[0002] The flexible circuit board production drying device is a key equipment used in the production of flexible printed circuit boards. During the production process, the drying device is mainly used to remove solvents and moisture on the circuit board to ensure the quality and stability of the circuit board. The drying device generally uses high-temperature airflow to heat the circuit board, and by controlling the temperature and time, the solvent and moisture on the circuit board can be quickly evaporated. In addition, the flexible circuit board production drying device also has the characteristics of high degree of automation, easy operation, energy saving and environmental protection. During the production process, the operator only needs to put the circuit board into the device and set the temperature and time parameters to automatically complete the drying process. At the same time, the device adopts an advanced hot air circulation system, which can effectively reduce energy consumption and reduce production costs. In short, the flexible circuit board production drying device is an indispensable equipment in the production of flexible circuit boards.
