Abstract
【解決手段】 導電性粉末と、ガラス粉末と、有機ビヒクルとを含む導体ペーストであって、前記ガラス粉末が、酸化物換算で下記の組成からなる成分を含有し、下記式(1)を満たすことを特徴とする導体ペースト。
SiO 2 42.0〜65.0重量%、R 2 O(Rはアルカリ金属) 8.0〜18.0重量%、R’O(R’はアルカリ土類金属) 4.0〜20.0重量%、B 2 O 3 0〜18重量%、Al 2 O 3 3.0〜18.0重量%、La 2 O 3 0〜15重量%
(R2O+R’O+B2O3)/SiO2≦0.95 ・・・・・ (1)
【選択図】図1
Description
SiO 2 42.0〜65.0重量%、R 2 O(Rはアルカリ金属) 8.0〜18.0重量%、R’O(R’はアルカリ土類金属) 4.0〜20.0重量%、B 2 O 3 0〜18重量%、Al 2 O 3 3.0〜18.0重量%、La 2 O 3 0〜15重量%
(R 2 O+R’O+B 2 O 3 )/SiO 2 ≦0.95 ・・・・・ (1)
(R2O+R’O+B2O3)/SiO2≦0.95 ・・・・・ (1)
式(1)において (R2O+R’O+B2O3)/SiO2の値が0.95を上回ると、耐酸性及び耐水性が悪くなり、耐めっき液性と端子電極の緻密性の両立が困難になる。また、(R2O+R’O+B2O3)/SiO2は0.30以上であることが望ましい。これを下回ると流動性が悪くなる。
表1に示す酸化物組成になるようにガラス原料をそれぞれ調合し、白金ルツボを用いて約1300〜1450℃で溶融し、次いでグラファイト上に流出させて空冷して得られたガラスをスタンプミルで平均粒径35μm程度に粗粉砕後、アルミナボ−ルを用いたボールミルにより微粉砕し平均粒径が約4μmのガラス粉末A〜Mを得た。また平均粒径を約1.5μmとする以外は同様にしてガラス粉末Nを作製した。さらにまた、ガラス原料を約1150℃で溶融し、平均粒径を約1.5μmとする以外は同様にして、亜鉛系のガラス粉末Zを作製した。なお、表1中に*印がついているガラス粉末は、本発明の範囲外のものである。
次に、Cu粉末 100重量部とガラス粉末A 7重量部を、アクリル樹脂系バインダーをテルピネオールに溶解したビヒクル 40重量部と共にロールミルで混練して導体ペーストを作製し、これを試料1とした。
〔膜密度〕各コンデンサチップ(以下、単に「チップ」と言う)の端子電極付近断面を走査型電子顕微鏡で観察し、焼成膜中の気孔の状態を調べた。
〔素体への浸み込みの有無〕各チップの端子電極付近断面を走査型電子顕微鏡で観察し、ガラスの素体への浸み込みによって素体中に発生するマイクロクラックの有無を調べた。
〔耐熱衝撃性〕各チップ20個を350℃に設定した半田浴に10秒間浸漬した後、自然空冷し、各チップ中にクラックの発生した比率が0%の場合には○、10%以下の場合には△、10%より高い場合には×とした。
〔引っ張り強度〕対向する2つの端子電極に、リード線が電極表面に対して垂直になるようにそれぞれ半田付けし、強度測定器を用いてリード線を反対方向に引っ張り、電極部分や電極と素体との界面部分が破壊された時の値を調べた。
〔容量不良〕内部電極との接合性を見るために、各チップの静電容量を測定し、設計値の±10%以内のものを○、それ以上離れているものを×とした。
ガラス粉末Nを用いた以外は試料1と同様にして試料14−1を作製した。
