An apparatus for accurately locating a micro-electronic chip in a chip-holding cavity for visual testing, the chip having at least a front wall and a pair of opposed, spaced-apart side walls, wherein the front wall meets with each of the side walls to form opposed, spaced-apart first and second front edges, comprising a cavity side wall formed to juxtapositionally about at least one of the side walls of the chip, the cavity side wall having formed therein a depression creating a shadow projecting forward from the depression, wherein the first front edge of the chip forms a border of the shadow to form an objectively measurable contrast in grayness between the shadow and the chip. |
