RF radiation is a type of radio frequency that can interfere with nearby electronic equipment, causing unreliable or unpredictable performance. To avoid problems with these fields, RF and EMI shielding are used to shield and protect against unwanted signals and interference.

Contacts, fingerstock and gaskets are all components which can be used as part of effective RF and EMI shielding solutions. Contacts are metal pieces that are soldered or bolted onto a circuit board or surface to enable the connection between two or more circuits. Fingerstock is a conducting material used to form a gasket-like shape which is designed to act as a barrier between two components and prevent unwanted electromagnetic interference. Finally, gaskets are a type of advanced material which are designed to create a seal between two surfaces, providing a conductive/highly conductive path around an enclosure or system.

3020602 is a commonly used contact material in the manufacture of RF and EMI gaskets. The contacts are formed from polyester air filtration material, coated with an adherent metal on both sides for an effective, reliable electrical connection. The contacts are suitable for mechanical and electrical requirements when used in application for RF shielding. 3020602 contacts are typically electrically conductive and some mechanical strain relief/hardness variation may be needed to ensure sufficient connection.

For RF and EMI shielding in fingerstock form, 3020602 material can be cold-formed into a custom-configured, interlocking, gasket-like shape. It has excellent flexibility, conforming to the desired profile, yet providing superior compression characteristics. In applications requiring conformable shapes, 3020602 fingerstock gaskets provide excellent shielding performance and excellent EMI/RFI attenuation.

Finally, when used as part of a gasket system, 3020602 provides an optimal air gap in the form of a conductive or highly conductive path. The air gap allows unwanted RF and EMI radiation through the gap, but does not permit the compromise of other components due to contact with the interior components. In this type of application, 3020602 gaskets have the added benefit of eliminating the need for costly electrical connections and expensive enclosures.

In summary, 3020602 contacts, fingerstock and gaskets are often used in RF and EMI shielding solutions due to their effective electrical connection, flexibility and conductive/highly conductive path for shielding. These components provide superior shielding performance and protection against unwanted electromagnetic interference.
