Description
(1)導電性金属箔(M1)上にベース層、中間メイン層、トップ層の少なくとも三層のポリイミド系樹脂層を有する片面導体積層体と導電性金属箔(M2)からなる基材を連続的に一対の加熱プレスロール間に導入し、上記トップ層に導電性金属箔(M2)を加熱圧着により積層一体化させる両面導体ポリイミド積層体の製造方法において、加熱プレスロール間に導入直前の片面導体積層体と導電性金属箔(M2)をそれぞれ200℃以上〜トップ層のポリイミド系樹脂のガラス転移点以下に予備加熱後に加熱プレスロール表面に接触させることを特徴とする両面導体ポリイミド積層体の連続製造方法である。
PMDA:無水ピロメリット酸
BTDA:3,3’,4,4’−ベンゾフェノンテトラカルボン酸無水物
DDE:4,4−ジアミノジフェニルエーテル
MABA:2’−メトキシ−4,4’−ジアミノベンズアニリド
ガラス製反応器に窒素を通じながらN,N−ジメチルアセトアミド2,532gを仕込み、続いて攪拌下に0.5モルのDDEと0.5モルのMABAとを仕込み、その後完全に溶解させた。この溶液を10℃に冷却し、反応液が30℃以下の温度に保たれるように1モルのPMDAを少量ずつ添加し、添加終了後引き続いて室温で2時間攪拌を行い、重合反応を完結させた。得られたポリイミド前駆体溶液はポリマー濃度15重量%及びB型粘度計による25℃でのみかけ粘度1000mPa・sであった。
ジアミン成分としてDDEの1モルを使用し、酸無水物成分としてBTDAの1モルを使用した以外は、合成例1と同様にしてポリイミド前駆体溶液を調整した。得られたポリイミド前駆体溶液はポリマー濃度15重量%及びB型粘度計による25℃でのみかけ粘度300mPa・sであった。
35μmロール状の電解銅箔(日鉱グールド社製)の粗化面にダイコーターを用いて合成例2で調整したポリイミド前駆体溶液2を12μmの厚みで均一に塗工した後、120℃の熱風乾燥炉で連続的に処理し溶剤を除去した。次にこのポリイミド前駆体層の上からリバース式ロールコーターを用いて合成例1で調整したポリイミド前駆体溶液1を200μmの厚みで均一に塗工し、120℃の熱風乾燥炉で連続的に処理し溶剤を除去した後、さらに合成例2で調整したポリイミド前駆体溶液2を15μmの厚みで均一に塗布し、次いで熱風乾燥炉で30分間かけて120℃から360℃まで昇温させて熱処理しイミド化させ、ポリイミド樹脂層の厚みが25μmで反りやカールのない平面性の良好な片面銅張品aを得た。この片面銅張品aの銅箔層とポリイミド樹脂層との間の180°引き剥がし強さ(JIS C−5016)を測定した結果は0.8kg/cmであり、エッチング後のフイルムの熱膨張係数は23.5×10-6(1/℃)であった。
製造例で調整した片面絶縁体層の銅張品の横幅500mmのロール巻きシートの樹脂面と同じ横幅寸法の35μmのロール巻きシートである圧延銅箔の粗化面とを、それぞれ窒素雰囲気下のガイドロールを経由して、一対の加熱プレスロール(外径は300mm、幅800mmで、表面付近には均一加熱手段としてナフタリンを封入したジャケット式のヒートパイプが埋め込まれ、内部の中心軸には誘電加熱コイルを内蔵させた構造)間に導入する前で加熱手段内蔵タイプのガイドロール3’(4’)にて予備加熱後に、加熱プレスロール表面温度360〜390℃、プレスロール間の線圧150〜170kg/cm、通過時間2〜5秒間の範囲内で加熱圧着した。このとき、同じ基材材料、同じ加熱プレスロール条件下での予備加熱しない場合と、予備加熱温度を150℃、250℃及び340℃に変更した場合について、得られた両面銅張品の表面状態を目視にて調査した結果を表1に示す。
上記の実施例1において、加熱プレスロール表面の設定温度360℃、プレスロール間の線圧150kg/cm、通過時間3秒間に設定し、且つ加熱プレスロール間へ導入される基材の予備加熱が無い場合と、予備加熱温度を250℃及び340℃とした場合のそれぞれについて、加熱プレスロールの表面粗さ(Ra)を0.01以下、0.05、0.20、10.0μmの4段間に変化させた場合に得られた両面銅張品の表面状態を目視にて調査した結果を表2に示す。
