[実施例、比較例]
エポキシ樹脂を含むバインダー成分100質量部に対して、硬化剤、金属粒子、及び溶剤を表1に記載された割合で配合して混合し、導電性塗料を得た。使用した各成分の詳細は以下の通りである。
液体エポキシ樹脂1:グリシジルアミン系エポキシ樹脂、(株)ADEKA製、商品名「EP−3905S」
液体エポキシ樹脂2:グリシジルエーテル系エポキシ樹脂、(株)ADEKA製、商品名「EP−4400」
(メタ)アクリレート樹脂:2−ヒドロキシ−3−アクリロイロキシプロピルメタクリレート、共栄社化学(株)製、商品名「ライトエステルG−201P」
硬化剤1:フェノールノボラック、荒川化学工業(株)製、商品名「タマノル758」
硬化剤2:1−シアノエチル−2−メチルイミダゾール、四国化成工業(株)製、商品名「2MZ−CN」
硬化剤3:ナフトール系硬化剤、群栄化学工業(株)製、商品名「GPNX−70HN」
比較硬化剤:アミン系硬化剤、味の素ファインテクノ(株)製、商品名「アミキュア PN−23」
溶剤:酢酸ブチル
金属粒子:フレーク状銀コート銅粉、銀被覆量5質量%、平均粒径5μm、タップ密度6.3g/cm3,5.6g/cm3,5.3g/cm3,5.0g/cm3
上記各実施例及び比較例で得られた導電性塗料(液温25℃)の粘度測定をTVB−10型粘度計又は円錐平板型回転粘度計で行った。TVB−10型粘度計での測定は、スピンドルNo.5を用いて、回転数10rpmで行った。円錐平板型回転粘度計での測定は、ブルックフィールド(BROOK FIELD)社の商品名「プログラマブル粘度計DV−II+Pro」、コーンスピンドルCP40を用いて、0.5rpmで行った。測定された粘度を表1に示す。なお、粘度の欄の「−」は、その粘度計では測定不能であることを示す。
図3に示すように、銅パッド21を設けたガラスエポキシ基板の塗布箇所以外ポリイミドテープでマスキングし、ハンドスプレー(アネスト岩田(株)製、LPH−101A−144LVG)により各実施例及び比較例で得られた導電性塗料を塗布し、80℃で60分間予備加熱した後、160℃で60分間加熱することにより本硬化させ、ポリイミドフィルムを剥離する事により、銅パッド21間の長さ(図3におけるx)60mm、幅(図3におけるy)5mm、厚さ10μmの導電性塗膜22を得た。この硬化物サンプルにつき、テスターを用いて両端の抵抗値Rを測定し、次式(1)によりシート抵抗を計算した。N=5で試験を行い、その平均値を求めた。シート抵抗が100mΩ/□以下であれば、導電性が良好であると判断した。
上記で得られた硬化物サンプルにつき、ポリイミドフィルムを剥離した部分のガラスエポキシ基板の厚さと、その剥がした部分に隣接する導電性塗膜22が形成されたガラスエポキシ基板の厚さをそれぞれマイクロメーターで測定し、後者から前者を引き算することにより、導電性塗膜22の厚みを求めた。粘度が低いものに関しては、重ね塗りを行い10μmの膜厚としたが、1回の塗布で12μm以上となったものは、「×」とした。
ガラスエポキシ基板(FR−4)を用いて、幅15mm×長さ15mm×厚さ1mmのダミーチップを作製した。そのダミーチップの半分をポリイミドフィルムでマスキングし、粘着テープを用いて10mm間隔で碁盤目状に固定し、回転台の上に載せ160rpmで回転させながら、ハンドスプレー装置(アネスト岩田(株)製、「LPH−101A−144LVG」)を用いてスプレー塗布試験を行った。スプレー塗布後に80℃で60分間溶剤を乾燥し、160℃で60分間加熱し、硬化させた。硬化後の塗膜について、均一性を評価した。
シールド層とパッケージ表面又はグランド回路との密着性の評価として、JIS K 6850:1999に基づくせん断強度を測定した。具体的には、幅25mm×長さ100mm×厚さ1.6mmの銅板に導電性塗料を長さ12.5mmの領域に塗布し、常温で5分間放置して溶剤を乾燥させた後、その上に幅25mm×長さ100mm×厚さ1.6mmの銅板を貼りあわせた。次いで、80℃で60分加熱し、さらに160℃で60分間加熱して銅板同士を接着させた。次いで、引張り強度試験機((株)島津製作所社製、商品名「オートグラフAGS−X」)を用いて接着面を平行に引張り、破断した時の最大荷重を接着面積で除してせん断強度を計算した。せん断強度が3.0MPa以上であれば問題なく使用できる。
