Title: Arm-driving device
Inventor: KOIKE HIROKI
IPC: H01L21/52
Filed: 1986-12-05
Abstract: PURPOSE:To simplify a structure by a method wherein a scrubbing arm is swayed by using a pivotal support to a first guide groove as a fulcrum in such a way that a second guide groove is moved back and forth in the direction of its width while a travelling arm is moved back and forth by using the pivotal support to a side part in one direction of the scrubbing arm as a starting point. CONSTITUTION:When a guide rail 18 is moved back and forth in the upward and downward directions, a scrubbing arm 16 is swayed in the clockwise and counterclockwise directions around a fulcrum 16b1 at its edge part 16b. Through this swaying movement, a travelling arm 6 slides in the left and right directions inside guide grooves 3a and 4a of cross-roller guides 3 and 4 by using a pivotal support (fulcrum 16a1) to a side in one direction of the scrubbing arm 16 as a starting point. A collet 8 is moved back and forth in the left and right directions while it has sucked a semiconductor chip; the bottom part of the semiconductor chip and the mounting part of a lead frame are scrubbed while they are pressed by a prescribed pressure. Through thermal excitation by this scrubbing motion, both metals are diffused at this contact surface; their melting points are lowered to an eutectic temperature; these metals are melted and bonded.
