Abstract:
1. An ultrasonic solar substrate bonding system comprising: a bond head assembly including a bonding tool for bonding a ribbon material to a plurality of solar substrates; a ribbon feeding system successively supplying portions of a continuous length of the ribbon material to the bonding tool such that the bonding tool forms ultrasonic bonds between the portions of the continuous length of the ribbon material and the plurality of solar substrates; and an XY table, the bond head assembly being carried by the XY table, the ribbon feeding system including a ribbon guide carried by the XY table, the ribbon guide being configured to guide the portions of the continuous length of the ribbon material from a ribbon supply to a position proximate the bonding tool, wherein the bond head assembly is configured to travel along a substantially vertical axis, independent of the ribbon guide, such that the bonding tool is adapted to form the ultrasonic bonds between the portions of the continuous length of the ribbon material and the plurality of solar substrates.
