<p>PURPOSE:To facilitate the fixing and removal of a stay for cutting down the replacement time thereof by a method wherein, while abutting a lead frame stay against abutting surfaces of frame stay fixture, the stay is aligned through the intermediary of this guide parts and then the stay vacuum sucked is fixed on the fixture. CONSTITUTION:A lead frame stay fixture 4 vertically movable is formed into a flat U-shape frame while both end upper surfaces of a lead frame stay 6 are abutted against the lower surface of both ends of the frame to present abutting surfaces 7 rectangular and recessed to fix the stay 6. Simultaneously, guide parts 8 abutting against the outer periphery of the stay 6 are formed on the step parts of respective abutting surfaces. Furthermore, suction holes 9 are made inside the fixture 4; opening ends are connected to a vacuum suction source not shown in figures; the stay 6 is fixed to the fixture 4 through the intermediary of the other suction holes 10 and the suction grooves 9; and then fixture 4 in this state is lowered to fix a frame 1 on a heat block 3.</p> |
