What is an RF Shield?

'RF' stands for Radio Frequency. An RF shield (Faraday Cage) is designed to protect electronic components from Radio Frequency Interference (RFI), sometimes referred to as Electromagnetic Interference (EMI). Objects that carry rapidly changing electrical currents, such as electronic devices, power lines, and even the sun, cause Radio Frequency Interference. These rapidly changing electrical currents create electromagnetic waves that can travel through the air and affect nearby devices.

Some electronic devices can also emit EMI and therefore must be shielded before they will past FCC testing.

RFI/EMI waves can interrupt and degrade the functionality and performance of an electronic device; for example, creating an audible buzz in audio devices like amplifiers, car radios, and telephones. RF shields work by attracting and diverting/reflecting electromagnetic waves around the devices encased within them. An RF shield may be used to prevent outside RFI from coming in, or to keep the RFI emitted by a shielded device from interfering with nearby components.

Fotofab has 40+ years experience designing and manufacturing RF Shields. We offer complete shield design services, we can work with your board layout, sketch or description to create a shield that is a custom fit for your board. There's really no need to struggle to cut out sheetmetal with scissors so your board can pass test when you can have a professionally designed and manufactured custom fit shield the next day. And then when your board does pass with flying colors, we can easily manufacture production parts from the tooling you have already paid for.
