PURPOSE:To make it possible to stick closely and locate a member fast to a processing surface by providing apertures through the processing surface plate making respective parts of a pellet mounting part, etc., of a lead frame coincide with said apertures and by attracting a member by means of vacuum being applied through a vacuum port (the attraction may be performed by employing a magnet). CONSTITUTION:When a lead frame 1 is advanced on the surface of a processing surface plate 2 as indicated by an arrow, and one part of said frame is located at a processing head and said lead frame 1 is suctioned to the processing surface, apertures 2a, 2b are provide through the processing surface plate by letting respective one parts of a pellet mounting part, a leading part, a tie bar part and the like of the lead frame coincide with said apertures. With the situation, the member is sucked to the processing surface due to negative pressure at a reducing inlet 3. With the completion of the processing, the negative pressure is removed for having the number to itself before the lead frame is fed to allow the next processing to be performed. In case the lead frame is attracted and fixed to the processing surface, the situation is performed by making a permanent magnet and the like to approach to the processing surface plate. Further, for release, the lead frame is to be made isolated, and is forwarded. |
