Description
図1〜図3は、本発明の第1の実施の形態に係る固体電解コンデンサの製造方法を説明するための図である。まず、図1(a)に示すように、陽極箔10および陰極箔20を準備する。陽極箔10は、表面に誘電体酸化皮膜(図示せず)が形成された弁金属からなる。陽極箔10に用いられる弁金属としては、アルミニウム等の金属があげられる。誘電体酸化皮膜は、弁金属の表面にエッチング処理および化成酸化処理を施すことによって形成することができる。陰極箔20は、表面に炭化物粒子(図示せず)が保持されたアルミニウム等の金属箔からなる。陽極箔10および陰極箔20は、略同一寸法を有する。
実施例1においては、図4(a)の固体電解コンデンサ300を作製した。まず、陽極箔10として、エッチング処理および化成処理が施されたアルミニウム化成箔を2.7mm幅に裁断したものを用いた。陰極箔20として、陽極箔10と同一幅を有し、表面に炭化物粒子が保持されたアルミニウム箔を用いた。この陽極箔10と陰極箔20とを、セパレータ30を介して巻回して巻回素子100を作成した。
実施例2においては、実施例1で作製した固体電解コンデンサ300の封口部材40側に座板80を密着させ、陽極端子11および陰極端子21に座板80を貫通させ、陽極端子11および陰極端子21を座板80の貫通孔の根元から互い方向に90度折り曲げ、座板80からはみ出る陽極端子11および陰極端子21を切断した。それにより、図4(b)に示す表面実装型の固体電解コンデンサ300aを作製した。
比較例1においては、実施例1と同様の固体電解コンデンサを作製した。ただし、酵素を用いた天然繊維の分解・除去工程を省略した。
比較例2においては、実施例2と同様の固体電解コンデンサを作製した。ただし、酵素を用いた天然繊維の分解・除去工程を省略した。
実施例1,2および比較例1,2に係る固体電解コンデンサの初期電気的特性を調べた。各値を表1に示す。実施例1,2および比較例1,2に係る固体電解コンデンサはそれぞれ30個ずつ作製されており、表1の各値はそれらの平均値を示している。
次に、実施例2および比較例2に係る固体電解コンデンサのリフロー後の電気的特性および外観を調べた。リフローにおいては、熱風式リフロー炉を用いた。180℃〜200℃の温度範囲を120秒、200℃以上の温度範囲を120秒とし、260℃を上限温度とする温度プロファイルとした。各固体電解コンデンサに対して、上記リフローを2回施した。各電気的特性値を表2に示す。表2においても、各値は30個のサンプルの平均値を示している。また、表3に外観異常の有無を示す。表3においては、30個のサンプルのうち異常が認められたサンプルの数が分数で示されている。
