Heat-resistant film base-material-inserted B-staged resin composition sheet excellent in adhesion to resin, multilayer board using the sheet and manufacturing process of the multilayer board

摘要

A heat-resistant film base-material-inserted B-staged resin composition sheet obtainable by adhering a layer of a B-staged resin composition to a heat-resistant film base material, wherein the heat-resistant film base material is plasma-treated before adhering the B-staged resin composition layer, a multilayer board using the above heat-resistant film base-material-inserted B-staged resin composition sheet in a buildup layer and/or a bonding layer, and a manufacturing process of the multilayer board.
