摘要 |
PROBLEM TO BE SOLVED: To inhibit the generation of voids and scale wrinkles on the surface through satisfactory simultaneous hardening at the time of lamination and hardening of an interlayer insulating bonding agent applied on a copper foil and an undercoat agent applied on an internal layer circuit board. SOLUTION: In this manufacturing method, the internal layer circuit board is provided with a thermosetting type or light/thermosetting undercoat agent 3 and a copper foil 5 having the thermosetting type interlayer insulating bonding layer 4 is laminated on the undercoat layer. In this case, the undercoat agent 3 and interlayer insulating bonding agent are mainly composed of epoxy resin and includes the hardening agent of the same kind. |
