CCL (Copper Clad Laminate) is the substrate material used in the production of PCB (Printed Circuit Board) and serves as the basic structure of electronic products. With the increasing demand for electronic products, large production and sales of CCL and PCB promote the improvement of process and automatic level in CCL production. Automatic layer stacking machines act as special logistics conveyor systems according to CCL production requirements.
Copper clad laminate manufacturing process
The CCL manufacturing process is shown in the Figure, mixed resin is synthesized by resin, solvents and other additives in mixing machine, transferred to gluing unit, drying, and then prepreg is prepared. Prepreg is cut firstly by a cutting machine, then different models of prepreg are arranged in the layer distributor. Prepreg, copper foil and steel plate are stacked up, and layups made by hot pressing is called CCL, and packaged after testing. Steel plate separated from CCL in CCL break-down system, and can be recycled after cleaning and drying.

The layer stacking machine is the main equipment of CCL production, and consists of a CCL lay-up system, CCL break-down system and steel plate cleanser. The functions of the CCL return line include a stack up of the multilayers, breakdown of the CCL and steel plate, and cleaning of steel plate to realize recycling. The CCL return line is a special material conveyor line for CCL production, which can meet the process requirement.
The CCL return line is based on PLC control of servo control technology and can realize program control by sensor technology, including stack-up line and break-down line, motor speed, position detection and positioning, etc.
