Printed circuit board's cooling device and production line thereof

Printed circuit board's cooling device, it sets up in transmission track (30) of printed circuit board production line, and cooling device includes one access structure (10) and one fan (20). Access structure forms a both ends open -ended passageway to allow the transmission track to pass. The fan sets up in access structure, can the suction or blow off the air in the access structure. Above -mentioned printed circuit board's cooling device can accomplish the cooling process at conveying printed circuit board's in -process, need not to wait for, and the cooling effect is good, can avoid causing not good influence to product quality. 印制电路板的冷却装置，其设置于印制电路板生产线的传输轨道(30)，冷却装置包括个通道结构(10)和个风机(20)。通道结构形成个两端开口的通道，以允许传输轨道穿过。风机设置于通道结构，能够吸出或吹出通道结构内的空气。上述印制电路板的冷却装置能够在传送印制电路板的过程中完成冷却过程，无需等待，且冷却效果好，能够避免对产品质量造成不好的影响。
