PURPOSE:To improve foiling without lowering the temperature of lead frames on a stage by enabling a vacuum chuck foiling a given portion of the lead frames with cut metallic foil pieces held to rise in temperature like the frames. CONSTITUTION:A stage 13 holding intermittently-transferring lead frames 12 is made of a guide 23 and a cover 24 and an opening into which cut gold ribbon 4 foils pieces are inserted for the attachment thereof to the frames 12 is provided on the cover 24. A frame table 21 is placed on the side face of the stage 13, and a spool 5 round which gold ribbon 4 is wound, a vacuum chuck 9, a chuck holder 8, a transfer 10, a heating unit 11, a cam 22 and so forth are provided thereon. Thereby, the ribbon 4 is intermittently drawn out and cut to pieces using a cutter. The pieces are adsorbed by the chuck 9 heated to about 350 deg.C and pressed into the opening 25 and fastened to the frames 1. |
