Difference between CCL and PCB & Production Process of CCL PCB

CCL PCB refers to PCB made of CCL material. CCL is the raw material of PCB. CCL is also called laminate, substrate or copper-clad laminate. Copper Clad Laminate, referred to as CCL, is made of glass fiber cloth as reinforcement material, dipped in synthetic resin, single or double coated with copper foil, after heating and pressurizing a product. PCB factory is the downstream industry of CCL factory. CCL is etched through development to remove unwanted copper foil to form a circuit. If it is a multilayer PCB, it is necessary to laminate the CCL of a number of etched lines with adhesive sheets to form a multilayer board.

Copper Clad Laminate (CCL), as the substrate material in the manufacture of printed circuit board, mainly plays the role of interconnection, insulation and support for PCB, and has a great impact on the transmission speed, energy loss and characteristic impedance of signals in the circuit. Therefore, the performance, quality, manufacturability, manufacturing level, manufacturing cost and long-term reliability and stability of printed circuit board depend  largely on the copper clad plate.

CCL has to go through many processes (such as drilling, electroplating, wiring, welding prevention, etc.) before it becomes PCB. The process of PCB is very long. As for the processing technology can not be measured and explained by the same and different.

PCB and CCL both need to use hot and cold press, press copper foil and PP together to become CCL, and PCB is the inner line of CCL plus PP plus copper foil pressed together. Simply put, the circuit on the double-sided PCB is to design the copper on the CCL, through the circuit process (film – exposure – development – etching) to make.
