Description
(基板の実施例1)
市販人造黒鉛材(密度:1.85g/cm3)から、100mm×100mm×70mmのブロックを70mm厚方向に黒鉛粒子が配向する様に切り出した。得られた成形体は、電気炉で窒素雰囲気中、温度700℃に予備加熱した後、予め加熱しておいた内径Φ300mm×300mmtのプレス型内に収め、シリコンを12質量%含有するアルミニウム合金の溶湯を注ぎ、100MPaの圧力で20分間加圧して、成形体にアルミニウム合金を含浸させた。次に、室温まで冷却した後、湿式バンドソーでアルミニウム合金及び鉄製容器部分を切断し、100mmL×100mmW×70mmHの黒鉛−アルミニウム合金複合体を得た。得られた複合体は、含浸時の歪み除去の為、温度500℃で2時間のアニール処理を行った。
粒子径0.1mm〜2mmの人造黒鉛粉末1600gとメディアン径7μmの炭化珪素粉末(大平洋ランダム社製/NC#2000)600gとをV型混合機にて混合した後、内径寸法が100mmL×100mmW×150mmHの鉄製容器に充填し、面圧100MPaの圧力で成形して、100mmL×100mmW×90mmHの成形体を作製した。得られた成形体は、鉄製容器ごと電気炉で窒素雰囲気中、温度700℃に予備加熱した後、予め加熱しておいた内径Φ300mm×300mmtのプレス型内に収め、シリコンを12質量%含有するアルミニウム合金の溶湯を注ぎ、100MPaの圧力で20分間加圧して、成形体にアルミニウム合金を含浸させた。次に、室温まで冷却した後、湿式バンドソーでアルミニウム合金及び鉄製容器部分を切断し、100mmL×100mmW×90mmHの黒鉛−炭化珪素−アルミニウム合金複合体を得た。得られた複合体は、含浸時の歪み除去の為、温度500℃で2時間のアニール処理を行った。
(1)金属層12および/または絶縁層13の積層面側に、接着剤を塗布して接着層を設けて構成でき、これにより接合力を強化できる。また、図3に示すように、樹脂部151と第1、第2パターン金属部152、153との両方或いはいずれか一方の積層面側に接着剤を塗布して接着層31を設けて構成でき、これにより接合力を強化できる。
