Description

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 electronic products.

Features

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 temperature.

Description
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.
Features
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
3.High elongation
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.

Parameter

Thickness is between 0.1 mm and 0.01mm

Description

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 transmission.

Technological process

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.
