EMI/EMC Frames for shielding – the Electro Magnetic Compatibility

The EMC shielding
EM shielding's are used to protect against electromagnetic emissions, even directly on the PCB, to ensure reliable operation. A suitable shielding design can ensure the reliable operation of RFID applications. For more complex circuit designs and applications, the shielding frame can also be constructed in several sections, with different cells, to ensure that the individual components are shielded directly on the PCB.

The shielding not only protects against “incoming radiation,” but also prevents radiation from being emitted. An appropriate shielding design is therefore important to ensure the long-term reliability of the applications.

The EMI Design
EM shielding's for electronic housings, shielding frames for printed circuit boards, or even EM frames for testing rooms can feature different designs. One-piece frames for simpler applications, which are soldered directly onto the PCB, are used just as much as multi-piece variants made up of a frame and cover. With multi-piece variants, it is important to ensure that the connection between the frame and cover is as even and as large as possible. Only the best possible connection in the right design will achieve a correspondingly good shielding effect.

The material used for the shielding is also an important factor that must be taken into account for the shielding effect, as different materials have different shielding effects. Only by combining the right material with the right design a suitable shielding effect will be achieved.
