Abstract
【解決手段】プラスチック製シートからなる基材シート1の片面もしくは両面に、未加硫ゴム系組成物を主成分とする金型クリーニング材料2が、エア抜き用空隙を有する所定のパターンに突設されている。
【選択図】図1
Description
基材シートとして、穿孔処理されたもの,穿孔処理されてないもの,多孔質シートを準備した。そのうち穿孔処理されたものとして、ポリエチレンテレフタレート製フィルム,ポリイミド製フィルム,ポリエチレンナフタレート製フィルム,ナイロン6製フィルム,ポリプロピレン製フィルムを準備し、穿孔処理されてないものとして、ポリエチレンテレフタレート製フィルム,ナイロン12製フィルムを準備し、多孔質シートとして、ポリプロピレン製多孔質シート(日東電工社製)を準備した。なお、上記穿孔処理は、直径1mmの円形の孔を縦横に2mmピッチで形成する処理とした。また、いずれの基材シートも厚みを50μmとした。
エチレンプロピレンゴム100部、シリカパウダー50部、酸化チタン5部、有機過酸化物〔n−ブチル−4,4−ビス(t−ブチルパーオキシ)バレレート〕2部、イミダゾール{2,4−ジアミノ−6−〔2′−メチルイミダゾリル−(1′)〕エチル−s−トリアジン}10部、モンタンワックス5部を混練機で混練し、金型クリーニング材料を調製した。
上記基材シートの両面に、上記金型クリーニング材料を、下記の表1に示すパターン(帯状,格子状,斑点状)および寸法(幅,厚み,隙間)に突設させた。
上記基材シートの両面に、上記金型クリーニング材料を、一様な平面状(均一厚みのシート状)に形成した。
このようにして得られた実施例1〜8および比較例1〜3の各金型再生用シートを用いて、金型のクリーニングを行った。この金型は、半導体素子を樹脂封止する際に用いるトランスファー成形用金型であり、上金型と下金型とからなり、これら上金型と下金型の各型面(対向面)は24mm×91mmの長方形となっている。また、型締めした状態での各キャビティの形状は直方体状であり、その寸法は4mm×5mm×2mm(高さ)である。また、キャビティは16個形成されており、それらが8個ずつ2列に並列状に配置されている。この2列の間隔は10mmであり、各列において隣り合うキャビティの間隔は1mmである。そして、充填率の評価は、上記16個のキャビティのうち最も充填性が悪いキャビティの充填率について行った。また、充填率は、キャビティの底面積と、クリーニングによりキャビティ形状に加熱成形された加硫ゴムの底面積との比率により求めた。なお、上記クリーニングの条件は、金型再生用シートの寸法を上記型面と同じとし、金型の型締めギャップを0.5mmとし、成形温度を175℃とし、成形時間を5分間とした。
上記充填率が100%のものは、キャビティの隅々までクリーニングができたため、○と評価し、上記充填率が100%未満のものは、キャビティのクリーニングが不充分であるため、×と評価し、下記の表1,2に併せて表記した。
2 金型クリーニング材料
