    摘要: An apparatus for forming leads of semiconductor devices includes a tie-bar cutting device for cutting tie-bars connecting adjacent leads in a lead frame on which semiconductor chips are mounted and which has unwanted resin burrs as a result of resin-sealing, a resin-burr removing device for removing resin burrs from the lead frame whose tie-bars have been cut, and a bending device for bending the leads of the lead frame whose resin burrs have been removed. After tie-bars are cut from a lead frame on which semiconductor chips are mounted, resin burrs are removed from the lead frame and the leads of the lead frame are bent.

    摘要: A molding apparatus has a fixed upper platen and a movable lower platen on which are secured an upper and a lower mold half, respectively. A cleaning device for cleaning the mold surfaces of the mold halves is installed on the upper platen, and the lower platen is open so that foreign matter will not accumulate atop it.
