Spring fingers (also known as shield fingers, grounding springs or universial ground contacts) are used in almost every small printed circuit board application. A spring finger is a single contact, surface mountable
internal connector. It provides an electrical connection and grounding from EMI noise and and static between a PCB and other electronic components, such as a secondary PCB, shield cam, antenna, or speaker.
TE Connectivity offers a wide selection of spring fingers in varying styles and sizes depending on the type of application.
