Due to the low coefficient of thermal expansion (CTE) and high wear resistance, Al-Si alloys are used in electronic packaging. However these Al-Si alloys are difficult to weld and attempts had been made to weld these alloys using laser welding. Severe defects occurred during the welding process whic...
