Etching

Printed circuit board (PCB) etching machine for double-sided or multi-layer printed circuit board (PCB) or thin copper etching uses with high precision.

All PCBs are made by bonding a layer of copper over the entire substrate, sometimes on both sides. Etching process has to be done to remove unnecessary copper after applying a temporary mask, leaving only the desired copper traces.

Though there are many methods available for etching, the most common method used by electronics hobbyists is etching using ferric chloride or hydrochloric acid. Both are abundant and cheap. Dip the PCB inside the solution and keep it moving inside. Take it out at times and stop the process as soon as the copper layer has gone. After etching, rub the PCB with a little acetone to remove the black color, thus giving the PCB a shining attractive look. The PCB layout is now complete.
