhesives focus more on corrosion resistance and environmental adaptability, suitable for automotive electronics and outdoor equipment; The Conshield AIR series of silver - copper conductive adhesives are suitable for high - frequency signal shielding, featuring low resistance and high reflection characteristics; Two - component high - temperature curing conductive adhesives can meet the requirements of high - reliability packaging, such as in the aerospace and special fields. Whether it is for the fixing of flexible circuit boards or the shielding and packaging of sensor modules, our conductive adhesives can provide stable and long - lasting performance.
With the rapid development of automotive intelligence and electrification, the EMC (Electromagnetic Compatibility) issues of in - vehicle electronic devices have become increasingly prominent. Traditional metal shielding solutions are difficult to meet the demands of lightweight and high integration, while automotive - grade conductive adhesives have emerged as a more recommended option. Our conductive adhesive materials comply with automotive industry standards and possess the following advantages:
01 High - temperature Resistance
Adapt to the high - temperature environments of engine compartments and motor controllers.
02 Salt Spray Resistance
Pass rigorous anti - corrosion tests to ensure long - term reliability.
03 Waterproof and Shock - proof
Suitable for key components such as in - vehicle radars and domain controllers.
04 Lightweight
Compared with metal shielding covers, the weight is reduced by more than 50%.
In applications such as 4D millimeter - wave radars, intelligent seats, and battery management systems (BMS), our EMC shielding materials can effectively suppress electromagnetic interference, ensure the precision of signal transmission, and contribute to the development of intelligent driving technology.
In an era where electronic devices are increasingly dense, let Vookey join hands with you to jointly create a more compatible and reliable intelligent future!
