<p><P>PROBLEM TO BE SOLVED: To provide a resin-coated metal foil having excellent dielectric characteristics, excellent crack resistance, and excellent laser machining properties, and a printed circuit board. <P>SOLUTION: In the resin-coated metal foil, at least two resin layers, each of which is constituted of a resin composition containing a benzocyclobutene resin and a spherical inorganic filler are formed on at least one side a of metal foil. The multi-layer printed circuit board is obtained by a process in which the resin-coated foil is superposed on one side or both sides of an inner layer circuit board, and the obtained laminate is heated and pressed. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
