[PDF] Defect Detection of Gold-Plated Surfaces on PCBs

Connector fingers are metallic pads at the edge of a printed circuit board (PCB). They must be inspected after plating to ensure that an adequate coating of gold has been applied. The gold-plated surface is not uniform, but produces a homogeneous texture in the image. In this paper, we propose two entropy measures of chromatic and structural regularities for the automatic defect
