Description

Refrigerating sheet welding device and method Technical Field The invention relates to the technical field of semiconductor welding, in particular to a refrigerating sheet welding device and a refrigerating sheet welding method. Background In the existing wire welding technology, manual welding is generally adopted, solder paste is heated by a soldering bit, and copper wires and copper pads are connected together by means of soldering flux. After welding, the soldering flux needs to be cleaned, the welding trace is obvious, the welding procedure is complex, manual operation is necessary, automation cannot be realized, and the temperature of the operation process is higher and generally exceeds 300 ℃. The welding efficiency is lower, and the reworking condition is more. When the connection between the plurality of refrigerating sheets is blocked, the seamless connection between the refrigerating sheets cannot be realized due to the requirements of wire space and welding wires, the space utilization rate is not high, and the simple multi-sheet combination requirement can be only realized.
