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.

PAGE 3DATA AND DEVICES /// SPRING FINGERS Box C Standard box and C type connectors both have simple geometry for easy application. Standard-flat Contact Pre-loaded Pre-loaded spring fingers are recommended when a stable electrical contact with minimal deflection is needed. The force change is minimized over the working range of the spring finger. Pre-loaded spring fingers are available in three scalable families. Pre-loaded Contact Y Ultra low profile, Y type spring fingers are used in applications where low effective heights are needed. Ultra Low Profile Types of Scalable Spring Fingers & Key Features Standard Scalable

A pre-loaded spring finger allows for the same amount of force with a smaller compression and provides a stable electrical contact with minimal deflection. These features are useful for applications with limited available height. Question 2 Answer 2 Which style of spring finger is best for my application? Spring fingers are typically some of the last pieces added to a board. The type used depends upon the height and space left on the board, but the decision is typically based on your design needs. ©2017 TE Connectivity Ltd. family of companies.

Answer 3 Yes, an application can have multiple spring fingers of more than one type. For example, simple C types can be used for grounding between the device and the PCB, while multiple pre-loaded spring fingers are used on the board for shielding or other simple connections. Question 4 What are the benefits of using a scalable spring finger? Answer 4 Scalable spring fingers use a common footprint, allowing easy design changes without requiring any extra space.
