[0002] Circuit board electroplating is a process of plating a layer of metal or alloy on the circuit board to improve the conductivity, corrosion resistance, wear resistance and aesthetics of the circuit board. The circuit board needs to be degreased before electroplating. Currently, circuit board degreasing is usually carried out by spraying degreasing agent. The main function of circuit board degreasing is to remove oxides, ink residual film and glue on the copper surface of the circuit, so as to ensure the bonding strength between the copper and the electroplated copper or nickel of the pattern.

[0003] In the prior art, the announcement number CN215508029U discloses a degreasing device for circuit board pattern electroplating. This technical solution can solve the problem that the degreasing agent after spraying cannot be recycled, which is easy to cause waste and increase production costs, but it has certain limitations: during the actual spray degreasing process of the circuit board, after flushing one side of the circuit board, it may be necessary to turn the circuit board over and clean it again, which is easy to reduce the degreasing efficiency. At the same time, it is necessary to frequently open and close the pick-up and placement door to pick up and place the circuit board, which is more troublesome to operate; and during the flushing process of the nozzle, the circuit board is easy to swing under the impact of the water pressure, and the friction between the circuit board and the placement rack is easy to cause damage to the circuit board.
