1.熱安定性とは、銅箔の焼きなまし前後の引張強度の偏移比で、EAとEH3との引張強度の差の絶対値を、EAで割って計算されたものである。その値が小さければ小さいほど熱安定性が良い。
2.MIT−Nf(ASTM−D2176)のテスト条件は、R=0.8mm、荷重500gである。
3.IPC−Df(IPC−TM−650)は、直径0.92mmのマンドレル(mandrel)で試験したデータから数値分析で計算されたものである。
4.EAは、焼きなましをしていない状態を示し、EF3は、180℃で60分焼きなました状態を示している。
5.EDは電解銅箔、RAは圧延銅箔、Pは圧延銅箔の圧延方向に沿って試験したデータをそれぞれ示している。
6.厚さは、IPC−4562の規定に基づく面積重量法により測定した。
7.引張強度、サンプルサイズの測定および測定条件は、IPC−4562にしたがった。
8.SHTEは、超高温伸長(Super High Temperature Elongation)であることを示している。
