The application field for basic sockets operating at high voltage and high current is mainly used in the field of semiconductor device testing, such as integrated circuits (ICs), transistors, thyristors, etc. These packages enable a convenient and simple installation of electronic modules in various electronic schemes.

The working principle of the socket is simple - it provides electrical connection between the device and the exit using contact sockets, which makes it possible to disconnect the module, or replace it with a different one. In the case of a transistor-specific socket, it comes with additional insulation material around the module inside the socket and has metal fingers on the side of the pins that touch the transistor and provide a secure connection. To keep the connection between the pins and the device consistent, a spring force is usually applied through the socket and maintains the pressure on the pins.

The primary function of most sockets is to provide electrical connections, and the application of the socket in module testing has obvious advantages compared with soldering. For example, the socket connection is extremely easy to remove and replace the module or component. Unlike soldered components, it can also improve the measure of insulation, and reduce the risk of solder bridge short circuit. It also has advantages such as lower cost and superior heat dissipation, which greatly increases the practicality of the socket. On the other hand, Solder can provide longer life compared with the socket for many industrial applications, while the flux inside the solder can optimize the impedance.

The most commonly used socket type in the application of transistors is a simple socket package, such as the one with a threaded metal nut. This application can be used for many types of transistors, however, for large transistor packages, which often have higher pin numbers and larger pin densities, a socket with metal clips is used, which provides greater stability and better pressure transfer.

In conclusion, sockets are a viable option for both integrated circuits and transistors applications, and should be considered when selecting a technology for module testing. It provides a secure, reliable connection, easy installation and removal, and is more cost-effective than soldering.
