• Copper foil is a foil form of copper less than the thickness of
150µm and there are two types, a rolled copper foil and an
electrolytic copper foil. Normally, a rolled copper foil is made
by rolling and annealing electrolytic copper continuously and
there is a restriction of the length. In contrast, an
electrolytic copper foil has no restriction of the length.
Copper Foils are mostly used for printed circuit boards,
flexible printed circuit boards, and lithium-ion batteries.
