The Taguchi method has been used to identify the optimal process parameters of marking integrated circuit (IC) packages with a 400 W flashlamp-pumped pulsed Nd:YAG laser that is incorporated onto a Maho Lasercav 5-axis CNC (Computer-Numerical-Control) machine. Three types of packages, namely, the leadless chip carriers, ceramic packages, and epoxy packages have been marked successfully.
