Abstract
A component carrier, for holding for purposes of automated visual inspection an electrical component having a lead with a free end, includes a carrier substrate and a pocket recessed in the substrate for holding the component in the interior of the pocket. The pocket includes a wall, depending from the carrier substrate and defining a lateral boundary of the pocket, and a bottom. There is a lead-tip horizontal plane and a lead-tip vertical plane when a correctly constructed component of the type the carrier is intended to hold is properly oriented in the pocket. The lead-tip vertical plane is perpendicular to a longitudinal axis of the pocket. The wall slopes down and inwardly at a first angle relative to the substrate through the lead-tip horizontal plane and at a second angle relative to the substrate through the lead-tip vertical plane. The first angle is greater than or equal to approximately 75.degree. and less than or equal to 90.degree., and the second angle is less than 90.degree. and not greater than the first angle.
