Copper clad laminate (CCL) consists of an inner layer of prepreg laminated on both sides with a thin layer of copper foil. Lamination is achieved by pressing together one or more plies of copper and prepreg under intense heat, pressure and vacuum conditions.

Prepreg is an industry term derived from the contraction of ‘‘previously impregnated’’. Prepreg is a dielectric material that provides electrical insulation and other properties. Prepreg is manufactured by the impregnation of fiberglass fabric with specially formulated resins. The resin confers specific electrical, thermal and physical properties to the prepreg and is critical to the proper functioning of a PCB. Prepreg may be incorporated into a CCL or sold as a separate product.

PCB fabricators use prepreg and CCL to construct multilayered PCBs in a complex process comprised of multiple operations that are ...
