Abstract
A bonding device equipped with a heating block for heating, for instance, a lead frame upon which bonding is performed including vacuum suction nozzles, which are installed above the heating block so as to lift the lead frame, and an air-cylinder, which raises and lowers the vacuum suction nozzles. The lead frame is lifted from the heating block by the vacuum suction nozzles, thus being prevented from being overly heated by the heating block.
