[0002] There is a heating circuit inside the reflow soldering equipment, which heats the air or nitrogen to a sufficiently high temperature and blows it toward the circuit board with the components already attached, so that the solder on both sides of the components melts and then bonds to the main board. The advantage of this process is that the temperature is easy to control, oxidation can be avoided during the welding process, and the manufacturing cost is easier to control. For example, the Chinese utility model patent with patent publication number CN219292952U includes a welding machine, a movable box and a movable frame. The welding machine is movably installed with a movable frame inside, the inner side of the movable frame is fixedly connected to a fixed box, the top of the fixed box is embedded with a movable box, the inner side of the movable box is fixedly connected to a partition frame, and the inner side of the movable box is movably installed with a support plate.

In addition, two movable boxes that can be quickly removed can be used for continuous soldering processing to avoid the loss of energy caused by a long time of removing the electronic device circuit board.

In view of this, we propose a reflow soldering device for electronic equipment. Utility Model Content
