The main purpose of a PCB socket is to allow for the easy insertion, removal, and replacement of integrated circuits on a printed circuit board without soldering or desoldering.When a component needs to be upgraded, repaired, or tested, it can be quickly inserted or removed from the socket without soldering or desoldering. This is particularly useful during prototyping and development stages when frequent component changes are common. During the testing and debugging phases, engineers can quickly swap components in and out of sockets to identify faulty components or problematic connections. This facilitates efficient diagnosis and resolution of issues.
