Liquid metal (LM) interconnects have angled features to reduce reflection loss and / or insertion loss of signals sent across the interconnects. The LM interconnects may be used to couple two electronic components, e.g., to physically and electrically couple an IC device and a circuit board together. One component has an array of LM wells, and the second component has a corresponding array of pins. The LM wells have tapered shapes, e.g., tapered sidewalls with LM within the sidewalls.
