6 2001-04-11 6 ICOS Vision: inspection of IC leads Dual shadow vision system guarantees reliable and accurate 3D measurements on all the leads. Dual shadow vision system guarantees reliable and accurate 3D measurements on all the leads. Switching lights eliminate the need for multiple sensors or motion. Switching lights eliminate the need for multiple sensors or motion. Where as single projection systems only look at the side of the leads, the ICOS solution reconstructs a true 3D image of the component. Where as single projection systems only look at the side of the leads, the ICOS solution reconstructs a true 3D image of the component. These raw 3D data are further analyzed to calculate reference planes and specific measurements such as lead coplanarity These raw 3D data are further analyzed to calculate reference planes and specific measurements such as lead coplanarity
