Abstract
Au及びPdから選択された1種又は2種の元素の含有量の合計が0.5質量%以上1.0質量%以下であり、Caの含有量が50質量ppm以上100質量ppm以下である、残部がAgからなるものとする。
Description
(1)光反射率
同種のLEDに実施例1〜12、比較例1〜8及び純銀のボンディングワイヤを結線し、樹脂封止をして各実施例、比較例及び純銀のボンディングワイヤによって結線したLED素子を作製した。作製した素子をJIS C8152に規定の方法により全光束測定を行った。測定結果は、純銀のワイヤで結線したLEDの光量を100%としたときの各実施例、比較例の光量を指数に換算して示した。
(2)伸線加工時の断線回数(伸線加工性)
実施例1〜12及び比較例1〜8のボンディングワイヤについて、1kgのワイヤを直径50μmから直径20μmまで伸線した時に発生した断線回数をカウントした。
(3)FAB形成性
実施例1〜12及び比較例1〜8のボンディングワイヤに対して、ワイヤボンダー(K&S社製、IConn)にてワイヤ直径の2.0倍の大きさのFABを窒素ガス雰囲気で作製した。FAB形成性の評価としては、実施例1〜12及び比較例1〜8のボンディングワイヤ毎にFABを500個ずつ作製した後、汎用型電子顕微鏡(日本電子(株)製、JSM−6510LA)にて外観観察を行い、作製したFABのワイヤ平行方向と垂直方向の長さをそれぞれ測定した。FABのワイヤ平行方向の長さXと垂直方向の長さYの比(X/Y)を真球性の指標として、95%〜100%であれば「真球性有り」と判断し、真球性有りと判断したFABの個数をカウントした。結果は、作製した500個のFABに対する真球性有りと判断したFABの個数の比率を示す。
(4)HAZ長さ
上記(3)においてFABを作製したワイヤを上記汎用型電子顕微鏡にて外観観察を行い、FAB直近のワイヤ部分に発生したHAZの長さを測定し、その平均値を算出した。
(5)偏芯発生率
上記(3)においてFAB1を作製したワイヤWを上記汎用型電子顕微鏡にて外観観察を行い、FAB1の重心位置CからワイヤWの中心軸Lまでのワイヤ垂直方向(ワイヤの短手方向)Pに沿った距離Dを計測した(図2参照)。計測した距離Dがワイヤ直径φwの0.1倍以上離れていたワイヤWを偏芯があると判断した。偏芯発生率は、作製した500個のFAB1に対する偏芯が発生した個数の比率を示す。
