EMI Shielding and EMI Shielding Gasket
Surprisingly enough, most handheld, electronic devices are in compliance with FCC standards and regulations. It is curious that something that doesn’t transmit sound is required to comply with the Federal Communication Commission. The reason for this anomaly boils down to switching devices. Any time that a circuit is switched or oscillated at a fast enough pace, it becomes capable of transmitting electromagnetic interference. Most handheld devices use diodes, which turn the device on or off at a rapid pace. This action results in the radiation of electromagnetic waves, that interfere with devices. 
You can run a simple experiment to witness this phenomenon by taking any traditional AM pocket radio and tuning it to a dead channel that only plays white noise. Once you have tuned the radio, pick up a TV remote control and press any of the buttons on the device. If you do this while placing the remote next to the radio you will hear a digital pulse train in the static noise. This noise represents the function of the diode switching currents to the infrared LED on the remote. When different buttons are activated, a different noise will appear from the radio.
With so many products that use switching devices, there is a large amount of electronic interference being produced on a day-to-day basis. Electronic interference can cause significant problems for important electronic operations. Shielding gaskets are designed to protect electronics from EMI. Shielding gaskets save components from harmful radiations, which can cause thousands of dollars worth of damage to a product. Metal gaskets act as shields that protect against undesired interference.
Shielding gaskets are made with a wide variety of materials, in order to match the needs of specific components and environments. These gaskets are implemented in a design in order to highlight and isolate a specific area of a device from another. Typically, a shielding gasket is placed between the shield housing and the mating surface of the device, in order to secure an electronic seal.
EMI Shielding
If you are in the market for an EMI shielding gasket, it is always best to contact a local EMI professional. Experts are able to discuss all aspects of electromagnetic radiation, and how to protect devices with shielding gaskets. There are so many different options available to stop EMI, so it is best to ask a professional for help. Protecting your electronics is the best way to save on repair costs!
EMI RFI Shielding- Purpose of EMI/RFI Shielding GasketsEMI and RFI are unintended consequences of electrical operations, but in certain cases EMI and RFI are purposefully generated.
