Indirect imaging method for a bonding tool |
摘要 |
A vision system and method for use with a bonding tool that takes into account variations due to temperature changes and other nonrandom systemic effects. The vision system includes a cornercube offset tool having a plurality of total internal reflection surfaces, the cornercube offset tool located below the vision plane of the optical system; and an optical detector to receive an indirect image of the bonding tool through the cornercube offset tool. The method comprises the steps of providing a cornercube offset tool having a plurality of total internal reflection surfaces below a vision plane of the bonding tool; and receiving an indirect image of the bonding tool through the cornercube offset tool.
