Embodiment Construction

[0047] The following description is only an exemplary description in nature, and is not intended to limit the disclosure, application or use of the present invention.

[0048] The terms "fluid manufacturing material" and "fluid material" as defined herein may be broadly construed to include materials capable of taking on a form of low viscosity and suitable for being deposited (e.g. from A PDM head deposits onto a substrate to form a microstructure). Fluid fabrication materials may include, but are not limited to, Light Emitting Polymers (LEPs) that may be used to form Polymer Light Emitting Diode display devices (PLED, PolyLED). Fluid fabrication materials can also include plastics, metals, waxes, solders, solder pastes, biomedical products, acids, photoresists, solvents, adhesives and epoxies. The term "fluid manufacturing material" is interchangeably referred to herein as "fluid substance".

[0049] The term "deposition" as defined herein generally refers to the process b...

Abstract

According to the present disclosure, a printer apparatus (10) may include a chuck (16)configured to support a substrate thereon, a rail (24, 26) spaced apart from the chuck (16), a printhead carriage frame (14) coupled to the rail (24, 26) and containing a printhead carriage housing at least one printhead (40) therein, a first camera assembly (17) configured to capture image data of the printhead (40) and provide the image data to a computer, and a computer receiving the image data from the first camera assembly (17) and configured to determine a deviation between a desired position of the printhead (40) and an actual position of the printhead (40).

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Application Nos. 60 / 674,584, 60 / 674,585, 60 / 674,588, 60 / 674,589, 60 / 674,590, 60 / 674,591, and 60 / 674,592, filed April 25, 2005 benefit. The disclosures of the aforementioned applications are incorporated herein by reference. technical field [0003] This application relates to piezoelectric microdeposition (PMD) devices, and more particularly to printhead alignment assemblies suitable for PMD devices. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] In industrial PDM applications, drop placement accuracy is very important. Inaccuracies in drop placement are caused by a variety of causes. These causes may include misalignment between printheads within an array, as well as misalignment of the substrate on which they are printed. Manual adjustments of p...
