What is the difference between eless and electrolytic copper plating?
Eless plating (a.k.a. electroless) is ideal for rough surfaces and complex geometries because it offers a more uniform deposition. Eless coating processes may be a better option than an electrolytic process for a part with a small ID and long aspect ratio, for example. INTAs eless copper coatings are thin. To achieve a thicker coating electrolytic copper is used.
