It is well known that after solder paste soldering, there will be more or less some residues left behind, and these residues can easily have some adverse effects on electronic products, such as circuit short circuits, dielectric breakthrough, and component corrosion. Although most solder paste manufacturers have launched no-clean solder pastes to meet the requirements of electronic manufacturers, which has greatly reduced the harm of solder paste residues, many high-precision applications, such as automotive instruments and aircraft parts, still need to be cleaned even if the harm of residues is very small.......

Solder paste printing should be done wellPCBAIt is of vital importance. It has a direct impactPCBAThe overall welding effect. inPCBADuring the processing, how to do a good job in solder paste printing has become a problem that production managers must consider. The effect of solder paste printing is composed of four parts: steel mesh, solder paste, printing process and detection method. Now, let's take a look together with Shenzhen JJY Solder Paste Manufacturer: 1. Steel mesh The issuance of steel mesh must be based on certain criteriaPCBAThe layout of electronic components on the board is appropriately enlarged or reduced......

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......
