RFI and EMI - Contacts, Fingerstock and Gaskets

Electromagnetic interference (EMI) and radio frequency interference (RFI) can cause significant issues in engineering designs if not addressed. Problems such as voltage spikes, signal strength degradation, and shorting between conductors can lead to system outages and even fires. One way to reduce the effects of EMI and RFI is to incorporate shielding materials in the design of products or facilities. These materials provide a protective barrier between the environment and the electrical or electronic device being shielded.Contacts, fingerstock, and gaskets are all important components of electrical shielding systems. They are used in a variety of applications, including telecommunication, aerospace, defense, education, and medical, often in combination with other shielding materials. In order to properly shield a device or facility, it is important to understand how contact, fingerstock, and gasket technology work, and consider how their application can reduce the effects of EMI and RFI.

Introduction to Contact Technology

Contacts are electrical connections that create a bridge between two pieces of metal in order to complete an electrical circuit. In terms of EMI and RFI, contacts can be used to shunt noise away from sensitive components, thus providing an efficient means of grounding the noise. Contacts can be made from a variety of metals, including copper, aluminium, and tin.

Definition of Fingerstock Technology

Fingerstock is an elongated strip of metal, typically rectangular in shape, that provides an electrical connection between two conductive surfaces. The fingerstock has two conductive sides that are held together with an insulator. This design allows for a flexible connection that can be easily adjusted to create a snug fit between the two conductors. Fingerstock is usually used in applications that require a strong electrical connection, such as in electronic and telecommunications equipment.

Gasket Application and Working Principle

Gaskets are rubber or metal sheets, typically round or square in shape, that are placed between two surfaces to provide a snug fit and form a seal. In terms of EMI and RFI, the gaskets help to shunt any radiated noise away from sensitive components by providing an effective barrier between the device and its environment.Gaskets typically work in two ways. The first is by forming a conductive path that allows the noise to be diverted. The second is by forming a physical barrier that physically blocks the noise from entering the device or facility. The type of gasket used will depend on the application and the materials it is made from. For example, rubber gaskets work best in applications that require high vibration resistance, whereas metal gaskets are best suited for applications that require a reliable seal.

Conclusion

In conclusion, contacts, finger stock, and gaskets are effective tools for reducing the effects of EMI and RFI in engineering designs. They can be used in a variety of applications, from telecommunication to defense, and are typically used in combination with other shielding materials. It is important to understand how these tools work and how their application can reduce the effects of EMI and RFI in order to properly shield a device or facility.
