Whether the welding point is bright is also a relatively important parameter in the welding process. Whether the solder joints are bright affects the appearance of the product. Nowadays, many product users have certain requirements for the appearance of products. It is suggested that we pay attention to the brightness of the solder joints when completing the processing of solder paste and welding. During the soldering process of solder paste surface mount processing, it cannot be guaranteed that the brightness of each solder joint will meet the requirements. So, what are the factors that directly affect the insufficient brightness of solder joints in solder paste surface mount processing......

As we all know, after the welding process is completed,PCBThere might be some impurities remaining on it. So, how to clean it? Here, the solder paste manufacturer will explain to you: First of all, you need to understand why cleaning is necessary. After the soldering process of lead-free solder paste is completed, there will be more or less residual impurities, and there are several types of residual impurities:a.Particulate pollutants are prone to cause electrical short circuits..Polar contaminants can also cause dielectric breakdown, leakage and corrosion of electronic component circuits, etc.c.Non-polar contaminants return......

For those who have just entered the solder paste industry, how to remember solder paste knowledge is a very important issue. Today, the solder paste manufacturer will teach everyone how to remember solder paste knowledge efficiently. First, familiarize yourself with various types. Generally speaking, solder paste can be divided into leaded solder paste and lead-free solder paste. Then, remember the different alloy composition types of this type of solder paste. Solder pastes produced by various alloy components have different melting points, but they can be classified according to their different melting points......

Solder paste can be printed either manually or by machine during use. Manual printing wastes more than machine printing, but it is also very easy to waste resources in machine printing. Although the wasteful use of solder paste is inevitable, some situations can be controlled. Now, let's have the solder paste manufacturer explain it to you: First, manual operation printing is more wasteful than intelligent printing. During the printing process, the solder paste will gradually dry. Experienced staff will be aware of this......

As a professional solder manufacturer, JJY is often asked whether halogen-free solder paste can replace lead-free solder paste. As for whether it is possible or not, the solder paste manufacturer will analyze the characteristics of halogen-free solder paste with everyone. The characteristics of halogen-free solder paste: This type of solder paste has high stability, does not produce halogens, and has no impact on the environment. After soldering with halogen-free solder paste, the residual debris appears transparent. It is suitable for reflow soldering processes with a wide window and can also be used for needle detection tests. It doesn't matter during wave soldering......
