AI Technical Summary
Technical Problem
Existing silver plating processes for heat sinks in new energy vehicles suffer from high costs and inaccuracies. The corrosiveness of the silver plating solution in traditional processes leads to material waste and makes it difficult to achieve precise silver plating.
Method used
Precision positioning fixtures and PET film are used to apply film to the surface of the heat sink. The PET film is modified with reinforcing agents to make it resistant to acids and alkalis. Combined with automated equipment, precise silver plating is performed, and only the areas that need silver plating are treated.
Benefits of technology
This technology enables precise silver plating, reduces silver consumption, saves costs, and improves the yield rate and production efficiency of the process.

Abstract
The application discloses a precise silver plating process for a new energy automobile heat dissipation fin, and increases a precise positioning tool in a traditional silver plating process, so that silver plating is only performed on positions needing silver plating, thereby meeting the requirement of precise silver plating, and the use of silver plating is ensured through the design of the tool, thereby fundamentally reducing the cost of products. The application provides a precise silver plating process for a new energy automobile heat dissipation fin, increases a film pasting process in a traditional process, increases a reinforcing agent in a PET film, so that the PET film has acid and alkali resistance, and has high temperature resistance, so that the PET film can be soaked in a silver plating tank together with the heat dissipation fin, the heat dissipation fin covered by the film is isolated from a silver plating solution, so that only the positions needing silver plating perform silver plating reaction, other positions are in a protection state and are not affected, and finally, precise silver plating is realized, thereby reducing the amount of silver, saving cost, and using an automatic device in the process further reduces the process cost.
