What's the purpose of using conductive gasketing in EMI shielding?

The primary purpose of using conductive gasketing in EMI (Electromagnetic Interference) shielding is to ensure conductivity across joints. This type of gasketing is designed to create a conductive pathway that allows electrical continuity while sealing the enclosure against electromagnetic interference.

Conductive gasketing typically consists of materials that have conductive properties, such as metal-filled elastomers or conductive foams, which provide a reliable means to connect metal surfaces and maintain their electrical conductivity. This is crucial in applications where electronic components are housed, as it helps to prevent EMI leakage and protects sensitive equipment from external electromagnetic waves.

Moreover, while conductive gasketing can have additional benefits such as moisture sealing or oxidation resistance, its fundamental role in EMI shielding specifically focuses on maintaining the electrical connection necessary for effective shielding. By facilitating the flow of electricity across joints, conductive gasketing helps ensure that the electromagnetic shielding is continuous and effective throughout the enclosure, thereby enhancing the overall performance of the EMI protection system.
