Abstract
According to aspects of the disclosed subject matter, a method of placing a solid state light source on a heat sink can include coating a surface of the heat sink with an anodized coating or an e-coating, for example. A portion of the coated surface can be treated via laser ablation for placing the solid state light source. Additionally, the laser ablation parameters can be adjusted to provide a predetermined roughness to the treated portion of the coated surface.
