Vacuum Etching Machine Acid Etcher Alkaline Etching PCB Production Line
Vacuum etching machine uniformity ≥90%, etching factor ≥3.5 times. The vacuum suction device makes the spray operating system generate negative pressure, forming a low suction force, absorbing the etching liquid rich in copper ions, effectively preventing the "puddle". Which can improve production efficiency, quality, etching speed and etching uniformity.
