Description
まず、流体塗布装置のヘッド部1の構成を説明する。図3が本発明によるヘッド部1の詳細を示す図である。ヘッド部1は、溶融はんだ等を収容可能な流体タンク2と、下端に設けた吐出ヘッド3と、を備える。溶融はんだなど温度コントロールが必要な流体に用いるときは、流体タンク2の腹部にヒータ4を巻き付けるなど、加熱手段を取り付けることもできる。吐出ヘッド3には、ヘッド下端に設けた流体吐出ノズル5と吸引口6とを有し、吸引口6は流体吐出ノズル5よりも進行方向に向かって先に吸引工程が実施できるように取り付けられている。流体吐出ノズル5及び吸引口6にも温度コントロールが必要な流体に用いるときは、吐出ヘッド3下端にもヒータ4を取り付けることが可能となる。
以下、本発明の第2実施形態について、第1実施形態と異なる点を中心に説明する。第2の実施形態の構成のうち、特に断らない点については、第1実施形態と同じである。
以下、本発明の第3実施形態について説明する。図3は、第3実施形態による流体塗布装置の一例としてのはんだバンプ形成装置の概略構成を示す模式図である。はんだバンプ形成装置は、電子部品のワーク7(例えば、シリコンウエハやプリント基板等)上に流体9(ここでは、溶融はんだ)を塗布して、はんだバンプを形成する装置である。図3に示すように、はんだバンプ形成装置は、吐出ヘッド部1と、圧力供給手段11と、圧力発生源14と、マイクロエジェクタ16と、圧力発生源19と、流体供給装置22と、を備えている。また、はんだバンプ形成装置は、ステージ30〜32を備えている(図12参照)。これらの詳細については後述する。
