なお、各例で得られた銅張積層板は、以下の方法で性能を測定及び評価した。
銅張積層板を銅エッチング液に浸漬することにより銅箔を取り除いた幅4mm×長さ30mm×厚さ0.4mmの評価基板を作製し、動的粘弾性測定装置(株式会社ユービーエム製、商品名:DVE-V4)を用いてガラス転移温度を測定した。上記で作製された評価基板を検出器に取り付け、昇温速度5℃/分、周波数10Hz、測定温度範囲40~360℃の測定条件にて測定し、損失弾性率が最大になる温度をガラス転移温度とした。ガラス転移温度が高いほど、耐熱性に優れることを示す。なお、損失弾性率が360℃を超えた場合は「>360」として表1に記載した。
銅張積層板を25mm角の大きさに切り出した評価基板を作製し、該評価基板を温度288℃のはんだ浴に、最大で90分間フロートしながら、外観を観察することにより、膨れが発生するまでの時間を測定した。評価結果は、90分間フロートした時点で膨れが確認されなかったものを「A」として表1に記載した。
銅張積層板を銅エッチング液に浸漬することにより銅箔を取り除いた5mm×5mm角の評価基板を作製し、TMA試験装置(ティー・エイ・インスツルメント・ジャパン株式会社製、TMAQ400EM)を用いて圧縮法で熱機械分析を行った。評価基板を上記装置に装着後、昇温速度10℃/分で260℃まで昇温し、降温速度10℃/分で10℃まで降温した後、再度、昇温速度10℃/分で320℃まで昇温した。1回目の昇温時と2回目の昇温時の合計2回、熱膨張率を測定した。2回目の測定における30℃から100℃までの平均熱膨張率を算出し、これを熱膨張率の値とした。
銅張積層板を銅エッチング液に浸漬することにより銅箔を取り除いた40mm×40mmの評価基板を、膨潤液である「スエリングディップ・セキュリガントP」(グリコールエーテル類、水酸化ナトリウムの水溶液、アトテックジャパン株式会社製)に60℃で10分間浸漬し、次に粗化液である「コンセントレート・コンパクトP」(KMnO4:60g/L、NaOH:40g/Lの水溶液、アトテックジャパン株式会社製)に80℃で20分間浸漬し、最後に中和液である「リダクションショリューシン・セキュリガントP」(硫酸の水溶液、アトテックジャパン株式会社製)に40℃で5分間浸漬し、その後、80℃で10分間乾燥することで、デスミア処理を行った。
デスミア処理前の乾燥重量に対するデスミア処理後の重量減少量(g/m2)を算出し、これを耐デスミア性の指標とした。デスミア処理後の重量減少量が小さい程、耐デスミア性に優れる。
銅張積層板を銅エッチング液に浸漬することにより銅箔を取り除いた幅10mm×長さ100mm×厚さ0.4mmの評価基板を作製した。該評価基板の最表面の絶縁層の一端を、該絶縁層が積層されている絶縁層との界面で剥がして、剥がした部分をつかみ具でつかみ、引張り試験機を用いて垂直方向に引き剥がしたときの層間ピール強度を測定した。なお、引張り速度は約50mm/分、測定温度は室温とした。
銅張積層板を銅エッチング液に浸漬することにより、外層銅箔を3mm幅に形成した評価基板を作製した。該評価基板の一端を外層銅層と絶縁層との界面で剥がして、剥がした部分をつかみ具でつかみ、引張り試験機を用いて垂直方向に引き剥がしたときの銅箔ピール強度を測定した。なお、引張り速度は約50mm/分、測定温度は室温とした。

希釈溶媒としてメチルエチルケトンを使用し、表1に記載された配合組成で各成分を混合してから6時間撹拌し、固形分濃度(すなわち、有機溶媒を除く熱硬化性樹脂組成物の含有量)65質量%のワニスを調製した。
次に、得られたワニスを厚さ0.1mmのEガラスクロスに含浸塗工し、110℃で3分間加熱乾燥することにより、熱硬化性樹脂組成物の含有量が47~48質量%のプリプレグを得た。
このプリプレグを4枚重ね、12μmの電解銅箔を上下に配置し、圧力3.0MPa、昇温速度4.0℃/分で240℃まで昇温後、85分間保持し、放圧後、30分間冷却することによって銅張積層板を得た。得られた銅張積層板を用いて、上記測定及び評価を行った。結果を表1に示す。
