Paper Abstract

In this work, a laser welding process for attaching conducting ribbons to a miniaturized feedthru is introduced. A pulsed 1064nm Nd:YAG laser was used as an example in this study. A numerical simulation by means of finite element method (FEM) for the prediction of temperatures in the feedthru assembly is presented. The approach used was intended to solve the energy balance equation with appropriate initial and boundary conditions. A laser weld joint strength test was conducted using a Mechanical Strength Tester. The influence of processing parameters, such as laser power and pulse duration, on the temperature distribution and the weld joint strength are investigated and discussed.
