AI Technical Summary

Technical Problem

Existing static acid cleaning tanks do not allow sufficient contact between the acid and the surface of printed circuit boards when cleaning them, making it difficult to completely remove impurities and affecting cleaning results and production efficiency.

Method used

A swing-type OSP pretreatment acid cleaning tank is designed. Through the cooperation of the push component and the reset spring, the placement rack drives the printed circuit board to swing in the tank, increasing the contact opportunity with the acid cleaning solution. It is also equipped with an exhaust gas treatment device to treat the exhaust gas during the cleaning process.

Benefits of technology

It improved cleaning effectiveness, shortened cleaning time, ensured the stability of the cleaning process and environmental protection, and increased production efficiency.
