Abstract:
Equipment for attaching heat sinks to semiconductor modules, the equipment comprising:a base body; a built-up pad conveying unit mounted at the upper center of the base body, the built-up pad conveying unit having a plurality of built-up pads; a first heat sink supply unit that seats the first heat sink, from which a rivet is projected, on a built-up pad at a corresponding station of the built-up pad conveying unit; a semiconductor module unloading unit that seats the semiconductor module with the rivet through a hole in the semiconductor module after the built-up pad, on which the first heat sink is seated, is transferred one step; a second heat sink supply unit that seats a second heat sink with the rivet through a hole in the second heat sink, after the built-up pad, on which the combined first heat sink and semiconductor module are seated, is transferred another step; a riveting unit that works an end of the rivet of the first heat sink after the built-up pad with the first heat sink, the semiconductor module, and the second heat sink is transferred another step; a semiconductor product loading unit that loads the semiconductor products, which are connected to the first and second heat sinks after the riveting of a rivet machine, on a tray; and a tray conveying unit for transferring the tray from the semiconductor module unloading unit to the semiconductor product loading unit.
