Reflow welding technology has many advantages over the traditional manual welding method. First, reflow technology enables efficient production lines. Through the use of automated equipment, reflow technology can greatly improve production efficiency, shorten production cycles, and reduce the occurrence of human factors and failures caused by human operations.

Second, reflow technology is very suitable for surface mount electronic components. Compared with traditional manual welding methods, reflow welding technology can more accurately weld electronic components, improve welding quality and product reliability. In addition, reflow technology can also enable the production of smaller and lighter electronic components, which is very important for the manufacture of micro electronic components.
