The quality of solder paste directly related to the welding quality of the product is good or bad. Printing speed, the cohesive force, back to the bridge after welding, erection, solder balling, wetting lack of false welding, Weld and other problems are related to the quality of solder paste, and therefore according to the manufacturers of equipment and process conditions to choose the right types of solder paste is very necessary. Dapeng high-quality tin solder powder and flux stability of the preparation of high production, high quality! 
 Features: 1, tin powder particles between the range of 25μ-45μ, publish uniform, low oxygen, for 0.33mm pitch products than the printing and reflow. 2, the flux content of 11.5 ± 1%, viscosity 750 ± 50kcps, collapse of <0.2mm; 3, the fine print, eliminating the printing process of omission, depression, and agglomeration. 4, wetting, solder full, even printed on the PCB board to maintain its viscosity after a long time, for different reflow soldering machine, a different temperature profile. 
 The use of solder paste: paste used in various electronic products, welding assembly and original device is the most widely used electronic assembly solder. 
 1, lead-free solder paste for green electronics assembly welding, the future is to replace lead solder solder, lead-free solder will be used in various electronic products manufacturing process. 
 2. 
 High-temperature solder paste for semiconductor device packaging, high-temperature welding process (multi-layer circuit board welding, etc.), components under high temperature welding. 

 3, low temperature solder used in soldering process (multi-layer circuit board welding, etc.) and lead-free electronics assembly welding. 
 4. 
 Paste special stainless steel alloy used in stainless steel 280-320 ℃ handicrafts made of welded stainless steel sheet and other materials (copper, tin, nickel and other metal) between the 
 Welding. 
 Lead solder, lead-free solder paste, green paste, 63/37 leaded solder paste, Sn-Bi solder paste environmental protection, Sn-Ag3.0-Cu0.5 green paste
