    摘要: A printed circuit board for high speed processing devices such as RAMBUS is disclosed. Adhesive means are interposed between a plurality of both-face copper clad laminates, and each of the adhesive means consists of a clad laminate and prepreg layers formed on both faces of the clad laminate. The sum total of the thicknesses of the clad laminates and the prepreg layers is smaller than that of the conventional printed circuit board. Therefore, when carrying out a pressing to attach the copper foils, the thickness deviations are decreased compared with the conventional case, and therefore, the occurrence of impedance defects can be prevented.
