Description
上記の有機樹脂層はエチレン系共重合体、低融点オレフィンポリオレフィン系樹脂及び相溶化剤を含み、エチレン系共重合体に低融点オレフィンポリオレフィン系樹脂を添加し、エチレンチェーンとオレフィンチェーンとの相分離を誘導した後、相溶化剤を添加することにより製造される。
エチレンとビニルアセテートの共重合体100重量部、低融点プロピレン樹脂5重量部、及び相溶化剤5重量部を含有する有機樹脂層に酸化防止剤を配合した後、原料をシリンダー温度200乃至220℃、ダイ温度180乃至200℃で維持されている押出機に投入した後、低速で始め徐々に高速で押出した。原料がダイを通じて出始めると、吐出量800乃至1200g/minになるよう数分間速度を調整した後、厚さが30μm前後になるようブロー押出し、ウレタン系接着剤を用いて厚さ130μmの純アルミニウム板の一面とラミネートして穿孔加工用シートを作製した。
エチレン系共重合体、低融点プロピレン系樹脂、及び相溶化剤の具体的な成分及び組成比を除外して、実施例1に記載された方法に従って穿孔加工用シートを作製した。エチレン系共重合体、低融点プロピレン系樹脂、及び相溶化剤の具体的な成分及び組成比は下記の表1に示すとおりである。
エチレンとビニルアセテートの共重合体100重量部、PEワックス樹脂5重量部、及び相溶化剤5重量部を含有する有機樹脂層に酸化防止剤を配合した後、原料をシリンダーの温度200乃至220℃、ダイの温度180乃至200℃で維持されている押出機に投入した後、低速で始め徐々に高速で押出した。原料がダイを通じて出始めると、吐出量800乃至1200g/minになるよう数分間速度を調整した後、厚さが30μm前後になるようブロー押出し、ウレタン系接着剤を用いて厚さ130μmの純アルミニウム板の一面とラミネートして穿孔加工用シートを作製した。
エチレン系共重合体、PEワックス樹脂及び相溶化剤の具体的な成分及び組成比を除外して、実施例19に記載された方法に従って穿孔加工用シートを作製した。エチレン系共重合体、PEワックス樹脂及び相溶化剤の具体的な成分及び組成比は、下記の表1に示すとおりである。
エチレンとビニルアセテート共重合体100重量部だけを含み、低融点プロピレン系樹脂、PEワックス樹脂及び相溶化剤を含まない有機樹脂層に酸化防止剤を配合した後、原料をシリンダー温度200乃至220℃、ダイ温度180乃至200℃で維持されている押出機に投入した後、低速で始め徐々に高速で押出した。原料がダイを通じて出始めると、吐出量800乃至1200g/minになるよう数分間速度を調整した後、厚さが35μmになるようブロー押出し、ウレタン系接着剤を用いて厚さ130μmの純アルミニウム板の一面とラミネートして穿孔加工用シートを作製した。
エチレン系共重合体の具体的な成分、及びエチレン系共重合体及び相溶化剤の具体的な組成比を除外し、比較例1に記載された方法に従って、穿孔加工用シートを作製した。エチレン系共重合体の具体的な成分及び、エチレン系の共重合体及び相溶化剤の具体的な組成比は下記の表1に示すとおりである。
上記の実施例1乃至36及び比較例1乃至12に従って作製された穿孔加工用シートに対し、ドリル加工を実施して穴位置の精密度、内壁の粗度及び穴の内のスミアの発生を評価した。
ドリル加工の方法は、実施例1乃至36及び比較例1乃至12に従って作製された穿孔加工用シートを、有機樹脂層にラミネートされた面がドリルに接する方に置き、その下に厚さ0.4mmの両面銅箔印刷回路基板(FR-4製品、銅箔厚さ18μm)を7枚重畳し、さらにその下に厚さ1.5mmのベークライト(bakelite)板で構成されるバックアップボードを配置し、印刷回路基板の穿孔加工を実施した。
ドリルビート:直径0.25mm
回転数:125,000rpm
移送速度:2.5m/min
隣接加工穴の中心間の距離:0.5mm
ドリルビート数:5,000ヒット
以上の結果を表1に示した。
これに比べ、ミクロ相分離を誘導するポリオレフィン系樹脂を含有しない有機樹脂層の場合、穴の位置の精密度が落ち、内壁の粗度が悪く、穴のスミア発生が増加した。
