With no-clean flux, preheat temperature should be controlled to what extent it is most appropriate? Practice has proved that the flux paste flux, no-clean flux after use, if based upon conventional preheating temperature (90 ± 10 ℃) to control, there may be adverse consequences. The main reason is a no-clean flux is a low solids content, how to use halogen-free flux flux, and its activity is generally weak, and it can hardly play the role of an active agent to eliminate metal oxide flux at low temperatures Which is good, as the preheat temperature increases flux, flux gradually began to activate. Free cleaning process to control the preheating temperature is another important aspect, generally require control at the upper limit (100 ℃) radical or requirements higher (by the Supplier Guiding temperature curve) and should have sufficient warm-up time for the solvent sufficiently volatile. Because of the strict limits of the solid content of flux and corrosion, welding. Its fluxing certainly limited. To get a good quality of welding, the welding equipment must also make new demands - an inert gas maintenance functions. In addition to the above measures no-clean flux | Xinyang Flux | FUJIE solder provided by Zhengzhou City Fujie Soldering Materials Co., Ltd. Zhengzhou City Fujie Soldering Materials Co., Ltd.
