EMI shielding is a barrier against electromagnetic interference, essentially protecting the electronics of a device or system. Typically consisting of a metal shield that absorbs airborne interference, either around the sensitive electronics of the device to protect it from other devices, or around the transmission electronics in the device to prevent emissions.

 

When an external signal reaches or originates from your device, the signal will be absorbed by the EMI shield, creating a current in its body that is absorbed through a ground connection or virtual ground plane. EMI shielding prevents random signals and waves from reacting between components that could adversely affect the device.

There are many types of EMI shielding materials. Experienced Newtop manufacturer  can help you determine the most effective shielding material for your product. Effective EMI shielding materials usually consist of a certain metal, copper, silver, nickel, and aluminum are all common metals in EMI shielding, and engineers often use a combination of materials to build the best EMI shielding for your specific product.
