Реферат: A PROCESS FOR PRODUCING AN ELECTRODEPOSITED COPPER FOIL WITH ITS SURFACE PREPARED, COMPRISING THE STEPS OF : SUBJECTING AN ELECTRODEPOSITED COPPER FOIL HAVING A SHINY SIDE AND A MATTE SIDE WHOSE AVERAGE SURFACE ROUGHNESS (Rz) IS IN THE RANGE OF 2.5 TO 10 ?m TO AT LEAST ONE MECHANICAL POLISHING SO THAT THE AVERAGE SURFACE ROUGHNESS (Rz) OF THE MATTE SIDE BECOMES IN THE RANGE OF 1.5 TO 3.0 ?m ; AND SUBJECTING THE MATTE SIDE HAVING UNDERGONE THE MECHANICAL POLISHING TO A SELECTIVE CHEMICAL POLISHING SO THAT THE AVERAGE SURFACE ROUGHNESS (Rz) OF THE MATTE SIDE BECOMES IN THE RANGE OF 0.8 TO 2.5 ?m. THE INVENTION FURTHER PROVIDES AN ELECTRODEPOSITED COPPER FOIL WITH ITS SURFACE PREPARED, PRODUCED BY THE ABOVE PROCESS, AND STILL FURTHER PROVIDES PWBs AND A MULTILAYER LAMINATE OF PWBs, PRODUCED WITH THE USE OF THE ABOVE ELECTRODEPOSITED COPPER FOIL WITH ITS SURFACE PREPARED. THE MECHANICALPOLISHING FOLLOWED BY CHEMICAL POLISHING OF THE MATTE SIDE ENABLES OBTAINING AN ELECTRODEPOSITED COPPER FOIL WITH ITS SURFACE PREPARED, THE MATTE SIDE OF WHICH EXHIBITS EXCELLENT PROPERTIES, AND HENCE ENABLES OBTAINING PWBs AND A MULTILAYER PWBs WHICH HAVE EXCELLENT PROPERTIES.(FIGURE 6)
