Reflow soldering system

The invention discloses a reflow soldering system, comprising an intelligent reflow soldering system and a plate dividing device, wherein the plate dividing device is arranged at an outlet of a soldering furnace, and comprises two tracks, a PCB (printed circuit board) bracket and a direction adjuster; the two tracks are arranged in parallel; the PCB bracket is arranged between a transmission device and the two tracks; the direction adjuster is arranged below the PCB bracket, and is used for adjusting the direction of the PCB bracket; one track is used for conveying a faulted PCB; the other track is used for conveying a faultless PCB. According to the system disclosed by the invention, the detected faulted PCB can be independently distinguished, so as to facilitate maintenance of maintenance personnel; the faulted PCB can be taken out without data observation of special operation personnel; therefore, the working efficiency is improved, and manpower resources are saved.
