摘要
采用BTU隧道炉对Au基共晶焊料(金锡、金锗)的焊接技术及在TR组件应用情况进行研究分析,并进行了显微镜观察、X-ray检测。试验结果表明:通过隧道炉进行的Au基共晶焊料的焊接润湿角小于90°,呈R角,焊透率均能达到95%以上,具有很低的空洞率,剪切强度远大于砷化镓本身材料的强度,生产效率高,能够满足产品的大批量生产应用。
In this paper,Au eutectic solders （Au/Tin,Au/Ge）welding technology and their application in the TR module are analyzed by the BTU conveyor furnace.The experiment pieces are observed by microscope and examined by the x-ray.h is shown that the wetting angle of the gold eutectic solders welding by the BTU conveyor furnace is less than 90° ,presenting R angle.The complete penetrution is higher than 95% and the shear strength is higher than the GaAs oneself material totally.The efficiency is very high and can satisfy the large quantity of product application.
