Abstract
【解決手段】基板1の端部に設けられた細長形状の電極2にフレキシブル基板3の端部に設けられた細長形状のリード4を接合する接合方法において、接合位置に樹脂接着材8が供給された基板1にフレキシブル基板3を搭載し、プリコート半田6が形成されたリード4を電極2に当接させて樹脂接着材8を基板間隙間部を通じて接合部から流出させ、電極2に対してリード4を押圧するとともに接合部を加熱することにより電極2とリード4の当接面を金属間接合する。そして流出した樹脂接着材8を熱硬化させて接合部を補強する樹脂補強部を形成する。これにより、高コストの異方性導電樹脂を使用することなく電極2にリード4を低コスト・高信頼性で接合することができる。
