A deposition device is described. The deposition device has a substrate support and an imaging system disposed to image a portion of a substrate positioned on the substrate support. The imaging system comprises an LED light source and an imaging unit, and is coupled to a deposition assembly disposed across the substrate support.

Substrate positioning for deposition machine

Methods and apparatus are described herein for measurement of droplets dispensed from a printhead of an inkjet printer onto a substrate. An inkjet printer described herein comprises a printhead assembly comprising a printhead and an imaging system, the imaging system comprising a camera and a strobed LED source; and a deposition unit for positioning a substrate to receive droplets dispensed from the printhead and for imaging the droplets using the imaging system and the strobed LED source. Methods described herein comprise dispensing droplets of a liquid from a printhead of a printhead assembly of an inkjet printer onto a substrate; positioning the substrate with respect to an imaging system coupled to the printhead assembly, the imaging system comprising a camera and an LED light source; and imaging the droplets on the substrate by relatively scanning the substrate and the imaging system and strobing the LED light source.

Droplet measurement using strobed LED source

A deposition device is described. The deposition device has a substrate support and a laser imaging system disposed to image a portion of a substrate positioned on the substrate support. The laser imaging system comprises a laser source and an imaging unit, and is coupled to a deposition assembly disposed across the substrate support.

An architecture for current driver circuitry for diode laser systems is contemplated whereby the circuitry is both modular and minimally complex with respect to the number of components and connections.
