摘要: PROBLEM TO BE SOLVED: To provide a multilayer wiring board, having not only rigidity but also superior heat dissipation characteristic and noise characteristic. SOLUTION: The method for manufacturing board comprises step forming resist metal layer pattern, using plate as lead electrolytic plating; removing the by etching, frame 116 on outermost of 113 partially etching 101b which is used at formation side 113, mounting semiconductor chip 202.
