The solder paste reflow soldering process must be fully mastered to avoid batch reflow soldering defects. If one is not familiar with the reflow soldering process and has no understanding of the characteristics of solder paste reflow soldering, it is very likely to cause batch reflow soldering defects. Here, Shenzhen JJY Solder Paste Manufacturer will explain the solder paste reflow soldering process and soldering requirements: First, when the solder paste is placed in the heated reflow soldering environment, the solder paste reflow soldering process is divided into five stages.1It is used to achieve the required viscosity and screen printing......

The appearance of the filling cavities inside the reflow solder joints is related to the incomplete evaporation of the flux. Improper control of the amount of flux used during the welding process can easily lead to the phenomenon of filling cavities. The appearance of a small number of voids will not have a significant impact on the solder joints, but a large number of them will affect the reliability of the solder joints. Now, Shenzhen JJY Solder Paste Manufacturer will introduce the causes of voids in reflow solder joints:1The proportion of flux in the solder paste is too high, making it difficult for it to completely escape before the solder joint solidifies2"Preview"......

Solder paste soldering, as a bridge connecting electronic components and circuit boards, is of self-evident importance. However, when encountering problems such as solder paste not being soldered or missing solder, it not only affects production efficiency but may also deal a fatal blow to product performance. Today, JJY Solder Paste Manufacturer will give you an in-depth analysis of these soldering problems: Analysis of the reasons why solder paste does not apply solder: First, it might be that the solder paste has been used for a long time and has expired, affecting its quality. It could also be that the steel mesh is too thin, resulting in insufficient solder leakage. two......

Every solder paste manufacturer wants to acquire more customers and sell more solder paste. To achieve this, we must have a thorough understanding of the demands of relevant purchasers for the products. Next, Shenzhen JJY Solder Paste Manufacturer will talk about what the more common demands are:１Poor conditions such as Wuxi beads, continuous soldering or false soldering, and missed soldering. These conditions are relatively typical defects in electronic soldering, and generally, manufacturers will conduct relatively strict inspections and controls on them. Good quality should be guaranteed in production......
