INSULATION SHEET, INSULATION SHEET WITH BASE MATERIAL, AND MULTILAYER PRINTED CIRCUIT BOARD

摘要

PROBLEM TO BE SOLVED: To provide an insulation sheet, an insulation sheet with a base material and a multilayer printed circuit board using the insulation sheet capable of forming a conductive circuit with excellent smoothness and adhesiveness to an insulation resin layer. SOLUTION: The insulation sheet is formed of a resin composition containing hardening resin and an inorganic filling material and has a first exothermic peak and a second exothermic peak located at a higher temperature than the first peak. The multilayer printed circuit board uses the insulation sheet. COPYRIGHT: (C)2006,JPO&NCIPI
