inSMTIn the surface mount technology (SMT) processing in factories, soldering is undoubtedly a very important processing step. If it is not done well during the soldering process, it will affect the entire processcIn the production of boards, even the slightest deviation can lead to substandard products. In severe cases, the products may even be scrapped. To avoid mistakes due to poor weldingmtThe processing quality has an impact, and the welding process should be given due attention. SoSMTHow to avoid defects during surface mount technology (SMT) soldering? Now, JJY solder Paste Manufacturer will give you a brief introduction......

False soldering isSMTThe most common drawback in surface mount technology (SMT) processing. Sometimes after welding, the front and back steel strips seem to be welded together, but in fact, they do not achieve the effect of being integrated as one. The strength of the joint surface is very low. On the production line, weld seams must go through various complex technological processes, especially in the high-temperature furnace zone and the high-pressure tension straightening zone. Therefore, the weld seams of virtual welding on the production line are prone to band breakage accidents, which have a significant impact on the normal operation of the production line.SMTFalse soldering in surface mount technology processing......

As is well known, after the electronic product board is tinned with a solder paste printer, it needs to be mounted through a surface mount machine and then reflow soldered. Such a complete production line has strict requirements for the time of each link; otherwise, there will be many poor-quality products after soldering. So, how long does reflow soldering need to be done after solder paste printing? Now, JJY Factory will explain::We know that after solder paste is printed, the active ingredients will volatilize after being placed in the workshop for a period of time. Tin......

Among the numerous solder wire brands, different brands have their own characteristics and advantages. It's hard to say which brand of welding wire is the best. However, from some fundamental factors, we can find some guiding principles for choosing solder wire. Here, the solder wire manufacturer will introduce it to you: First, choose the material. The main materials of solder wire are usually tin and lead, and there are also lead-free solder wires. The higher the tin content is, the better the electrical and thermal conductivity will be, but the cost will also be higher. Lead can be extracted.......
