Abstract

PURPOSE:To constitute the title method in a manner that deburring is performed by reducing the generation of a deformation in a lead frame, by a method wherein a mask is provided on a part other than that of a burr and the burr is removed by applying a matter obtained by making dry ice small into a state of a particulate to the burr through the mask. CONSTITUTION:Lead frames which are held into a cassette and prior to deburring are taken out sheet by sheet and set up in a masking jig 15 by a loader 12. The lead frame 1 is placed between the masking jigs 15 by closing the masking jigs 15, chain 14 is turned and the lead frames 1 are set up to the masking jig 15 in order. When the lead frames 1 are conveyed to a deburring part 11, dry ice powder along with high-pressure air are sprayed on one side of the lead frame 1, for example, a surface side through a nozzle 10 and the dry ice powder through the next nozzle 10 is sprayed through the backside also and the burrs are removed. Then the lead frame is exposed under normal temperature while a U-turn of the lead frame is being performed, which is taken out of the masking jig 15 by an unloader 17 and held in the cassette.
