Background

Reflow soldering machines, also known as reflow soldering machines or "reflow ovens," are devices that reliably join surface mount components and PCB pads together through solder paste alloys by providing a heated environment that melts the solder paste. The reflow welding machine consists of a control system (the control system adopts a PC + PLC + HMI (human machine interface) mode), a hot air system (a supercharged forced circulation hot air heating system, a special high-temperature motor, a speed variable frequency adjustable motor, a cold air system (a forced air cooling and water cooling structure, a cooling area temperature display adjustable motor), a machine body and a transmission system, wherein the supercharged forced circulation hot air heating system returns air back and forth to prevent the influence of air flow in a temperature area and ensure the temperature uniformity and the heating efficiency.
