Spring Fingers Provide Better Mobile Device Connections

Addressing mobile products, Tyco Electronics’ scalable spring fingers and a complete family of spring fingers are available in heights from 1.8 mm to 3.4 mm. and are mountable onto one single footprint. Their preload function nearly doubles the working area of a common spring finger and increases contact force by 0.2N. The components also have a dimple on the contact that boosts reliability. A backward-bent tip prevents the product from hooking by removing the sharp edge. On the back of the scalable spring finger, there is a pick-and-place area that supports auto assembly processes. The holes at the bottom increase soldering strength while reducing solder wicking issues. TYCO ELECTRONICS, Harrisburg, PA. (877) 623-4766.
