AI Technical Summary

Technical Problem

Existing electroplating nozzles cannot achieve uniform liquid coverage on the material surface during the spraying process, resulting in uneven electroplated film thickness and affecting material performance.

Method used

A turbulence nozzle for electroplating cleaning, comprising a delivery pipe and a mixing nozzle, is designed. By setting a first nozzle, a second nozzle, and a third nozzle through the nozzle and providing a guide port on the middle side wall, the nozzle utilizes fluid momentum exchange to form a circulating flow, thereby achieving liquid mixing and a uniform spraying effect.

Benefits of technology

This achieves uniform coverage of the electroplated thin film layer on the circuit board surface, improving the electroplating quality and the overall performance of the materials.

Abstract

This utility model discloses a turbulence nozzle for electroplating cleaning, including a conveying pipe and a mixing nozzle installed on the conveying pipe; one end of the mixing nozzle is provided with a fixing block, the other end of the mixing nozzle is provided with a rear nozzle, the interior of the mixing nozzle is provided with a through first nozzle, the connection between the mixing nozzle and the rear nozzle is provided with a second nozzle, and the inner cavity of the rear nozzle is provided with a third nozzle; this utility model uses the pressure of a pump to drive the liquid into the mixing nozzle, accelerating it to a high speed. Around the guide port of the mixing nozzle, a low-pressure zone is generated due to the momentum transfer between fluids; this pressure difference induces the surrounding liquid to be drawn into the main jet, thereby forming a circulating flow; this high-speed main jet and the drawn-in liquid merge together and enter the mixing and diffusion zone together at a flow ratio of 1:4; achieving the purpose of stirring and mixing the solution without air intervention, effectively realizing the turbulence effect.
