AI Technical Summary
In the assembly process of electronic components, especially during soldering, the relative positional relationship between components is difficult to accurately control, resulting in the processing accuracy dependent on the operator, and the components are displaced due to heat deformation, making it difficult to adapt to large-scale operations.
A ceramic power device assembly graphite fixture is designed, including an intermediate bracket made of graphite, an upper pressure plate and a lower pressure plate. A storage tank and through hole are provided on the intermediate bracket, a pressing block and ventilation hole are provided on the pressure plate, a positioning hole and a positioning column are used for precise positioning, and a workpiece rack can be arranged to place the workpiece.
The components made of graphite are less deformation during the heating process. The workpiece is fixed by the weight of the component itself. The ventilation holes promote heat transfer, achieving rapid heating and fixation of the workpiece, which is suitable for large-scale processing.
