[0023] When in use, first place the device at the designated position, and then support the device through the support seat 2 at the bottom of the base 1. Then the staff put on protective gloves and put the circuit board to be processed into the drain net 8 in the groove 21. Add the developer into the first cavity 3 through the liquid inlet component 5, and then merge the sealing plate 11 on the spray component 6 with the protective frame 10 to form a closed space.
