A phantom or dummy component (1) having an array of connection terminals of an actual component simulated by locations (8) on its bottom face, the locations corresponding in size and geometry to the terminals of an actual component, and differing in certain reflection characteristics from the background of the bottom face. At least part of the locations (8) specifically have a different reflection characteristic from the remaining locations or more specifically, groups (4-7) of adjacent locations (8) have different reflection characteristics.
