Abstract

PURPOSE:To prevent the occurrence of a malfunction of a bonded lead frame due to vibration by forming a bridged racks between confronting grooves of a tray for a lead frame having right and left side walls having a plurality of horizontal grooves. CONSTITUTION:Grooves 23 extending horizontally are so formed on the confronting surfaces of confronting right and left side rectangular walls 21, 22 as to confront each other in such a manner that the interval between the walls 21 and 22 is maintained constantly via upper and lower rectangular plates 25, 26, racks 29 are inserted into the respective grooves 23, and lead frames are placed on the respective racks 29. Thus, even if the tray is vibrated, the vibration of the lead externally led of the lead frame can be eliminated, and the crack and fracture of the bonded wire can be prevented.
