Local and  global vision alignment is used for nested substrates and feature alignment. The software must allow the user to align die relative to substrate fiducials, die edges, or features of previously placed die. The alignment of the laser chip to photo diode or a lens to a VCSEL are common photonic examples.  Another example is the alignment of critical die such as MMICs and beam lead diodes.  This capability ensures repeatability and precise alignment of optical and microwave devices.

Programmable Multi-color Lighting

Multi-colored lighting is required to successfully vision process a wide range of materials.  Tri color; red, green and blue programmable lighting provides the capability for processing challenging alignment surfaces, such as gold traces on alumina.  Lighting intensity must be programmable and include both ring and collimated lights for a complete lighting solution. It must be possible to individually program optimal light settings for each die and substrate fiducial alignment.
