Description
図2(a)に示すように、ポリイミドフィルム1上にFPC端子2と配線層2’及び絶縁層7の積層体とが形成されたFPC5を準備する。
(接着部形成工程)
図2(b)に示すように、非導電ペースト4が充填された接着剤供給手段3’を用いて、FPC5の実装領域8上に、互いに離間した状態で非導電ペースト4を供給する。
FPC5の裏面から基板ごと加熱したり、FPC5の表面からホットエアーを吹き付けたりすることにより、接着部9aの温度が60〜90℃程度になるように加熱して、図2(c)に示すように、実装領域8cの全面に均一に設けられた接着層9cを形成する。
図2(d)に示すように、接着層9cが形成された実装領域8cを有するFPC5のFPC端子2と、ベアチップ10のバンプ6とを位置合わせして、ベアチップ10の背面(配線面とは逆側の面)に圧着ツール(不図示)をあてがって、接着層9cの温度が240℃になるように、圧力90MPaで3〜5秒間、ベアチップ10を加熱及び加圧する。
