What is copper foil?
Copper foil is a negative electrode electrolytic material and a continuous metal at the bottom of the circuit board. It is very thin and can be used as a PCB conductor. Generally speaking, it is attached to the insulating layer, and a corresponding protective layer is formed on the surface by printing process, and then a circuit pattern is formed by etching.
Copper foil can be used for electromagnetic shielding and related antistatic aspects. Putting the conductive copper foil on the substrate of the board and then combining it with the metal substrate can show good conductivity, and not only that, it can also provide related electromagnetic shielding effect. Our common types are self-adhesive, double conductor and single conductor copper foil. Not only that, these products are also widely used in industrial calculators, related communication equipment, and civil TV sets and video recorders. At present, the demand for electronic grade copper foil in the world market is increasing.
Copper foil thickness
Copper foil can be divided into rolled copper foil (RA copper foil) and electrolytic copper foil (ed copper foil), and the thickness of aluminum substrate copper foil is generally 1-8.
Oz (about 35um—350um).
Copper foil price
The price of conductive copper foil is generally about one kilogram, from 50 yuan to 70 yuan.
