Spring Fingers Spring fingers (also known as shield fingers, grounding springs, universal ground contacts or antenna clips) can be used in all types of small printed circuit board applications across all industries. A spring finger is a single contact, surface mountable internal connector with multiple functions on a PCB. Spring fingers can be used for antenna feeds, low voltage electrical connections and grounding or shielding. They are beneficial in preventing EMI noise and static caused by speakers, motors, microphones or any other type of connector that can cause vibration within an application. TE Connectivity (TE) continues to expand its spring finger portfolio offering a broad range of styles, heights, and materials to meet all customers needs.
