図2は、樹脂成形装置を示す模式図である。
図3は、フィルム供給機構の移動機構を示す模式図である。
図4は、樹脂成形品の製造方法を示す模式図である。
図5は、フィルム搬送機構の制御フロー図である。
図6は、別実施形態における樹脂成形装置を示す模式図である。
以下、トランスファ方式の樹脂成形装置を一例として説明する。図1には、本実施形態における樹脂成形装置30を備えた樹脂成形ユニットDの模式図が示されている。樹脂成形ユニットDは、成形モジュール3と供給モジュール4と制御部6と搬送機構とを備えている。成形モジュール3は、成形対象物を樹脂封止するための樹脂成形装置30を有している。制御部6は、少なくとも樹脂成形装置30の作動を制御するソフトウェアとして、HDDやメモリ等のハードウェアに記憶されたプログラムを含んでおり、コンピュータのASIC,FPGA,CPU又は他のハードウェアを含むプロセッサにより実行される。
図2には、本実施形態における樹脂成形装置30が示されている。樹脂成形装置30は、水平面に載置されて重力により不動状態で固定された固定フレーム3Aと、固定フレーム3Aに支持された成形型Cと、固定フレーム3Aに支持された可動プラテン34と、可動プラテン34を移動させて成形型Cを型締めする型締め機構35と、離型フィルムFを供給するフィルム供給機構1と、を備えている。なお、「固定フレーム3Aに支持される」とは、固定フレーム3Aに対して相対移動可能に固定フレーム3Aにて直接的又は間接的に支えられている状態を意味し、以下同様である。
図1~図2及び図4~図5を用いて、樹脂成形品の製造方法を説明する。樹脂成形品(成形済基板Sb)の製造方法は、フィルム供給機構1により上型UMと下型LMとの間に離型フィルムFを供給するフィルム供給工程と、型締め機構35により成形型Cを型締めする型締め工程と、成形型Cに成形前基板Sa及び樹脂材料(樹脂タブレットTを溶融させた樹脂)を供給して樹脂成形を行う成形工程と、を含んでいる。フィルム供給工程は、フィルム供給機構1が離型フィルムFを搬送するとき、フィルム供給機構1が離型フィルムFを搬送する方向と同じ方向に送出ロール11aを回転させる。このとき、制御部6は、離型フィルムFのフィルム幅が許容範囲内となるように、離型フィルムFが巻かれた送出ロール11aの回転速度Naを制御する。
その結果、第二送出ローラ14bより送出ロール11a側と、搬送ローラ16aより回収ロール12a側とでは、離型フィルムFがほとんど移動しない。よって、離型フィルムFの搬送ラインがずれるといった不都合がない。
