Description
図1に示したコンデンサ10と同様のコンデンサを、以下のようにして作製した。
上記実施例に係るコンデンサの参考のためにコンデンサを以下のようにして作製した。
まず、上記実施例で示したようにして、実施例と同様のコンデンサ素子を作製した。そして、基板厚み0.5mmで、銅箔厚36μmの銅配線パターンが、図8(a)(コンデンサ素子実装側)、図8(b)のように裏面に形成された、ガラスクロス含有耐熱性エポキシ樹脂からなるコンデンサ実装基板(7.3mm×4.3mmのサイズに対応)を下記の手法により準備した。
上記実施例に係るコンデンサとの比較のためにコンデンサを以下のようにして作製した。そして、図9に示すリードフレーム70に搭載した。コンデンサ素子の積層体を、リードフレーム70上の所定位置に搭載し、積層体の最下面に露出した導電体層(ペースト層)部分を、銀系の導電性接着剤を用いて、リードフレーム70の陰極リード部70bに接着し、表面が粗面化されていないアルミニウム箔の端部は、それぞれNEC製YAGレーザスポット溶接機で溶接して、リードフレーム70の陽極リード部70aと一体化した。
