An integrated circuit device socket is spring-loaded to accept and capture a semiconductor device. As the frame springs relax, a device nest and capture arms lower the device down onto a grid of pogo-pins that probe the contacts underneath. Such pogo-pins pass through a dielectric grate, and are self-cleaning. The capture arms lock as they slide into constraint channels. Such prevents the device from escaping when a large aggregate force is applied from beneath by the pogo-pins. Each pogo-pin can generate 20-grams of contact force, and combine to as many as six pounds of force. To release the device, cams are used to force the frame springs open. The constraint channels clear the capture arms. The device releases when the capture arms move apart fully open.
