Abstract:
A micro-manipulator apparatus for precisely positioning the tip of a wire bonding tool relative to a work piece, said apparatus comprising:a. a support structure,b. a manipulator input mechanism having an input control element moveable in a first, input coordinate system,c. a follower mechanism including a tool holder for holding a wire bonding tool and moving the tip of said wire bonding tool in a second, output coordinate system,d. linear bearing means joining said follower mechanism to said support structure in a manner enabling linear motion of said follower mechanism relative to said support structure, ande. coupling means joining said manipulator input mechanism to said follower mechanism whereby motions of said input control element in a first input direction in said first coordinate system are operable through said coupling means to effect corresponding motion of said follower mechanism, tool handler and tool tip in a first output direction in said second coordinate system.
