EMC and EMI shielding: importance in electronics

Electronic devices are ubiquitous in our daily lives, and with the increasing quantity and complexity of electronic circuits, a significant challenge arises: managing electromagnetic interference, which can greatly impact the performance and functionality of devices.

Electromagnetic shielding and ensuring electromagnetic compatibility are essential aspects, achieved through mechanical solutions capable of protecting and ensuring the proper operation of electronic devices. For this reason, Elmec’s mechanical engineers work in synergy with electronic engineers to devise effective countermeasures and design high-performance installations.

EMI shielding: what is electromagnetic interference?

Electromagnetic interference (EMI) refers to a disturbance in electromagnetic signals caused by various sources, which can compromise the proper functioning of electronic equipment.

EMI can result in reduced performance, anomalies or signal degradation, data loss, or even serious system failures. EMI can be caused by both natural and artificial sources, such as power lines, TVs, radios, smartphones, and other communication or electronic devices. Additionally, natural phenomena such as solar flares or lightning can also cause electromagnetic interference.

What is EMC shielding?

Electromagnetic shielding (EMC) is a technique used to protect electronic devices from electromagnetic interference (EMI). Designing mechanical structures to shield electronics is crucial, especially when installations are placed in environments with high levels of electromagnetic interference.

Shielding solutions work by absorbing, dissipating, or blocking EMI, safeguarding electronic devices, and ensuring their proper operation even in the presence of external disturbances. Electromagnetic compatibility also refers to a device’s ability to operate in its environment without generating electromagnetic interference that could affect the performance of other devices.

To ensure the combination of electronic circuits and mechanical structures yields satisfactory and long-lasting results, it is crucial to address EMI during the design phase and make the best choices regarding design, materials, processes, and finishes. Alongside IP protection, heat dissipation, conductivity, aesthetics, and ease of use and maintenance, EMI shielding is one of the most frequently requested requirements for mechanical enclosures for electronics.

It is important to note that there are specific regulations concerning electromagnetic compatibility, which electronic devices must comply with to be marketed. Additionally, proper electromagnetic shielding enhances device performance, allowing it to operate more efficiently, reliably, and durably.

How Do we manage electromagnetic shielding?

Thanks to our extensive experience across diverse sectors, we fully understand the unique requirements of each electronic device. Our approach to electromagnetic shielding begins with custom design in close collaboration with the client. Together, we identify the specific needs of the product, the potential interference risks in its operating environment, and the tailored solutions available.

We use high-quality materials to ensure maximum shielding effectiveness, including selected metal alloys specifically chosen for their EMI attenuation properties. Additionally, we ensure that every system component (circuits, cables, connectors, etc.) is properly shielded, providing comprehensive protection against EMI. Every metal enclosure we produce undergoes rigorous testing before approval, using advanced simulation tools and real-world scenarios.

Moreover, given the constant technological and digital evolution and new challenges related to EMC shielding, we are committed to ongoing R&D to stay at the forefront of electronic protection techniques.
