Laser-Heating Effects in Laser-Induced Plating

Abstract

This paper describes the effects of laser heating on the electroless plating process. In the experiment, a focused YAG laser beam and a copper electroless plating solution were used. In the analysis, the temperature distribution was calculated by the solution of the heat conduction equation. In the first stage on the laser-induced plating, the rapid heating effect induces the nucleation reaction. In the second stage, the partially heating effect enhances the reduction reaction based on the micro-convection, which depends on the sharp temperature profile.
