Ferric Chloride is a chemical solution commonly used in PCB etching to remove unwanted copper from printed circuit boards (PCBs). It reacts with the exposed copper, leaving behind the desired circuit pattern. Ferric chloride is widely used in DIY electronics and small-scale PCB fabrication due to its effectiveness and ease of use in etching precise designs.
