Help Controlling EMI and RFI

The idea of a shield is to protect users from dangerous elements that might surround it. An EMI shield provides immunity for a sensitive component from surrounding electromagnetic interference. An EMI shield is a bit different than other shields because it also prevents interference from being emitted from an electronic device. The primary method employed to protect from EMI and RFI is proper circuit design, placement of components, and grounding. Our team of engineers will help you make all the considerations necessary to produce optimal RFI gaskets and EMI shielding.

Shielding works by placing a Faraday cage around an electrical device. This is the fundamental principle for shielding against EMI. Depending on the electrical equipment, cages can be built from different materials. Commonly used materials include metal, conductive thermoplastics, and metalized plastics. Although conductive thermoplastics offer superior design and processing freedoms, other materials are better for specific needs. Our team will help you make all the considerations necessary to build proper shields and gaskets.

Additives are also used to help control both EMI and RFI. Metal substances are used, like stainless steel fibers, metal flakes, and copper fibers.  Metal coated materials are also used.

Controlling EMI and RFI is essential for the proper function of an electronic device. Let us help you keep your gear running well.
