Surface Treatment Machine with maxmum winding diameter 800mm for
PCB copper foil equipment
The purpose of surface treatment for electrolytic copper foil is to
enhance its quality, performance, and stability, making it suitable
for high-demand applications in electronics, electrical
engineering, communications, and other fields. This treatment
process involves removing impurities and oxides, improving adhesion
and coating properties, enhancing corrosion and wear resistance,
optimizing electrical conductivity and welding performance, and
increasing surface wetting and adhesion. These enhancements enable
electrolytic copper foil to meet the stringent requirements of
various industrial and technological sectors, leading to the
production of high-quality, high-performance copper foil products.
Optimizing and controlling these treatment processes is essential
for ensuring the reliability and stability of copper foil in
complex environments, while also meeting the specific demands of
different industries.
The above specifications detail the various stages of the copper
foil surface treatment process, including unwinding, pickling,
coarsening, solidifying, washing, blackening, galvanizing,
passivating, silane treatment, drying, and rolling up. The
equipment is capable of handling copper foils with a thickness
range of 9 to 105 micrometers and a maximum width of 1380mm, which
can be customized according to specific customer requirements. The
equipment is designed to control tension accurately and has a
maximum speed of 45 meters per minute. The water consumption is
approximately 28.8 cubic meters per hour, facilitated by 5 large
washing tanks and 16 small washing tanks. The total electrical load
of the equipment is approximately 250KW, excluding the rectifier
power supply.
