Copper foil is an anodic electrolytic material, a thin and continuous layer of metal foil deposited on the bottom layer of a circuit board, serving as the conductor of the PCB. It easily adheres to the insulating layer, accepts the printing protective layer, and, after etching, forms the circuit pattern. Copper mirror test: A solderability corrosion test that employs a vacuum deposition film on a glass plate.

Basic Introduction

Copper foil is made by blending copper with a certain proportion of other metals. There are generally two types of copper foil: 90% copper content and 88% copper content. The size is 16*16cm. Copper foil is a versatile decorative material, commonly used in hotels, temples, Buddha statues, gold-plated signs, tiles, mosaics, and handicrafts.

Product Features

Copper foil features low surface oxygen characteristics, enabling it to adhere to various substrates such as metals and insulating materials, and boasts a broad temperature usage range.

Primary Applications:

Primarily used for electromagnetic shielding and antistatic, featuring conductive copper foil on the substrate, combined with metallic base materials, offering excellent conductivity and electromagnetic shielding properties.

Available in: Self-adhesive copper foil, double-sided copper foil, single-sided copper foil, etc.

Electronic-grade copper foil (purity above 99.7%, thickness 5um-105um) is one of the fundamental materials in the electronics industry. With the rapid development of the electronics information industry, the demand for electronic-grade copper foil is increasing significantly. The product is widely used in industrial calculators, communication equipment, QA equipment, lithium-ion batteries, consumer televisions, VCRs, CD players, copy machines, telephones, air conditioners, heating and cooling systems, automotive electronic components, gaming consoles, and more. The demand for electronic-grade copper foil, especially high-performance varieties, is growing both domestically and internationally.

Predictions by professional institutions indicate that by 2015, China's domestic demand for electronic-grade copper foil will reach 300,000 tons. China is set to become a major manufacturing hub for the global printed circuit board and copper foil industry, with a particularly positive outlook for the high-performance foil market.
