Description
第2主面側において露出状態にある最外層の樹脂絶縁層の外側主面を基準面とした場合、その外側主面から端子内面の端部までの長さは、外側主面から端子内面の中央部までの長さよりも短くなっていてもよい。また、当該外側主面を基準面とした場合における外側主面から端子内面までの長さは、端子内面の中央部から端部に行くに従って徐々に短くなっていてもよい。これらの構造であると、端子内面の端部での応力集中が回避される。このため、樹脂絶縁層にクラックが発生するリスクが減り、従来に比べて多層配線基板の信頼性が向上する。
また、第2主面側接続端子は、母基板が接続される主面側に設けられてもよいし、その主面の反対側、例えばICチップが搭載される主面側に設けられてもよい。
以下、本発明を多層配線基板に具体化した第1の実施の形態を図面に基づき詳細に説明する。図1は、本実施の形態の多層配線基板の概略構成を示す拡大断面図である。また、図2は、上面側から見た多層配線基板の平面図であり、図3は、下面側から見た多層配線基板の平面図である。
