Paper Abstract

In fiber-optic component attachment using laser welding, the welding-induced-alignment-distortion (WIAD) is an issue significantly affecting the packaging yield. Our previous investigation has shown that an elimination or minimization of WIAD is possible if the relevant laser welding process parameters such as welding sequence can be optimized. In this work, a more realistic physics based laser welding model is introduced and incorporated into our finite element analysis model by a few user subroutines, the effect of welding sequence on WIAD in a butterfly laser diode module package is evaluated. The result verifies the conclusion that the effect of laser welding sequence on WIAD for butterfly laser diode packages is significant and WIAD control can be achieved as appropriate welding sequence is employed.
