Preferably, the etching solution delivery pipe is equipped with filter.Some can be filtered out by filter to pump from etching
It is transported to the impurity of the etching solution in etching groove.
Preferably, the communicating pipe passes through articulation and spray supervisor's connection.It can facilitate unicom by articulation
Cross over pipe is replaced after pipe damage.
Preferably, the spray, which is in charge of, is connected by valve with the communicating pipe.It can be adjusted from communicating pipe by valve
It is inside passed to the flow that spray is in charge of interior etching solution, so as to adjust the pressure of the etching solution entered in etching groove.
Preferably, the spray, which is in charge of, is equipped with pressure gauge.Staff can be facilitated to observe at any time by pressure gauge
Spray is in charge of the pressure of interior etching solution.
Compared with prior art, it is an advantage of the invention that：The conveying of the etching solution of the etching section of the present invention is lost using 55KW
Pump is carved to complete, 55KW etchings pump is capable of providing the pressure and flow of bigger compared to traditional etching pump, by using this
55KW etches pumping for the mode of movement of the pump of traditional 8 smaller powers of use, is decreased while reducing maintenance rate
Pcb board is scrapped, meanwhile, etching solution, Neng Goubao are conveyed to etching groove one, etching groove two and etching groove San Tong method using a pump
It is identical with the pressure of the etching solution in etching groove three that card is transported to cutting one, etching groove two, improves the stability of etching.
