shrinkage joint 中文意思是什麼
shrinkage joint
解釋
冷縮節理-
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
這種封裝技術最大的缺點是會使激光二極體的封裝產生焊後偏移( pws ) ,很少有一種機械的方法可以校正這種焊後偏移到亞微米級別,目前激光錘被證明是一種很有效的校正方法,激光錘校正作用過程就是利用金屬熔化凝固冷卻產生的內應力來恢復焊後偏移的過程。 -
