Problems solved by technology

However, there is currently no test method for the activation temperature or activation time of the flux
[0004] The traditional method is to place the flux on the base metal plate and put it in a muffle furnace (wetting furnace), and set different furnace temperatures to investigate the activity of the flux and the way to remove the oxide film. However, this method has a slow heating rate and the furnace Inaccurate temperature (the same furnace may have different temperatures in different furnace chambers), cumbersome operation, and the inability to directly observe the process of film removal and flow laying, etc. These problems affect the test results of flux performance

Description

technical field [0001] The present invention relates to the technical field of brazing, in particular, to a device and method for measuring flux activation temperature and activation time; more specifically, to a device for measuring flux activation temperature and activation time, a device for measuring flux activation temperature A method of, and, a method of measuring flux activation time. Background technique [0002] Flux, including molten salt, organic matter, active gas, metal vapor, etc., except for the base metal and solder, generally refers to all substances used to reduce the interfacial tension of the base metal and solder. Due to the oxidation of the base metal during the brazing heating process, the welding cannot be performed. Therefore, flux is required to remove the oxide film, reduce the surface tension of the melting point, and promote the flow of the solder. Different brazing temperatures require different activation temperatures of the corresponding flu...
