[0002] The reflow oven is actually a large oven, but the temperature of each zone in the reflow oven can be adjusted separately. The solder paste on the circuit board is melted and soldered together with the SMT components through the change of different temperatures. The reflow oven relies on the hot air flow in the furnace to act on the solder paste on the solder joints of the circuit board, so that the solder paste is melted into liquid tin again, so that the SMT patch components and the circuit board are welded together, and then cooled in the reflow oven to form solder joints. The reflow oven process is to re-melt the paste solder pre-allocated to the printed circuit board pad to achieve the mechanical and electrical connection between the surface assembly component solder end or pin and the printed circuit board pad. The reflow oven is the last key process of SMT (surface mount technology). It is a real-time process control. Its process changes are relatively complex and involve many process parameters.
