[0002] During the processing of semiconductors, the tin ribbon needs to be punched into multiple micro solder pads to meet the needs of wafer bonding. In the existing technology, the tin ribbon punching is generally performed manually. This manual punching method is inefficient and has high labor costs. In addition, manual punching is affected by the workers' proficiency, and the punching accuracy is not high, which easily leads to material waste.

[0003] In the utility model with Chinese patent publication number CN211803298U, a punching mechanism for solder sheet processing is proposed. The punching mechanism for solder sheet processing drives the tin ribbon on the tin ribbon roll to move in the horizontal direction through the tensioning part, and transports the tin ribbon to between the punching die and the material connection part. The punch on the punching die punches the tin ribbon into solder sheets from bottom to top, and pushes the solder sheets into the material connection part, thereby completing the automated punching of the solder sheets, improving the punching efficiency, ensuring the punching quality, and reducing the production cost. However, the applicant found that the production efficiency of the existing technology can be further improved, so the utility model proposes a three-solder sheet punching die. Utility Model Content
