Embodiment Construction

[0045]In general, there is a preferred alignment between two parts when they are secured together to make a composite device. In some cases, there are most and least preferred alignments and acceptable alignment ranges. With regard to the preferred alignment, the operation of the combined device is significantly improved. Operation was satisfactory with an acceptable alignment range. Finally, the operation is unsatisfactory for the least preferred alignments. More specifically, industry-known criteria will determine whether alignment yield is the most preferred outcome. Therefore, each type of combination device will have its own acceptance criteria.

[0046] A method for assembling a composite device is disclosed, comprising securing together two parts, where each part contains a set of components with a given spacing, the spacing between the components on the two parts being different. A subset of the combined components is then selected such that the tolerances between ...

Abstract

A method of making a composite device, includes providing a first part including a first set of components at a first pitch; along with providing a second part including a second set of components at a second pitch, different from the first pitch. The first part is fastened to the second part to make a composite device. The composite device includes a subset of the first set of components that are substantially aligned to a subset of the second set of components to form a corresponding subset of substantially aligned composite components.

Description

technical field [0001] The present invention generally relates to a composite device comprising a first part and a second part assembled together, wherein components of the first part are precisely aligned with corresponding components of the second part. Background technique [0002] Early inkjet printheads were fabricated by aligning a nickel nozzle plate with an ejector substrate. Precise alignment of the nozzles on the nozzle plate with the ejectors on the ejector substrate is critical in order for the multiple nozzles to eject ink droplets very uniformly in a given direction. As inkjet nozzle density and resolution increased, drop-on-demand inkjet printheads evolved to use microelectromechanical systems (MEMS) technology to construct nozzles directly on top of the bubble chambers. This greatly improves the accuracy of the inkjet printhead and significantly reduces the cost of alignment. For small arrays where images are printed on a page by moving back and forth, such...
