A surface mount component outer surface inspection system comprising a loader for assembling an inventory of surface mount components and feeding them outward in controlled rectilinear manner and in a timed sequence, a first transfer assembly including a first moving endless belt in racetrack pattern, the belt having a partially perforated outer surface and a vacuum pulled through the perforations from the outer surface along a portion of the belt, for receipt of and retaining the surface mount components from the loader in spaced-apart arrangement on the belt, a surface-mount component, upper-surface viewing device for bringing the exposed surfaces of the moving components into focus at an area for inspecting them for visual defects, a second transfer assembly including a second moving endless belt in racetrack pattern, the belt having a partially perforated outer surface and a vacuum pulled through the perforations from the outer surface along a portion of the belt, the second assembly adjacent the first endless belt located outside of the vacuum area of the first belt and spaced-apart from the upper-surface viewing device, for receipt of the surface-mount components on the opposite sides thereof from the first belt surface in similar spaced-apart arrangement, a surface-mount component, lower-surface viewing device for bringing the exposed surfaces of the components into focus at an area for inspecting them for visual defects, and means for determining the location of surface-mounted components that have failed the visual inspection and following same to a point where the failed components can be separated from other, successfully tested components on the second transfer assembly.
