Abstract: PURPOSE:To shorten the time required for positioning by providing a means which measures three positions of the surface of an object of plane positioning at the same time and calculate the quantities of Z-axial, X-axial, and Y-axial rotation errors of the surface based upon a reference surface. CONSTITUTION:A mechanically movable part is equipped with a table 1 which is arranged movably in a Z-axial direction on an XY table when right-angled coordinates consisting of an X axis, Y axis, and a Z axis are used as reference coordinates. A 1st driving mechanism 2 moves the table 1 in the Z-axial direction and 2nd and 3rd driving mechanisms 6 and 7 move 2nd and 3rd support mechanisms 4 and 5 selectively in the Z-axial direction.

Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a wire bonding device and a wire bonding method, which can perform wire bonding with the optimum size of the wire. SOLUTION: Sparks are generated between the lower-end part of the wire, which is guided out from the lower end part of a capillary tool 12 and a torch 16, and a ball is formed. After this ball is bonded to the pad of a chip mounted on a substrate, the above described wire is bonded to the pad of the substrate by a capillary tool.

Title: Tape guide at die pickup part in die bonding device
Inventor: SAKAMOTO YUUJI
IPC: H01L21/68
Filed: 1983-05-04
Abstract: PURPOSE:To smoothly picking up a die by securely recognizing the die on an expand tape by a method wherein a part or the whole of the guide surface including the periphery of a vacuum hole is formed of rubber. CONSTITUTION:A recess 11 of a fixed depth is formed in a fixed cylindrical range around the vacuum hole 7 at the center of the guide surface 6. A rubber sheet 13 having the same thickness as the depth of the recess 11 and a hole corresponding to the vacuum hole 7 at the center is fitted in said recess. Even when a collet 5 abuts against the die D on the guide surface 6, the impact applied on the die D at this time is absorbed to the rubber sheet 13. Since the surface of the rubber sheet 13 irregularly reflects light, an optical system recognition device can exactly discriminates the boundary between the die D and the rubber sheet 13 and can therefore accurately lead the die D to the center position of a table guide 3.
