Sockets for ICs, Transistors

An intimate understanding of the physical principles underlying integrated circuits (ICs) and transistors is critically important for designing, servicing, and troubleshooting electronic equipment. These components feature a variety of specialized contact socket designs, allowing their consistent and secure connection to a PCB in a wide range of applications. In particular, reliable usage of 916716-2 application field and working principle sockets makes it possible to quickly establish electrical connections between an IC and an external circuit.At the core of 916716-2 application field and working principle sockets lies spring-loaded contact blades. These allow a reliable electrical connection to the IC or transistor when pushed into a through-hole on the PCB. Contemporary socket designs feature a range of contact blades that are either mechanically compliant or compliant with a standard bus technology. Relying either on the connection tension of the blades or on a physical locking mechanism, different sockets types provide an array of hold and insertion forces.The 916716-2 socket series (also referred to as “high-temperature metal-seal” sockets) offers a wide range of electrical and mechanical ratings. The good contact force, due to the resilient spring-action, allows for increased current paths in densely-packed electronic applications. Additionally, this design also benefits from excellent thermal transfer properties and tensile strength, and offers tight sealing against the environment and dust particulate.In terms of operation principles, the 916716-2 socket features a five-contact blade design, with four fixed contact blades and one movable blade. After the socket is inserted into the PCB, the inner spring contacts the movable blade and locks it in the groove. The spring pressure on the movable blade increases with the insertion force, providing an additional and reliable contact force for the IC element.The metal-to-metal use of the internal contacts also means that shorting is less likely to be an issue in this type of socket. Another advantage, in comparison with other socket designs, is the fast setup and minimal wiring time provided with 916716-2s. Moreover, with the broad range of service ratings available, this socket can be effectively used in many industrial, automotive, and civil applications.In conclusion, the 916716-2 socket series provides all of the core features and advantages needed for a secure and reliable connection between ICs, transistors, and other components, and a PCB. This socket employs spring-loaded contacts and electrically locking mechanisms for optimal reliability and increased service life. Thanks to the broad range of service ratings available, the 916716-2 socket is suitable for applications in many industries.
