Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) - Contacts, Fingerstock and Gaskets & Application Field & Working Principle

Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) are forms of interference that occur when different electromagnetic waves interact with each other. RFI is generated by radio signal sources, such as radios or mobile phones, and EMI is generated by electronic devices such as computers, cell towers, or other emitters of electromagnetic energy. RFI and EMI can interfere with the ability of devices to communicate with each other, which can lead to service disruptions, data corruption, and other communication errors.

In order to minimize the effects of RFI and EMI, specialized shielding materials such as contacts, fingerstock and gaskets are used. These materials are designed to absorb, deflect, or redirect the electromagnetic energy away from sensitive electronic components. The use of these materials is especially important when designing components that need to be resilient to interference.

Fingerstock is made up of conductive metals such as conductive polymers or nickel plated steel. It is designed to create electrical contacts between two surfaces, or to provide a reliable seal between two objects. The contact points are used to maintain electrical continuity, while the gasket helps to prevent the spread of electromagnetic waves. Fingerstock is used in a variety of applications, from portable electronics to automotive electronics.

Gaskets are made of various materials, including rubber or silicone, and are designed to form a tight seal between two surface, to prevent air from flowing in or out. Gaskets are commonly used to reduce the spread of EMI or RFI, as well as providing protection from moisture and dust. Gaskets are also used to reduce the size of the package, by creating a more secure fit.

Contacts are made of metal or rubber and are designed to create a conductive path between two points. Contacts are used to create connections between two circuits, such as connecting a power source to a power filter. They can also be used in cases where multiple circuits need to communicate, such as connecting a control system to a piece of equipment.

These three materials, contacts, fingerstock and gaskets, are used in a variety of different applications, such as electronic shielding, EMI/RFI protection, and electrical connections. They are commonly used in industries such as automotive, medical, military, and aerospace.

When designing and constructing electronic components, the choice of materials used to shield and protect them from EMI or RFI can significantly affect the performance of the system. The use of specialized contacts, fingerstock and gaskets can provide an effective level of protection, as well as improve the overall reliability of the system.
