What Is a Spring Contact Probe?
A spring contact probe is an electrically conductive probe.
A spring contact probe can be used to inspect the continuity of printed circuit boards and electronic components without the need for soldering, connector connection, or other fixing. The shape of the probe can be selected according to the inspection target.
The spring-loaded structure allows the probe to make contact with the electrode to be inspected with an appropriate load.
Uses of Spring Contact Probes
A spring contact probes are used for continuity testing of electronic components.
The inspection targets include semiconductors, liquid crystal panels, circuit boards, connectors, capacitors, sensors, batteries, and other components.
In addition to simple inspections of disconnections and shorts in these components, spring contact probes can be used in a wide range of applications, such as current flow and high-frequency measurement. For example, to inspect ICs, spring contact probes are placed on the printed circuit board on the side of the inspection equipment and contacts the IC from above, enabling quality inspection without fixing it in place.
