Copper foil is a negative electrolytic material, which is a continuous metal at the bottom of the circuit board. It is very thin and can be a PCB conductor. Generally speaking, it is stuck on the insulation layer, and the corresponding protective layer is formed on the surface through the printing process, and then a circuit pattern is formed through corrosion. What is copper foil? Now let me share with you in detail.

1、 Characteristics of copper foil

Briefly speaking, the copper foil has the characteristics of low surface oxidation, which can bond with different substrates. For example, various metals or insulating materials have a wide range of temperature applications.

For electronic grade copper foil, its purity is generally 99.7% or higher, and its thickness is generally in the range of 5um to 105um. It can be said to be the basic material in the electronic industry. With the rapid development of electronic information related industries, this electronic grade copper foil has a large usage.

2、 Performance advantages of carbon coated copper foil

1. Copper foil can improve the consistency of the use of the battery pack, which can substantially reduce the cost of battery composition.

2. The adhesive force between the active material and the collector fluid can be greatly improved, and the corresponding cost of manufacturing the electrode plate can be greatly reduced.

3. Copper foil can effectively reduce the polarization situation, thus improving the corresponding magnification and gram capacity related parameters, and improving the performance of related batteries.

4. Copper foil can well protect the collector fluid, thus can well increase the service time of the battery.

3、 Use of copper foil

Copper foil can be used in electromagnetic shielding and related anti-static applications. The conductive copper foil is placed on the substrate of the plate and then combined with the metal substrate, which can show good conductivity. Not only that, it can also provide related electromagnetic shielding effects. Our common classifications are self-adhesive, double conducting and single conducting copper foils. Moreover, these products are widely used in industrial calculators, related communication equipment, as well as civil televisions and video recorders. At present, the demand for electronic copper foil in the world market is increasing.
