Basic Knowledge of SMT, a Very Practical Surface Mount Technology of Electronic Components
The full name of SMT is Surface mount (or mounting) technology. SMT is the abbreviation of Surface Mount Technology, also known as surface mounting or surface installation technology. It is currently the most popular technology and process in the electronic assembly industry. Generally speaking, the specified temperature in the SMT workshop is 25±3℃. SMT Mounting Machine Solder Paste: When printing solder paste, the materials and tools required for preparation are solder paste, stencil, scraper, wiping paper, clean paper, cleaning agent, and stirring knife. The components of solder paste include: metal powder, solvent, flux, anti-sag agent, and activator. Its main components are tin powder and flux, with a volume ratio of approximately and a weight ratio of approximately 9:1. The flux starts to volatilize in the constant temperature zone and performs chemical cleaning operations; the main functions of the flux in soldering are to remove oxides, break the surface tension of molten tin, ...
