What is electrodeposited copper foil:
Generally, copper foil is a foil form of copper less than the
thickness of 70µm and there are 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 because it is manufactured
under the process which is shown below. Especially, together with
world's top share is obtained for lithium-ion batteries, they are
used for flexible printed distributing boards, so their stable
performance have been winning approval.
