Description
本発明に係る配線基板の製造方法の第一実施形態を図1,2,3A~3N,4A,4B,5A~5Dに基づいて説明する。
本発明に係る配線基板の製造方法の第二実施形態を図6,7A~7Dに基づいて説明する。ただし、前述した実施形態と同様な部分については、前述した実施形態の説明で用いた符号と同様な符号を用いることにより、前述した実施形態での説明と重複する説明を省略することとする。
本発明に係る配線基板の製造方法の第三実施形態を図8,9A~9Eに基づいて説明する。ただし、前述した実施形態と同様な部分については、前述した実施形態の説明で用いた符号と同様な符号を用いることにより、前述した実施形態での説明と重複する説明を省略することとする。
なお、上述した第三実施形態において、アンダーフィル除去冶具Tとして硬度が比較的大きい材質を適用することも可能である。具体的には、例えば、Cu、Ti、Sn、Fe、Al、Cr、Ag、Au、Pt、Ni、Mnのいずれか、または2種以上の合金、もしくは2種以上の複合体等を適用することが可能である。このような硬度が比較的大きい材質をアンダーフィル除去冶具Tに適用すると、アンダーフィル2Cを除去する際のアンダーフィル除去冶具Tの変形を抑えることができ、アンダーフィル2Cを除去する位置の精度を高めることが可能となる。
また、上述した第三実施形態において、アンダーフィル除去冶具Tとして、吸引機構に接続されたシリンジニードルを適用して、インターポーザ3の側面の外周縁に付着したアンダーフィル2Cを吸い取りながら除去するようにすることも可能である。このような吸引機構に接続されたシリンジニードルをアンダーフィル除去冶具Tとして適用すると、アンダーフィル2Cが除去中にアンダーフィル除去冶具T上で拡がって、インターポーザ3へ再付着してしまうことを防ぐことができると共に、除去したアンダーフィル2がFC-BGA用配線基板1上の幅方向へ拡がってしまうことを防ぐことができる。
また、上述した第三実施形態において、樹脂供給工程前に、マスキングを形成する工程を行って、樹脂除去工程を行ってから、樹脂硬化工程を行う前に、マスキングを除去する工程を行うようにすることも可能である。
