Description
2,6−ジアミノ−2,5,6−トリメチルヘプタン−3−オール アミンフラックス剤が以下の手順を使用して製造された。最初に、2,5,6−トリメチル−2,6−ジニトロヘプタン−3−オール中間体が以下の合成方法を使用して製造された。
2,6−ジアミノ−2,6−ジメチル−5−フェニルヘプタン−3−オール アミンフラックス剤が以下の手順を使用して製造された。最初に、2,6−ジメチル−2,6−ジニトロ−5−フェニルヘプタン−3−オール中間体が以下の合成方法を使用して製造された。
下記式
下記式
実施例3〜4のそれぞれに従って製造されたアミンフラックス剤が個別に、エピクロロヒドリンとビスフェノールAとの液体エポキシ樹脂反応生成物(ザダウケミカルカンパニーからD.E.R.商標331商標として入手可能)と1:3重量比で混合されて、それぞれ実施例5および6の硬化性アミンフラックス組成物を形成した。
実施例5〜6に従って製造された硬化性アミンフラックス組成物のフラックス能力が、以下の手順を用いて評価された。各評価において、はんだ付けされる電気接点として銅クーポンが使用された。この銅クーポンのそれぞれについてはんだ付けされる表面は(1)まず、微細紙やすり(600グリット)で研磨し、(2)次いで、5%過硫酸NH4溶液でクリーニングし、(3)次いで脱イオン水ですすぎ、(4)次いで、30秒間1%ベンゾトリアゾール溶液中に浸漬し、並びに(5)次いで、窒素でブロー乾燥させることによって前処理された。銅クーポンの前処理の後で、それぞれ1種類の硬化性アミンフラックス組成物の小滴が個々に、1枚の銅クーポンのはんだ付けされる表面上に分配された。鉛を含まないはんだ(95.5重量%Sn/4.0重量%Ag/0.5重量%Cu)の直径0.381mmのボール4つが、各銅クーポン上のフラックス組成物の液滴中に配置された。使用されたこの鉛を含まないはんだの溶融範囲は217〜221℃である。次いで、この銅クーポンは、145℃に予備加熱されたホットプレート上に置かれ、そこで2分間保持された。次いで、この銅クーポンは260℃に予備加熱された別のホットプレート上に配置され、そこではんだがリフロー条件(存在するフラックス組成物に応じて45秒〜3分)に到達するまで保持した。次いで、この銅クーポンは加熱から取り外され、(a)元々配置された4つのはんだボールの融合および合体の程度、(b)フローおよび広がりを評価するための得られた合体したはんだのサイズ、並びに(c)銅クーポンの表面へのはんだの結合によって評価された。これらフラックス組成物およびヒドロキシステアリン酸参照材料のフラックス能力を説明するために、以下のような0〜4の等級が使用された:
1、2=はんだ滴どうしの部分的〜完全な融合、しかしはんだは銅クーポンと結合せず;
3=はんだ滴どうしの完全な融合、しかし最小限のはんだの広がりおよびフロー;
4=はんだ滴どうしの完全な融合、銅クーポンの表面上での良好なはんだの広がりおよびフロー、並びに銅クーポンへのはんだの結合。
