What are the SMT Processing Materials?
The quality and production efficiency of SMT processing is very critical to PCB, and the materials used for processing play a crucial role. So what are the materials in SMT processing? 1. S older P aste Solder paste is a paste made by alloy solder powder and paste sol dering flux. It is an indispensable solder material in SMT processing and is widely used in reflow soldering. Solder paste has a certain viscosity at room temperature, which can stick electronic components in designated positions, and then at the soldering temperature, with the volatilization of solvents and some additives, the soldered components are connected to the PCB to form a permanent connection. 2. S oldering F lux Soldering is the main process o f SMT processing, and soldering flux is an auxiliary material used in soldering. Its main function is to remove the oxides on the surface of the solder and the...
