摘要: 本发明提供面安装部件的软钎焊方法以及面安装部件。即使在使用安装用软钎料将使用小片焊接用软钎料而形成的面安装部件软钎焊到印刷电路板上时,小片焊接用软钎料也不会发生熔化。作为芯片焊盘用软钎料(30),使用Cu的含有量为规定值以下的、以Sn为主要成分的(Sn—Sb)系高熔点软钎料,作为涂布在电路基板的基板端子部上的安装用软钎料(70),使用(Sn—Ag—Cu—Bi)系软钎料,使用上述安装用软钎料(70)来软钎焊使用上述芯片焊盘用软钎料(30)而形成的面安装部件。由于小片焊接用软钎料(30)的固相线温度是243℃,安装用软钎料(70)的液相线温度是215℃~220℃左右,因此小片焊接用软钎料(30)也不会因回流炉的加热温度(240℃以下)而熔化。
