固形分濃度15wt%のポリアミド酸溶液(P1)200重量部と、板状フィラーとして窒化ホウ素(昭和電工(株)社製、商品名:UHP-1、鱗片形状、平均長径8μm、)を分級機により25μm以上の粒子を取除いたもの15重量部と、球状フィラーとしてアルミナ(住友化学(株)社製、商品名:AA-3、球状、平均粒子径3μm)15重量部とを均一になるまで遠心攪拌機で混合し、熱伝導性フィラーを含有するポリアミド酸溶液を得た。このポリアミド酸の溶液を硬化後の厚みが25μmとなるように塗布し、130℃で加熱乾燥し溶剤を除去した。その後、130~360℃の温度範囲で、段階的に30分かけて昇温加熱して、厚さ12μmの電解銅箔上にポリイミド樹脂中に熱伝導性フィラーが分散した絶縁層を形成し、高熱伝導性金属張積層体を作製した。この絶縁層における窒化ホウ素及びアルミナの含有量は各25wt%である。すなわち、絶縁層中における熱伝導性フィラーの合計の重量分率は50wt%である。また、熱伝導性フィラーを含有するポリアミド酸溶液には、25μm以上の熱伝導性フィラーは含有されていなかった。
実施例1で用いたと同じ銅箔上にフィラーを配合していないポリアミド酸溶液(P2)を硬化後の厚みが2μmとなるように塗布し、130℃で加熱乾燥し溶剤を除去した。次に、その上に実施例1と同様に板状フィラーと球状フィラーを混合した熱伝導性フィラーを含有するポリアミド酸の溶液を硬化後の厚みが21μmとなるように塗布し、130℃で加熱乾燥し溶剤を除去した。さらに、その上にフィラーを配合していないポリアミド酸溶液(P2)を硬化後の厚みが2μmとなるように塗布し、130℃で加熱乾燥し溶剤を除去し、その後、130~360℃の温度範囲で、段階的に30分かけて昇温加熱して、銅箔上に3層のポリイミド層からなる絶縁層を有するフレキシブル基板用積層体を作製した。絶縁層の構成を表1に、フィルム(F2)の評価結果を表2に、高熱伝導性金属張積層体の特性評価結果を表3に示す。
板状フィラーとして分級機により30μm以上の粒子を取除いた窒化ホウ素(電気化学工業(株)社製、商品名:HGPE、鱗片形状、平均長径4.5μm)15重量部を使用した以外は実施例1と同様に行った。
板状フィラーとして分級機により10μm以上の粒子を取除いた窒化ホウ素(電気化学工業(株)社製、商品名:HGP7、鱗片形状、平均長径2.5μm)15重量部を使用した以外は実施例1と同様に行った。
板状フィラーを使用せず、球状フィラーとしてアルミナ(住友化学(株)社製、商品名:AA-3、球状、平均粒子径3μm)30重量部を用いた以外は実施例1と同様に行った。
板状フィラーとして窒化ホウ素(昭和電工(株)社製、商品名:UHP-1、鱗片形状、平均長径8μm)30重量部を使用し、球状フィラーを用いていない以外は実施例1と同様に行った。
板状フィラーとして窒化ホウ素(昭和電工(株)社製、商品名:UHP-1、鱗片形状、平均長径8μm)の分級をせず通常市販されている状態で15重量部を使用した以外は実施例2と同様行った。この窒化ホウ素には、32μm以上の粒子が2wt%存在している。
