Solder paste isSMTAn indispensable material in processing, its quality determines the printing effect and welding effect. What are the general evaluation criteria for solder paste quality? What other factors can affect the quality of solder paste? Today, Shenzhen JJY Solder Paste Manufacturer is here to share with you the methods for judging solder paste quality and the influencing factors:1After the solder paste is printed, it is evenly distributed with strong consistency.2The solder paste pattern is consistent with the pad pattern, with clear edges. None......

SMTIn actual production and processing, there are many possibilities for incomplete melting of solder paste. Below, Shenzhen JJY Solder Paste Factory will briefly introduce to you the common causes and solutions for incomplete melting of solder paste:1When all or most of the solder joints are insufficiently melted after surface mount technology (SMT) processing, it may be due to the low reflow soldering temperature or the short reflow time. Solution: Adjust the temperature curve. The peak temperature is generally determined......

inSMTDuring the surface mount technology (SMT) processing, component displacement is a common problem, which may lead to a decline in product quality or even product scrapping. As electronic products become smaller and more sophisticated, forSMTThe requirements for surface mount technology are also becoming increasingly strict. Now, Shenzhen JJY Solder Paste Manufacturer will explain it to youSMTSix potential factors for component displacement in surface mount technology (SMT) processing: First, improper adjustment of the air pressure at the suction nozzle of the SMT machineSMTThe air pressure of the suction nozzle of the surface mount technology (SMT) machine during surface mount processing......
