Designated the 5802 Series, a 0.4-mm-pitch board-to-board connectors from AVX is presented as the smallest available, with a 0.8-mm stacking height and 3.2-mm width, including tails. The area beneath the connector is fully insulated, allowing designers to run
tracks beneath the device. The device uses a twin-rib structure and provides an audible and tactile “click” mating. A nickel barrier and solder-on receptacle contacts prevent solder wicking, while pinched-type dual contacts further enhance contact reliability.
