MULTIPLE-DIRECTION WEDGE WIRE BONDING

In a general aspect, an electrical device assembly (e.g., a battery module) can include first, second and third electrical contact surface. The first and second electrical contact surfaces can be spaced from the third electrical contact surface in a common direction. The assembly can include a ribbon wire electrically coupling the first electrical contact surface with each of the second electrical contact surface and the third electrical contact surface. A first end of the ribbon wire can be wedge bonded to the first electrical contact surface with a first wedge wire bond, a second end of the ribbon wire can be wedge bonded to the second electrical contact surface with a second wedge wire bond, and a portion of the ribbon wire that is intermediate between the first and second ends can be wedge bonded to the third electrical contact surface with a third wedge wire bond.
