The invention relates to the technical field of insulated gate bipolar transistors (IGBTs), and in particular, relates to a stackable and process-traceable tray in IGBT production, wherein the tray isused for placing transferred materials and comprises tray bodies, positioning pieces and identification pieces; the identification pieces store information associated with the materials; each tray body is provided with a first surface and a second surface, the positioning piece and the identification piece are respectively arranged on the first surface, and the second surface is provided with a positioning hole matched with the positioning piece; each positioning piece comprises a first positioning guide column and a second positioning guide column, and the first positioning guide columns andthe second positioning guide columns are diagonally mounted on the first surfaces of the tray bodies to guide stacking of the multiple tray bodies. The stackable and process-traceable tray has the beneficial effects that the tray bodies used for placing IGBTs can be stacked into multiple layers and then transferred, so that the IGBT production efficiency is improved, and the operation time is shortened; and through the arrangement of the identification pieces, material identification is rapid and convenient, and the function of process tracing is achieved.
Description
technical field [0001] The invention relates to the technical field of insulated gate bipolar transistors, in particular to a pallet that can be stacked and traceable in the process of IGBT production. Background technique [0002] The production of IGBT has multiple processes, which require different processes in multiple processes to complete the processing of the finished product; and processing between multiple processes requires the use of pallets for loading, transfer and transportation. Therefore, pallets are important The carrying tool affects the production efficiency of IGBT. IGBT (Insulated Gate Bipolar Transistor, Insulated Gate Bipolar Transistor) is a composite full-control voltage-driven power semiconductor device composed of BJT (Bipolar Transistor) and MOS (Insulated Gate Field Effect Transistor). [0003] The existing pallets do not have the function of product binding. Most equipment needs to take out the product and scan the code on the product, and read...
