Abstract
Abstract A wire bonder apparatus for bonding a wire to an electrical element at a plurality of bonding points and looping the wire between the points is provided with a bonding tool, which is mounted on an X-Y stage movable in an X-Y coordinate system. This X-Y stage comprises a compound reed assembly including a top frame supported on a first pair of flexible reeds, the first pair of reeds being supported on a second pair of flexible reeds hung from a base support, and a mounting platform mounted on a third pair of flexible reeds, the third pair of reeds being supported on a fourth pair of flexible reeds hung from the top frame. A bonding tool support arm is mounted on the mounting platform, a swing block being mounted on the end of the support arm by a fifth pair of flexible reeds, the bonding tool being mounted on the swing block by a sixth pair of flexible reeds, and means being provided for moving the bonding tool up and down on the swing block. A sub-base assembly supports the electrical element to which the wire is to be bonded, the sub-base assembly being movably supported, and a micromanipulator assembly being coupled to the sub-base assembly for moving it to initially position the electrical element under the bonding tool.
