The term RFI and EMI stands for Radio Frequency Interference and Electromagnetic Interference. Interference can occur when signals from one electronic device are picked up by another electronic device, which can cause problems in signal transmission.

When dealing with RFI and EMI, there are three main components that help to protect electronic components from interference – contacts, fingerstock, and gaskets. Each of these components works in a different way to reduce the effects of interference and allow for reliable transmission of signals.

Contacts: Contacts are one of the most important components in RFI and EMI. They are used to connect different parts of the circuit, providing a reliable and secure connection. This connection prevents interference from being picked up by other electronic devices. Contacts are usually made from metal and can be anything from a simple solder point, to a complicated contact block. They are designed to provide a secure connection that will not easily break if subjected to vibration or other forces.

Fingerstock: Fingerstock is another important component in reducing interference from RFI and EMI. Fingerstock is a type of metal strip that is used to provide a secure connection between two components. It is often used in automotive and telecommunications applications to provide reliable connections between various electronic components. Fingerstock helps to reduce the amount of interference that is picked up by other electronic devices by providing a shield between them.

Gaskets: Gaskets are used in RFI and EMI applications to provide a physical barrier between two components. This barrier helps to reduce the amount of interference that is picked up by other electronic devices. Gaskets are usually made from rubber, foam, or other materials that are able to absorb vibration and reduce the amount of noise that is transmitted. Gaskets are particularly important in applications where there is a lot of vibration, such as in automotive applications.

RFI and EMI applications rely on each of these components to work effectively together in order to reduce the interference that is picked up by other electronic devices. The contacts provide a reliable connection between different components, while the fingerstock and gaskets help to reduce the amount of noise and vibration that is transferred. The use of these components together ensures that signals are transmitted reliably and without interference.
