Reflow manufacturer recycling - reflow maintenance, touch screen and OLED Forum
In SMT chip proofing or processing, a large amount of rosin flux in solder paste will remain in the inner wall of reflow soldering furnace and pipes in cooling zone after reflow soldering equipment has been used for a period of time.
a large amount of residue reduces the temperature control accuracy and welding quality of reflow soldering furnace.
