Abstract

Abstract: Environmental protection has become the goal of global sustainable development. Analysis of the application of nano diffusion pipe in the local nitrogen protection welding process of wave soldering, By analyzing the amount of dross generated by nitrogen hydrodynamics, tin furnace structure, and nitrogen concentration, a device was developed to allow nitrogen to reach a certain concentration and maintain equilibrium at a local location. Through simulation software to simulate the distribution of nitrogen and combined with experimental verification, a reasonable range of nitrogen concentration was finally determined, and the purpose of saving solder, improving product quality and reducing cost was successfully achieved.

Key words: Nanoscale diffuser, Wave solder, Titanium alloy frame, Simulation, Nitrogen
