Today INT METAL PRODUCTS CO., LTD will talk to you about the characteristics and uses of Copper Foil. Our Pure Copper Foil products are your perfect choice.
Copper foil is a negative electrolytic material, which is a continuous metal at the bottom of the circuit board. It is characterized by being very thin and can be a PCB conductor. Generally speaking, it is glued on the insulating layer, and a corresponding protective layer is formed on the surface through a printing process, and then a circuit pattern is formed by etching. So what is copper foil? Let me share with you in detail below.
Characteristics of copper foil
Simply put, the characteristic of copper foil is the low surface oxidation characteristic, which can be bonded to different substrates. For example, various metals or various insulating materials, etc., have a relatively 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 electronics industry. With the continuous acceleration of the development of electronic information related industries, this electronic grade copper foil has a large amount of use.
