Good solder paste should have the following characteristics1It has a relatively long storage service life0-10℃Store below0-6One month. It is not prone to chemical reactions during storage, nor will there be a situation where solder powder and flux separate, and its viscosity and adhesion will remain unchanged.2It has a relatively long operating service life. Generally, it is stipulated that it can be placed at room temperature after printing or drop coating12-24For hours, its performance indicators remain unchanged.3After printing or gluing and before......

Generally, when we use solder paste, if it is not used up on the same day, we usually store it in the refrigerator if it will not be remade for two days and mark the time on it. This way, we can be more at ease. Shenzhen JJY is a well-known manufacturer specializing in customizing high-temperature solder paste. Now, let's have the editor of JJY explain it to you: To put it simply, medium-temperature solder paste is in contrast to high-temperature and low-temperature solder paste. It is called medium-temperature solder paste because its melting point is at high temperatures......

Solder paste is mainly a paste-like mixture composed of solder powder and flux, and is mainly used forSMTIn the processing industry, resistors, capacitors,ICWait for the electronic components to be solderedPCBOn the board. Solder paste is divided into leaded solder paste and lead-free solder paste. The main types of leaded solder paste and lead-free solder paste are as follows4Obvious differences in major aspects. When in use, the lead-containing solder paste should be thoroughly stirred, and then added to the printing screen according to the set amount for printing. For those using the dot injection process, the dot injection amount must be adjusted properly. During a long period of printing......
Details >We believe that solder paste is a soldering material. In the production process of electronic products, technicians play the role of first printing solder paste onPCBOn the substrate, components are installed with an installer and firmly welded through a welding furnace. If the solder paste is not used up on the same day and is not to be produced the next day, put it back in the refrigerator for storage and mark the time on the label. Introduction to Leaded Solder Paste: Leaded solder paste is composed of a mixture of soldering flux components and alloy components. Among the alloy components it occupies, tin and......

Solder paste printingMTCommon problems in processing technology: The quality of solder paste printing is very important. Solder paste printing is an important process flow. inSMTIn the surface mount technology (SMT) production process, the solder paste printing processing technology is a unified stage because it is due to the installation defects of many printed power circuits. When close intervals are applied, the problem is complex, resulting in tin Bridges between adjacent feet. Regulations for printing base steel plates1The specifications are precise and stable. And the steel mesh can have an excellent surface. Suitable and firm......
