Abstract
Description
リードフレームやチップが搭載された基板等の成形対象物は樹脂封止することにより電子部品として用いられる。成形対象物を樹脂封止する技術の一つとして、BGA(ball grid array)やQFN(quad flat non-lead)等の基板を樹脂封止して半導体パッケージを製造するトランスファ方式がある。このトランスファ方式は、チップが搭載された基板等を成形型のキャビティに収容し、成形型のポットに粉粒体状樹脂を固めた樹脂タブレットを供給して加熱、溶融した後、該成形型を型締めした状態で樹脂タブレットが溶融した溶融樹脂をキャビティに供給して硬化させ、型開きして樹脂成形品を製造する方式である。
図1〜図8を用いて樹脂成形品の製造方法について説明する。
以下、上述した実施形態と同様の部材については、理解を容易にするため、同一の用語、符号を用いて説明する。
上述した実施形態では、フェイスアップのトランスファ方式で説明したが、フェイスダウンのトランスファ方式として、基板S等の成形対象物を上型UMに固定し、キャビティMCを下型LMに設けても良い。
以下、上述の実施形態において説明した成形型C、樹脂成形装置D及び樹脂成形品の製造方法の概要について説明する。
