ABSTRACT:
An improved input tube unloader assembly is provided for use with an IC handler structure so as to eliminate damage to IC packages and/or jamming of tubes. The input tube unloader assembly is comprised of a frame member and a pair of opposed main side plate members being supported on opposite ends of the frame member. Each of the pair of opposed main side plate members includes an upright section, a pair of transverse bracket portions joined to opposed sides of the upright section, and a tube guide portion mounted on an interior surface of the upright section. The tube guide portion is formed of an inverted T-shaped configuration and includes a longer vertical leg and a shorter horizontal leg joined integrally to a lower end of the longer vertical leg in its middle area.
