Representative implementations of devices and techniques provide interconnect structures and components for coupling various carriers, printed circuit board (PCB) components, integrated circuit (IC) dice, and the like, using tall and/or fine pitch physical connections. Multiple layers of conductive structures or materials are arranged to form the interconnect structures and components. Nonwettable barriers may be used with one or more of the layers to form a shape, including a pitch of one or more of the layers.
