Description
図1は本発明の実施の形態1の電子部品搭載装置の正面図、図2、図3は本発明の実施の形態1の電子部品搭載方法の工程説明図、図4は本発明の実施の形態1の電子部品搭載方法におけるフラックス転写過程の説明図、図5は本発明の実施の形態1の電子部品搭載方法における半田接合過程の説明図、図6は本発明の実施の形態1の半田付方法においてフラックスに混入される金属粉の断面図である。
16のサイズとしては、代表サイズが0.05μm〜20μmの範囲のものが望ましく、基剤中への混合割合は、1〜20vol%の範囲が望ましい。
ンプ7を溶融させて基板12の電極12aに半田付けする。なお図4,図5は、図2(b)におけるA部詳細、図3(b)におけるB部詳細をそれぞれ示している。
7aを除去する作用を発揮するが、前述のように酸化膜7aを突き破った溶融半田が金属粉16に沿って濡れ拡がることにより、酸化膜7aが部分的にのみ除去されている場合においても良好な半田接合性が確保されるため、フラックス10中に含まれる活性剤には強い活性作用は要求されない。
粉の配合割合を低く抑える必要があり、この結果溶融半田を導く効果が良好に実現されない事態が生じていた。
図7は本発明の実施の形態2の電子部品搭載装置の正面図である。本実施の形態2は、実施の形態1において単一の部品移載機構4によって行っていた電子部品6へのフラックス転写動作と電子部品6の基板12への搭載動作とを、それぞれ専用の部品移載機構によって行うように構成したものである。
