Abstract
An exemplary fluid circulating system includes a return pipe, a reservoir, a suction pipe, a supply pipe, a circulating pump, and a processing device. The reservoir is configured for containing a work fluid. The processing device is configured for processing a semi-finished printed circuit board using the work fluid. The circulating pump is configured for transferring the work fluid from the reservoir to the processing device. The suction pipe and the supply pipe are respectively coupled to an inlet and the outlet of the circulating pump. An inner diameter of the suction pipe is larger than that of the supply pipe. The return pipe is coupled to the processing device for delivering the work fluid from the processing device to the reservoir. The fluid circulating system can improve quality of the circulated work fluid.
