[0002] The baking equipment for circuit boards mainly refers to a printed PCB circuit board oven, also known as a PCB board oven, a circuit board oven, etc. Such equipment is mainly used for moisture-proof drying storage of PCB circuit boards to improve the product quality of PCB boards.

[0003] For example, the Chinese patent with the publication number CN218296592U discloses a circuit board printing and baking equipment, including a drying box. Heaters are fixedly installed at the left and right ends inside the drying box. A rotating shaft is rotatably connected to the center inside the drying box. A supporting device is arranged on the outer wall of the rotating shaft. The supporting device includes an upper supporting plate, a lower supporting plate and a clamping device. The upper supporting plate is fixedly installed on the outer wall of the rotating shaft. The lower supporting plate is fixedly installed on the outer wall of the rotating shaft. The clamping device is arranged inside the upper supporting plate. For this circuit board printing and baking equipment, when the driving motor is started, the rotating shaft rotates. The supporting device on the outer wall of the rotating shaft drives the internal circuit board to rotate inside the drying box, making the drying of the circuit board more uniform and improving the drying effect of the circuit board. By arranging a limiting device on the upper supporting plate, the limiting plate fixes the side wall of the circuit board, improving the stability of the circuit board during rotary drying and protecting it.

In view of this, we propose a baking equipment for circuit boards. Summary of the Utility Model
