The Multitest NanoKelvin socket was developed to meet the requirements of small pad QFN devices. It integrates the benefits of Kelvin technology with plunge-to-board capabilities. Proprietary Dura/Tecta coating combined with high contact force of 0.5 Newton at 0.4mm lead pitch and minimum scrub reportedly ensures electrical repeatability. The coating is said to guarantee socket lifespan of more that 1M insertions.

The socket uses contact spring blocks that allow for the exchange of contacted springs without the need for special tools or additional alignment. Applicable for packages such as QFN, QFP, and SOs with a lead pitch down to 0.3mm, the socket is suited to high-volume production of any Kelvin application such as mixed signal and analog devices.
