RFI and EMI - Contacts, Fingerstock and Gaskets

Contacts, fingerstock, and gaskets are key tools used when meeting electromagnetic compatibility (EMC) requirements. Face to face contact is an essential element of achieving good EMC characteristics, especially in the shortwave frequency domain. Therefore, the choice of contact material is very important in the application of 0097091902.

Contact material selection should not only take into account the electromagnetic characteristics but also the physical and mechanical properties of the material. RFI and EMI shielding products have unique properties to meet the requirements for a wide range of applications. Some of these properties include low electrical conductivity, medium electrical conductivity, and high electrical conductivity; anti-static, anti-corrosion, and long life.

Fingerstock is thin sheet metal strip that is bent into a fingerlike shape. It is usually applied in pairs, one half with a round hole and the other half with a shuttered opening. Fingerstock is simple and easy to install, therefore it is widely used in many electronic products like keypads. The bent shape provides very tight contact pressure when two halves are put together.

Gaskets are key elements for EMC requirement. These elastomeric or metallic materials provide a layer of electrical insulation or shielding between conductive components, isolating them from each other. The most common application is between electrical components and their casings or containers such as computers, laptops, and cell phones. By isolating electrical components, gaskets provide EMC protection for these products.

The use of 0097091902 in the application field and its working principle have proven to be extremely successful in meeting EMC requirements of all phases of electronic device production and operation. Contacts, fingerstock, and gaskets are key elements to achieving the desired level of EMC. Therefore, it is critical that designers evaluate the properties of suitable materials when designing these products to ensure good results.
