摘要

激光为焊接接头的形成提供了高度可控和局部化的焊点,是电子工业中锡/铅焊接工艺的宝贵工具,近年来,激光束焊接已成为一种新兴的焊接技术,激光在焊接领域的应用是一种高效率的方法。采用60瓦CO2连续激光器进行焊接实验,实验结果表明,该激光器能显著提高焊接速度和焊接质量。本文通过改变激光的能量比,详细研究了CO2激光与Sn/Pb焊丝的焊接相互作用。同时,研究了激光光斑到材料距离的影响。

Application of CO2 laser for electronic components soldering
Laser provides a high controllable and localized spot for soldering joint formation and this is a valuable tool in Sn/Pb Soldering process on electronic industry, in recent years, laser beam welding has become an emerging welding technique, the use of laser in welding area is a high efficiency method. A 60 Watts CO2 continuous laser was used on this study, during welding experimental results indicated the laser could significantly improve speed and weld quality. In this work, the welding interactions of CO2 laser with Sn/Pb wire have been investigated in details through varying the energy ratios of laser. And at the same time, the effect of distance from laser spot to material.
