Description

Technical Field

[0002] In the field of semiconductor surface treatment, especially in the semiconductor photovoltaic industry, the surface tin plating process of electronic devices is closely related to the performance and reliability of the devices. The traditional tin plating process mainly adopts the hanging plating mode. This production process is not only cumbersome, but also relies on manual operation, including manual degumming, water spraying, electroplating, cleaning and unloading. This manpower-dependent operation method is not only inefficient, but also unstable in manual operation, resulting in large fluctuations in the film thickness control of photovoltaic semiconductors after electroplating, which is difficult to meet the requirements of high-precision production. The complete tin plating process requires the participation of multiple operators, which not only increases labor costs, but also increases uncontrollable factors in the production process, affecting product quality.

[0003] In the prior art, there is an automatic clamping steel belt transmission device with announcement number CN202989325U, which includes a steel belt and a spring steel clamp installed on the steel belt. The spring steel clamp includes a positioning part, an elastic part and a clamping part. The bottom end of the clamping part of the spring steel clamp cooperates with the circular hole above the plastic-encapsulated integrated circuit sheet to play a hanging role. However, the docking between the bottom end of the clamping part and the circular hole affects the automation efficiency, and simple docking cannot ensure the stability of the plastic-encapsulated integrated circuit sheet during the electroplating process.
