Description
図1は、コンデンサ素子を示す模式図であり、(a)は平面図、(b)は断面図である。図1に示すコンデンサ素子10は、100〜500μm程度の厚みを有する略正方形の板であり、正方形板の各辺に沿って陽極部の陽極引出部13を有し、中心部に陰極部の陰極引出部14を有する。陽極引出部13と陰極引出部14とは、分離層15で区分されている。陽極引出部13の表面には、多数のバンプ電極16が立設されている。
図2は、端子板を示す模式図であり、(a)は平面図、(b)は断面図である。図2に示す端子板20は、プリント基板に接続される端子部分であり、コンデンサ素子10とほぼ合致する搭載ランドを有する。すなわち、端子板20には、中心に陰極電極板21が設けられ、その陰極電極板21の四方を囲むように陽極電極板22が設けられている。四方の陽極電極板22と陰極電極板21との間は、絶縁性樹脂23によって絶縁されている。
図3は、コンデンサ素子10と端子板20との実装関係を示す図である。図3に示すように、固体電解コンデンサは、陽極引出部13及び陰極引出部14が形成されている面を向けて、コンデンサ素子10を端子板20に重ね合わせることにより構成される。この固体電解コンデンサにおいて、陽極引出部13は、バンプ電極16などの電極引出部による実装であり、陰極引出部14に関しては導電性接着剤を介した実装である。
このように、固体電解コンデンサは、まず、端子板20の搭載面上の周縁全体に封止樹脂30を塗布しておく。そして、封止樹脂30の塗布の後、コンデンサ素子10と端子板20とを重ね合わせる。そのため、コンデンサ素子10と端子板20との隙間から封止樹脂を充填する必要はなく、固体電解コンデンサを封止樹脂30によって封止する工程は極めて簡便なものとなる。また、確実に絶縁を要する箇所を封止樹脂30で確実に覆って絶縁することができる。
