The Specific Role of Ferric Chloride in Printed Circuit Board Manufacturing
Ferric chloride (FeCl₃) plays a central role in the manufacturing of printed circuit boards (PCBs), primarily as an etchant used to selectively remove excess copper foil from copper-clad laminates, thereby forming the predefined circuit patterns. This etching process is an indispensable part of PCB manufacturing, and its success directly affects the electrical performance and reliability … Read more
