METAL-FOIL-ATTACHED ADHESIVE SHEET, METAL-FOIL-ATTACHED LAMINATED BOARD, METAL-FOIL-ATTACHED MULTI-LAYER BOARD, AND METHOD OF MANUFACTURING CIRCUIT BOARD

摘要

A metal-foil-attached adhesive sheet comprises: a metal foil, an exfoliation layer prepared on the metal foil, and an adhesive layer formed with a thermosetting resin composition in a semi hardening state. When a filling strength in an interface between the metal foil and the exfoliation layer is P1, and a filling strength in an interface between the exfoliation layer and the hardened adhesion layer is P2; P1 is greater than P2 (P1P2).;COPYRIGHT KIPO 2016
