Specializing in the research and production of high-end copper foil
Electrolytic copper foil process
Electrolytic copper foil surface treatment is simply divided into three types by color: copper plating (red), zinc plating (gray), and brass plating (yellow). It can be seen that among the three surface treatment processes, cyanide ions are highly toxic, and wastewater treatment is difficult. Few factories use this process for large-scale production.

Electrolytic copper foil: Let's talk about the production methods of copper foil
Electrolytic copper foil: Let's talk about the production methods of copper foil. Copper foil is a negative electrode electrolytic material, which is a thin and continuous metal foil deposited on the substrate layer of the circuit board. According to different methods, copper foil can be divided into many types. Copper foil can be divided into: thick copper foil (>70m), conventional copper foil (>18m but <70m), thin copper foil (>12m but <18m), ultra-thin copper foil (<12m), etc.

Let me explain the reasons for the rough surface of electrolytic copper foil.
Let me explain the reasons for the rough surface of electrolytic copper foil. Impurities are difficult to precipitate out of water and easily enter the electrolyte. If fiberglass is attached to the surface of the pure water tank, it must first be scrubbed with weak acid water, and after the fiberglass is completely cured and dried, it should be scrubbed with weak alkali water. After the soluble high polymers in FRP are completely removed, use recycled water for production; otherwise, the electrolytic copper foil will be very rough.

Let me explain the characteristics of electrolytic copper foil and rolled copper foil.
Let me explain the characteristics of electrolytic copper foil and rolled copper foil. Lithium copper foil generally has a thickness of less than 20m and is an important raw material for making lithium batteries. It is widely used in automotive power lithium batteries, 3C digital products, energy storage, and other fields. Standard copper foil is commonly used in the electronics industry such as printed circuit boards (PCBs).

What are the uses of electronic copper foil?
Both sides of the electronic copper foil shall be free of scratches, pits, wrinkles, dust, oil stains, corrosion, fingerprints, pinholes, and penetration points, as well as other defects that may affect the service life, usability, or appearance of the copper foil.
