A system is disclosed, which comprises a component carrier having a first side, and a second side opposite the first side; and a light source to couple light into the carrier. In an example, the carrier is to propagate, through internal reflection, at least a portion the light to both the first and second sides of the carrier. The portion of light may be sufficient to release a first component and second component affixed to the first and second sides of the carrier via a first photosensitive layer and second photosensitive layer, respectively.
