Test Methods for EMI Gaskets
The electronics industry uses EMI gaskets to create a Faraday Cage. It is produced out of boxes that are constructed with individual pieces of metal. Gaskets can build this cage through electronically bonding various metal pieces together. A gasket’s ability to bond can vary as much as 110 dB. Several factors dictate the ability of a gasket to bond, which includes:
- The conductivity of the gasket
- The conductivity of joint materials
- The conductivity of the surface of the gasket material
- The force being applied to the gasket against the joint surface
- The environment in which the gasket and gasketed joints operate
Once built, two primary methods are used to grade an EMI gasket: shielding effectiveness and transfer impedance. Testing both efficacy and impedance is essential for proper functioning gaskets. There are multiple testing methods available to help determine the status of EMI gaskets. To find out more about how to test for both aspects, please give us a call to discuss electromagnetic interference. Our team of engineers can custom build gaskets and shields to help keep your electronic gear safe from EMI.
