Then use the paste according to the specific situations. Although SMT technology has greatly improved the efficiency and cost savings Pingdingshan solder alloy grain size, but we can find saved through the introduction and use of solder paste is not convenient. The most important point is the need to preserve the environment 0-10 ℃ Pingdingshan solder alloy grain size, which the transport requirements of a higher Pingdingshan solder alloy grain size, and manufacturers have had to increase the purchase of refrigerators and other related equipment investment. Zhengzhou City Fujie solder materials Co., Ltd. is a professional manufacturer of solder paste products, specialized factory Pingdingshan alloy grain size, which is accompanied by a new type of paste solder material SMT emerged choose Sn63 / Pb37 solder alloy components can be meet the welding requirements. Tin-lead solder paste is a solder powder, lead powder alloy composition modulation. Unleaded low-temperature tin powder and bismuth mainly silver metallic materials. Typically there will be lead-free solder. Copper powder with silver tone fluxes and other surfactants, thixotropic agent are mixed, the mixture formed a paste. Mainly used for reflow soldering of SMT industry among PCB surface resistors, capacitors, IC and other electronic components. No-clean solder paste, solder Fu Jie (online consultation), Pingdingshan paste supplied by Zhengzhou City Fujie solder materials Limited. 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.
