First and second chiplets are positioned along a surface to respectively cover first and second electrodes. The first electrode is activated to cause an attraction force between the first electrode and the first chiplet. The second electrode is deactivated allowing the second chiplet to rotate on the surface. While the first electrode is activated and the second electrode is deactivated, a rotation field is applied to cause the second chiplet to be oriented at a desired orientation angle, the first chiplet being prevented from rotating by the attraction force.
