However , the disadvantage of laser welding is the so - called post - weld - shift ( pws ) . the end result is a reduction in light coupling efficiency . the shrinkage force generated by the solidification process is so great that no known mechanical structure can counteract the shrinkage from shifting the joint ? at least at the micron level
这种封装技术最大的缺点是会使激光二极管的封装产生焊后偏移( pws ) ,很少有一种机械的方法可以校正这种焊后偏移到亚微米级别,目前激光锤被证明是一种很有效的校正方法,激光锤校正作用过程就是利用金属熔化凝固冷却产生的内应力来恢复焊后偏移的过程。
