The utility model relates to the field of manufacture of PCBs, in particular to a device for cleaning a solder resisting layer of the PCB in the process of PCB production. The device, namely a fading and cleaning line of the solder resisting layer of the PCB, comprises a basic liquid medicine cleaning tank, a washing tank and a plate receiving tank which are arranged in sequence and form a whole by swinging frames arranged on the edges of all the tanks; the swinging frame is provided with a swinging motor, an inflating pump and a vibrating pump; a vehicle for transporting the PCB is arranged above the tank body; and the basic liquid medicine cleaning tank is internally provided with an ultrasonic device and a heating device. Compared with the prior art, the fading and cleaning line has the following obvious effects that: the fading and cleaning line can finish fading and cleaning by one time for ink including ink for plugging holes of the solder resisting layer of the PCB, has good cleaning effect, reduces unnecessary scraping of the PCB, reduces the production cost of an enterprise, has high degree of automation, saves labor and materials and greatly improves the production efficiency.
