There are many processes for the copper clad laminate board sheet of Chinalco, the first is explosive copper clad laminate board sheet , most of which are thick; the second is rolling plate, the proportion of which is still relatively high, generally more than 10%; the third is adhesive copper clad laminate board sheet , which is very thin, usually more than 10micrcon.
 
The production process of copper clad laminate board sheet coil is to melt the aluminum ingot into aluminum liquid completely, put it in a static furnace, degassing and filtering online, and then flow into the composite area. The copper plate and strip directly enter the composite area and contact with the aluminum liquid surface, and continuously roll out the copper clad laminate board sheet and strip. To solve the problems of high production cost, large energy consumption, complex process, high labor intensity and environmental pollution in the existing production methods of aluminum copper composite metal plate and strip, so as to reduce production cost, improve production efficiency, avoid environmental pollution and improve product quality, with the characteristics of energy saving, advanced technology and high yield.


 
Copper clad laminate board sheet coil, another common process, is to stick the copper foil on the surface of the alumina roll through high-temperature insulation adhesive, which can not only keep the insulation between copper and aluminum, but also firmly stick the copper and aluminum together, which can ensure that the high temperature of 200 ℃ in 2 minutes does not melt and does not crack.

Common specifications of Copper clad laminate board sheet coil:
Thickness: 0.4mm, 0.6mm, 0.8mm, 1.0mm
Thickness of copper layer: 15micron, 20micron, 25micron, 35micron, 150micron
