SYCAMORE Contacts Harwin SYCAMORE Contacts are low-profile, single-piece SMT socket contacts designed for direct assembly to the PCB. These contacts use two terminals to balance on the PCB while the rest of the contact sits in a hole in the PCB. This design eliminates the outer shell typical on existing two-piece PCB sockets, and the three points of contact improve on existing SMT sockets by ensuring signal continuity. The beryllium copper base material and gold-plating finish offer durability of 500 mating cycles.
