Abstract
液晶ポリマーを絶縁体シートとして有する回路基板であって液晶ポリマーフィルムの脆化が抑制され耐久性に優れるものと、その様な回路基板を製造するための方法を提供する。
【解決手段】
本発明に係る回路基板の製造方法は、当該回路基板を構成する絶縁体シートのうち、少なくとも一方の表面シートとして液晶ポリマーフィルムを用い、当該液晶ポリマーフィルムを熱圧着するに当たり、離型材としてフッ素系多孔質フィルムを用いることを特徴とする。また、本発明の回路基板は、当該方法により製造されるものであって、耐久性に優れている。
【選択図】図1
Description
液晶ポリマーフィルムの両面銅張板(ジャパンゴアテックス社製、BIAC CC BC050F−B12B17、基材厚:50μm、銅箔厚:12μm、液晶ポリマー融点:310℃)の銅箔を両面エッチングし、ライン/スペースが100/100μmの直線回路パターンを形成した。別途、液晶ポリマーフィルム(ジャパンゴアテックス社製、BIAC BC050F、厚さ:50μm)の片面に、低圧水銀灯を用いて4,000mJ/cm2の積算光量で紫外線処理を行なった。当該液晶ポリマーフィルムの紫外線処理面を接着面として上記銅張板に積層した。さらに離型材として、表1に示す延伸多孔質PTFEフィルム(ジャパンゴアテックス社製、HRCF−090)を両側に配置し、熱圧着装置(北川精機社製、真空ホット・コールドプレスVH3−1377)を用いて、温度:285℃、圧力:3MPaで5分間熱圧着した。得られた積層フィルムを15×130mmの長方形に切断し、試験片とした。
離型材として、表1に示すポリイミドフィルム(東レ・デュポン社製、カプトン200EN)を延伸多孔質PTFEフィルムの代わりに使用した他は上記製造例1と同様の方法によって、積層フィルムを製造した。さらに、当該積層フィルムを切断して、製造例1と同様の試験片を得た。
上記製造例1で用いた延伸多孔質PTFEフィルム(ジャパンゴアテックス社製、HRCF−090)を3枚重ね、熱圧着装置(北川精機社製、真空ホット・コールドプレスVH3−1377)を用いて、温度:330℃、圧力:4MPaで5分間熱圧着することによって、無孔化したPTFEフィルムを得た。
JIS C6471に従って、上記製造例1および比較製造例1と2で得た試験片について、耐折性試験を行なった。詳しくは、MIT試験機(東洋精機製作所製、MIT−D)に試験片を取り付け、R=0.4、荷重:500gの条件でフィルムが破断するまでの直線回路に平行な方向(MD)と直交する方向(TD)の折り曲げ回数を測定した。また、当該試験前における熱圧着による回路パターンの変形の有無と、試験後における回路面保護層(最表面の液晶ポリマーフィルム)の剥離の有無を確認した。結果を表1に示す。
また、延伸多孔質PTFEフィルムを離型材として用いた場合における積層板の耐折性は、他の素材を離型材とした場合よりも顕著に向上している。これは、延伸多孔質PTFEフィルムはほとんど水分を含まず、且つ多孔質であることから液晶ポリマーフィルム由来の水分を熱圧着時に放出することによって、液晶ポリマーの加水分解を抑制したことによるものである。
