Copper foil is a kind of electrolytic material. It is a thin layer
and continual metal foil which settle in the basal layer of the
circuit board. Copper foil is used as electric conductor of PCB. It
is easy to glue in the insulating layer, accepts print protection
layer and then forms circuit pattern after corrosion. Copper foil
sheet is made of copper and other metal in accordance with certain
proportion. It is well-suited to hotel, Buddha in temple, gilded
signboard, tile mosaics, crafts, etc. We supply rolled copper foil
and electrolytic copper foil. Rolled copper foil is widely applied
to calculators for industrial use, telecom equipment, QA equipment,
lithium ion battery, civil television, VCR, CD player, copier,
telephone, air conditioner, automotive electronic components, game
machine, etc. Electrolytic copper foil is called "neural network”
of transmission and communication for signal and electricity of
Copper foil has lower surface oxygen, which can attach to all kinds
of base, such as metal, insulation. It can be used under a wide
range of temperature. Copper foil has lower surface oxygen, making
it be capable of attaching to all kinds of base materials, such as
metal, insulation, etc. It can be used under a wide range of
Rolled Copper Foil
Rolled copper foil is widely applied in computer for industry,
telecom equipment, QA equipment, lithium ion battery, civil
television, VCR, CD player, copier, telephone, air conditioner,
automotive electronic components, and game machine, etc.
Rolled copper foil is widely used in electromagnetic shielding and
anti-static, to put the copper foil to the substrates and connect
with the metal base. Copper foil for sale is characterized by good
conductivity and offer effect of electromagnetic shielding.
1.High stick active substance
2.Good strength of extension
4.Scope of thickness for available micron
5.Comparing to electrolytic copper foil, the process of rolled
copper foil is harder.
6.Rolled copper foil has feature of lower surface oxygen. Copper
foil can attach to all kinds of base, such as metal, insulation.
Rolled copper foil has wider.
Thickness is between 0.1 mm and 0.01mm
Electrolytic Copper Foil
Electrolytic Copper Foil is an important material to make CCL and
PCB. Nowadays, with the rapid development of electronic information
industry, Electrolytic Copper Foil is referred to as the neural
network to connect electronic products signal and power
The production process of Electrodeposited Copper Foil is very
simple. There are three main processes: Solution to foil,
appearance dealing, products cutting. The process of Electrolytic
Copper Foil looks like simple, but it gathers electron, machine,
electrochemistry and it is a production process with strict request
on production environment.
