PCB etching methods generally fall into one of two broad categories: wet and dry processes. For the home gamer, dry processes would include methods like milling out traces with a CNC router ...

It's worth noting that wet etching differs from dry etching techniques, such as reactive ion etching (RIE), which use plasma to remove material from a substrate. While both techniques are used in ...

While wet etching is generally simpler and less expensive than RIE, it has several limitations: Plasma etching, also known as dry etching, uses a plasma to remove material from a substrate. While ...

Both capacitively (RIE) and inductively (ICP) coupled plasma etcher with fluorine-based gases (CF4, CHF3, C4F8, SF6), BCl3, nitrogen, argon, and oxygen for anisotropic dry etching of Si-based ...
