(a)一分子中に2個以上のエポキシ基を有するエポキシ樹脂と、
(b)前記(a)成分であるエポキシ樹脂と共通の溶媒に分散可能な数平均分子量が2000以上10000未満のポリカルボジイミド樹脂と、
(c)イミダゾール系硬化剤と、
を必須成分として含有する樹脂組成物を前記溶媒に分散させることによってワニスを調製し、前記ワニスを織布又は不織布である基材に含浸させた後に乾燥させることを特徴とするものである。
エポキシ樹脂として、ダウ・ケミカル社製臭素化エポキシ樹脂「DER530A80」(エポキシ当量430g/eq、固形分濃度80wt%)のアセトン溶解液と、東都化成社製リン変性エポキシ樹脂「FX305EK70」(エポキシ当量500g/eq、固形分濃度70wt%)のメチルエチルケトン溶解液とを用いた。
エポキシ樹脂として、臭素化ビスフェノールA型エポキシ樹脂(東都化成社製「YDB−500」:エポキシ当量500g/eq)、クレゾールノボラック型エポキシ樹脂(東都化成社製「YDCN−220」:エポキシ当量220g/eq)を用いた。
接着シート(基材なしフィルム)として、ニッカン工業社製「ニカフレックスSAFD」(厚さ:40μm)を用いた。
基材である織布として、日東紡績社製ガラスクロス2116タイプ「WEA116E」(厚さ0.1mm)を用い、また、基材である不織布として、アラミド繊維不織布(デュポン社製「サーマウント」坪量30g=厚さ0.04mm)を用いた。
10cm角の接着シートをカッターナイフで5mm幅に短冊状に10本切り出し、切り出した端面から発生した樹脂粉の質量を測定した。
厚さ0.2mmの積層板(松下電工社製「R−1766」:銅箔の厚さ35μm)の表面の銅箔をエッチングで除去することによって回路形成し、さらに内層処理(黒化処理)を施した。この積層板とフレキシブルプリント配線板(松下電工社製「R−F775」:銅箔の厚さ18μm)との間に接着シートを層間絶縁材料として介在させて積層し、プレスの成形最高温度180℃で90分間加熱しながら、2.94MPaで加圧することによって、図2に示すような多層配線基板を製造した。そして、内層回路が形成されている部分におけるボイドの発生の有無を確認した。
成形後の厚さが1.6mmとなるように、接着シートの両面に銅箔を配置したものをプレスの成形最高温度180℃で90分間加熱しながら、2.94MPaで加圧して積層成形することによって、両面銅張積層板を作製した。そして、この両面銅張積層板の表面の銅箔を全面エッチングして測定試料を作製し、この測定試料について、JIS C6481に準拠して弾性率を測定した。
