Lighting Systems

The substrate and component to coincide are lit and can be dimmed separately to help find the best picture of the dual image overlay.

FINEPLACER^® standard lighting (not for A6 and A7) consists of two halogen lamps (10W) for illuminating the substrate, and another two for illuminating the underside of the component (head).

Head and target lamps are arranged twofold symmetrically to avoid asymmetrical reflections from rows of shiny balls or pads.

Using camera systems with very high magnification, or handling complicated chips or substrates may demand very bright light that the standard lighting cannot provide. Using fibre optics, the light of more than a 100 W halogen lamp is given without heating up the chips in an uncontrolled way.

If fibre optic lighting is required, the FINEPLACER® will be equipped with fibre optic conductors instead of standard halogen lamps; 2 arms directed to the substrate and 2 arms to the component.

Achieving visible representation of normally hardly perceptible Indium Tin Oxide (ITO) structures on glass (e.g. LCD Displays), or of very small components, this special illumi-nating device feeds the light directly into the optical axis of the system.
