New PCB Etching Process Rreplaces Hydrogen Peroxide with Ozone
A new printed circuit board (PCB) etching process uses with ozone to replace hydrogen peroxide used in the etching solution. The invention is said to be environmentally more friendly while also producing traces just 20µm in width. H2O2 processes are seen as having broad process windows, making etching harder to control. The new process from […]
