[0002] The substrate is the basic material for manufacturing a PCB. Generally, the substrate is a copper-clad laminate. In the manufacturing of single-sided and double-sided printed boards, hole processing, electroless copper plating, electroplating copper, etching, etc. are selectively performed on the substrate material - copper-clad laminate (CCL) to obtain the required circuit pattern.

[0003] During the production process of the substrate, a water washing process needs to be carried out to complete the basic cleaning. For example, Chinese Patent Publication No. CN206100632U discloses a water washing device for a ceramic substrate, including a frame, a water heater, a ceramic substrate rack, a translation motor, a lifting motor, a moving frame, two sensors, a cold water tank, a hot water tank, and a single-chip microcomputer control system. The cold water tank and the hot water tank are installed side by side at the lower part of the frame, and a double slideway is installed in parallel at the upper part. The slideway is parallel to the ground. The single-chip microcomputer control system, the translation motor, the lifting motor, the moving frame, and the two sensors are used to control the movement of the ceramic substrate rack, solving the problems of poor cleaning effect and low efficiency of the existing equipment for cleaning ceramic substrates.
