May adopt a different mold thickness Zhengzhou solder processing, production methods fifth winding, winding smooth operation in Jiaozuo can count the number of turns solder recovery in fully automatic control, when there will be winding uneven winding, uneven other adverse conditions in the production pay attention to these issues. The sixth step is to solder the package and test storage. Solder fume generated may cause pneumoconiosis handy tin solder wire, usually occupational hazards to the respiratory tract, lung is relatively large; if tin oxide, tin dioxide inhalation. Tin copper drain means the original point with the board, the non-wetting caused by a variety of situations. That sharp pull welding is completed, the solder joints irregular shape appears sharp, the aid may be solder wire activity is not strong impact on solder wetting and scalability affect the poor welding. That crude tin rough surface after welding. This phenomenon described indicators contain other metal impurities in the solder caused by high production does not meet specifications. Jiaozuo solder wire solder recovery _ Fu Jie (certified) _ Jiyuan solder provided by 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.
