Miniature spring contacts with insulation coating

December 07, 2017 // By Julien Happich
The SCTAxD Series of spring contacts developed by ALPS Electric is aimed at board-to-board or board-to-device connection inside smartphones, wearable computers and other mobile equipment.

Compared to earlier Alps products, the SCTAxD Series achieves dramatically reduced insertion loss on connection of a device such as an RF antenna. This is due to laser welding of the tips of the two spiral springs, which ensures that signals do also pass through the support spring (sub-terminal). In addition, joining the tips of main and support springs improves robustness without compromising the original function and performance of the springs. And just like the SCTAxB Series, the SCTAxD Series has insulation coating applied to the spiral part of the spring, preventing shorting paths due to spring bending and thereby realizing stable high frequency performance. The 1.45×1.45mm square-shaped device can be mounted in any orientation, it supports currents up to 3A.
