PCB etching process is one of the major steps in the chemical processing of subtractive printed circuit board. It is the removal of copper, to achieve the desired circuit patterns. In PCB etching process, all copper is removed except the circuitry that is protected by the tin plating applied during the previous treatment in PCB manufacture. The tin is then stripped and the copper is cleaned and the newly prepared circuit is ready for solder mask.
