Abstract:
1. A method of providing electrical interconnection between solar substrates, the method comprising the steps of: (a) providing an XY table configured to carry a bond head assembly and a ribbon feeding system, the bond head assembly including a bonding tool, the ribbon feeding system being configured to feed a ribbon material to a position proximate the bonding tool through a ribbon guide of the ribbon feeding system, wherein the bond head assembly is configured to be moved along a substantially vertical axis, independent of the ribbon guide, such that the bonding tool of the bond head assembly is configured to form ultrasonic bonds; (b) ultrasonically bonding a portion of the ribbon material to a bonding location of a first solar substrate with the bonding tool to form a first bonded portion; (c) extending a length of the ribbon material continuous with the first bonded portion to a second solar substrate; and (d) ultrasonically bonding another portion of the ribbon material, continuous with the length of the ribbon material, to a bonding location of the second solar substrate with the bonding tool to form a second bonded portion.
