Electromagnetic shielding / EMC

Electromagnetic compatibility (EMC) is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment, by limiting the unintentional generation, propagation and reception of electromagnetic energy which may cause unwanted effects such as electromagnetic interference (EMI) or even physical damage in operational equipment. The goal of EMC is the correct operation of different equipment in a common electromagnetic environment.

How to get an electromagnetic shielding?

Copper is an excellent conductor. On polymer parts a thin layer of 20 to 50µm ensures strong performances. In order to prevent copper oxidation, a flash of nickel or silver can be added on top of the copper.
