Copper foil is an anionic electrolytic material, which is a continuous metal that is at the bottom of a circuit board. It is characterized by being very thin and can be a PCB conductor. Generally speaking, it is glued on top of the insulating layer, through the printing process to form a corresponding protective layer on the surface, and then through the corrosion and the formation of a circuit pattern. So what is copper foil? Let me share with you in detail below.
Copper foil characteristics
Simply put, the characteristics of copper foil is a low surface oxidation properties, it can be bonded with different substrates. For example, it can be used with a wide range of metals or insulating materials, and it can be used in a wide range of temperatures.
For electronic grade copper foil, generally its purity is 99.7% or higher, 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 accelerated development of electronic information related industries, this electronic grade copper foil has a large amount of use.
Carbon coated copper foil performance advantages
The first is that the copper foil can be very good to improve the consistency of the use of battery packs, so that from the root of the battery packs can be greatly reduced costs.
The second is that it can greatly improve the adhesion between the active material and the fluid collector, which can greatly reduce the corresponding cost of manufacturing the pole piece.
The third is that the copper foil can very well reduce the polarization situation, so as to improve the corresponding multiplication rate and gram capacity related parameters, and very well improve the performance of the relevant battery.
The fourth is that the copper foil can protect the collector well, which can increase the service life of the battery well.
Use of copper foil
Copper foil can be used in electromagnetic shielding as well as related anti-static has a good application, the conductive copper foil on the substrate of the plate, and then with the metal substrate for the combination, can reflect a good conductivity, not only that, but also to provide the relevant electromagnetic shielding effect. The main categories are self-adhesive, dual-conductive and single-conductive copper foils. In addition, these products are widely used in industrial calculators, communications equipment, as well as civilian television sets and video recorders. The demand for electronic-grade copper foil is increasing in the world market.
By the above simple introduction, I believe that everyone for the copper foil is what this problem have understood. This type of substance has a very wide range of directions of use and is a common material.
