Default Facts You Should Know about Heavy Copper PCB

Circuit boards including heavy copper PCB are produced with specialized etching and plating techniques. This includes high speed plating and differential etching. Originally, heavy copper features were structured by etching thick copper layer laminated board material, thereby causing uneven traces and improper undercutting. Major advances in plating technology have enabled heavy copper features to be formed using a combination of plating and etching. This has resulted in even sidewalls and easy undercut.
