Abstract
A multiple-tool ball bonder includes a first tool (50, 150) and a second tool (52, 152) mounted on a single head (82, 182) requiring only one vision system (78, 178), one positioning system (68, 168), and one computer system (56, 228). The ball bonder (44, 144) allows for the single head (82, 182) to create interconnections between semiconductor devices (10, 148) and lead frame fingers (12, 148) in a first direction with the first tool (50, 150) and the second tool (52, 152) allows interconnections in a second direction (40) without requiring additional equipment or processing runs.
