The surface of the copper clad foil is chemically etched to remove unnecessary copper conductors to form a circuit pattern.

   Process flow: entry → etching → new liquid washing → cascade water washing → DI water washing → exit

Specially for the etching of PCB marking, tthe whole CNC machining spraying nozzle frame with pressure regulation is used to control the pressure of each nozzle, and the spray pressure to the whole workpiece can reach the even and consistent spraying pressure during production

Compared with the traditional PCB etching machine, the alkaline vacuum etching machine is suitable for fine line etching requirements. The use of a vacuum etching machine makes the line pattern with line width/line distance ≤30/30um easier to realize.
