A new lead(Pb)-free solder material for automotive glass terminals is developed. In order to satisfy the regulation of EU ELV(End of Life Vehicle), the leaded solder in automotive glass should be replaced by lead-free solder. However, due to the unique property of the glass, it is easily broken with general electric lead-free solder material. As a result of the trying 120 types of solder material, we finally developed the excellent lead-free solder composition which has minimum Indium(In) contents. It is the optimized solder material against the wide range of thermal change environment. There is no glass crack with the developed lead-free solder. And it also shows good bonding strength enough to satisfy the automotive test standard.
