  What is Red Glue? Red glue is a kind of polydilute compound, it will solidify after heating, the freezing point temperature is 150  ℃ , and the paste will become solid directly.       What is Solder Paste? Solder paste is a new type of soldering material that came into being with SMT.   It is a paste-like mixture formed by mixing solder powder, flux and other surfactants, thixotropic agents, etc.       The Difference between Solder Paste and Red Glue: 1. Red glue is red paste, and solder paste is gray paste.     2. The main function of the red glue is to fix the components on the PCB, so as to prevent the components from falling off during wave soldering. Red glue does not conduct electricity, it only plays a role in fixing. Solder paste is to solder the components on the PCB pads, and can complete the mechanical and electrical connection between the components and the PCB through the current.     3. The red glue is appl...

       In SMT processing, solder paste is an important raw material in production.   The selection of solder paste is very important, which is directly related to the quality of final products. So, what are the requirements for solder paste in SMT processing?       1.   Long storage life is required.  The solder paste can be stored for 3 to 6 months at 0 ~ 10 ℃, and there should be no chemical change during storage, and the phenomenon of separation of solder powder and flux should not occur,  and the viscosity and adhesion of solder paste need to remain unchanged.     2.  Good wetting performance is required.   In SMT processing, the active agent and wetting agent components in the flux should be selected correctly, so as to better meet the wetting performance requirements.     3. Long working life is required. Solder paste has been used for a long time in SMT processing, so the solder paste s...

      Solder paste is an indispensable material in SMT processing. The main function of solder paste is to form electrical connections between PCB pads and electronic components. There are different types of solder paste, so it is necessary to choose solder paste according to the type of customer's products. So what types of solder pastes are there?       1.  Leaded and lead-free solder pastes L eaded solder paste : As the name suggests, it contains lead in the ingredients. Although it is harmful to the environment and human body, the welding effect is good, the cost is low, and the mechanical strength of the solder joint is high. It can be applied to some electronic products that do not require environmental protection.     L ead-free solder pastes :   Its characteristics are that it is less harmful to human body and belongs to environmental protection products, but the mechanical strength of solder joints is lower than that of leaded s...
