What is CNC PCB Milling and How Does it Work?
1. What is CNC PCB Milling? Traditional PCB manufacturing methods, such as chemical etching, have long been a staple in the industry. Chemical etching involves using corrosive chemicals, like ferric chloride or ammonium persulfate, to remove copper from a substrate. The process begins with applying a photoresist layer onto the copper - clad substrate. Then, […]
