MANUFACTURE OF COPPER CLAD LAMINATED BOARD

摘要

PURPOSE: To prevent rough pieces of a copper foil from being separated from copper foil and being embedded and left within a substrate when forming by using a thin copper foil. CONSTITUTION: Surface-coated zinc is surface-coated with cobalt and molybdenum compounds and copper foil having a surface roughness of Rmax. =2.0 to 7.5μm on the adhering surface is superimposed to a prepreg obtained by impregnating a base material with a thermosetting resin and drying and thereafter heated and pressured.
