RF interference (RFI) and electromagnetic interference (EMI) are two topics closely related to contacts and contact gaskets. The purpose of this article is to provide an overview of the application fields and working principles of these materials.Contact materials are used in a range of products and applications: from industrial machinery to consumer electronics. As their name implies, they are responsible for making electrical contact between two surfaces, for instance providing a conductive link between a processor and a memory module. The use of contact materials ensures that the electrical current passes efficiently and reliably between the two surfaces.Although contact materials are often made of soft metals like copper, lead, or brass, other materials are also used, such as silver, gold, stainless steel, aluminum, and even plastics. Usually, these materials are applied as thin layers that are sandwiched between two metal surfaces, wires, or printed circuit boards.Fingerstock, a type of contact material, is often used in applications where small amount of contact is needed. Fingerstock typically consists of a thin stainless steel or brass shim and is formed into a kind of loop that forms contact with the test pad. This type of material can be used in very small electrical components, such as switches and relays, as well as on the more complex circuits in larger equipment. It is also used in automotive and other transportation industries to provide a cost-effective contact mechanism between two surfaces.Gaskets, on the other hand, are made from materials formed into a specific shape to provide a physical and protective barrier between different hardware components or different types of circuits. Gaskets are used in a wide range of products, including computers, servers, automobiles, consumer electronics, and other industrial equipment. Some common materials used in the construction of gaskets are rubber, silicone, fiberglass, and Teflon. In most cases, gaskets are also applied with conductive sealants such as tin-plated copper.The working principle of contact materials and gaskets is relatively straightforward. Their main purpose is to form a highly conductive electrical connection between two surfaces, reducing any electrical resistance or interference that may arise between them. For instance, when fingerstock is used in a switch, the electrical current will be able to pass unimpeded through the closed loop of the fingerstock material. Similarly, gaskets ensure that the charge passes from one circuit to another without being affected by external sources of interference.In conclusion, contact materials and gaskets are two important components that play a pivotal role in ensuring the reliable transmission of electrical signals between two pieces of hardware. They are used in a range of products and applications and their working principle is relatively straightforward: reduce any electrical interference or resistance between two pieces of surfaces.
