Contains more flammable solvent flux in flux, it must be noted that when the spray coating process. The presence of solvent vapors emitted spray deflagration certain risk, so the device needs to have good ventilation facilities and the necessary fire extinguisher. After preheating the coating flux, welding flux into the preheating Jiaozuo how to use, by preheating the flux to evaporate the solvent part, to enhance the flux activity. Tin liquid and the PCB must first detect the condition and then decide the operating speed, the proposed operating speed is preferably maintained in 3-5 seconds, if still can not exceed 6 seconds Xuchang welding flux procurement opportunities when good substrate or its operating conditions may need to be adjusted Flux formulation analysis, the firms seek to be the best help solve. Should be noted that when the spray nozzle adjustment, be sure to let the flux evenly distributed in PCB surface. Tin wave formation, PCB deformation, can effect a more uniform appearance. Jiaozuo how to use flux, solder Fu Jie (certification), Guizhou flux provided by the Zhengzhou City Fujie Soldering Materials Co., Ltd. Zhengzhou City Fujie Soldering Materials Co., Ltd. (www.fujiehanxi.com) (www.fujiehanxi.com) is Zhengzhou, electronics, electrical products processing leader, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness , the maximum meet customer needs. In FUJIE solder leadership with the staff warmly welcome all inquiries negotiations to create FUJIE solder a better future.
