Recently, many customers have been asking why some bubbles often appear at the solder joints when using lead-free solder paste for soldering and whether it has any impact on the products. Now let me tell you all that the appearance of bubbles in the solder joints is quite serious. If bubbles appear inside the solder joints, it not only poses a significant threat to the stability of the solder joints but also increases the probability of component failure. Today, JJY solder Paste Manufacturer is here to share with you how to solve the problem of bubbles produced by lead-free solder paste during soldering: Why do they occur during soldering......

Solder wire is a soldering material composed of two parts: tin alloy and flux. The alloy composition of lead-containing solder wire is divided into tin-lead and lead-containing flux. Environmentally friendly solder wire is made up of tin-copper alloy and lead-free flux. The main function of solder wire is to fill, repair or connect the main soldering material between two components. Then, can all materials be soldered with solder wire? Today, JJY solder Paste Manufacturer will explain to you: Soldering soldering......

SMTSome details of placement can eliminate some unfavorable conditions, such as solder paste printing and removing solder paste from the circuit board. Our goal is to deposit solder paste where it is needed. Misalignment or inconsistency between dyeing tools, dry solder paste, molds and circuit boards may lead to unsatisfactory solder paste at the bottom of the mold or during the assembly process. So, how can solder paste defects be prevented? JJY Solder Paste Manufacturer would like to explain to everyone: Use a small scraper to remove solder paste from the wrong printed circuit board.......

ForSMTFor surface mount technology (SMT) processing and soldering, many customers usually have requirements for the brightness of the solder joints. After all, the brightness of the solder joints can give us a refreshing feeling. However, during the soldering process of surface mount technology (SMT) processing, it cannot be guaranteed that the brightness of each solder joint will reach a shiny level. Well,SMTWhat are the reasons for the insufficient gloss of solder joints in surface mount technology (SMT) processing? Now, JJY solder Paste Manufacturer will explain it to you:1If the tin powder in the solder paste undergoes oxidation, it will affect the soldering......
