Design and development of high precision five-axis positioning system for roll-to-roll multi-layer microcontact printing
(Massachusetts Institute of Technology, 2009)
Microcontact printing is based on the use of elastomeric stamps to transfer ink onto a substrate taking advantage of the self-assembly process. Features as small as 300nm can be easily printed over an extended area. The ...
Design and development of high precision elastomeric-stamp wrapping system for roll-to-roll multi-layer microcontact printing
(Massachusetts Institute of Technology, 2009)
Microcontact printing is an emerging printing technique that could potentially find application in the electronics industry. High-speed roll-to-roll equipment was built at Nano Terra, Inc in 2008, for microcontact printing. ...
Analysis of the capabilities of continuous high-speed microcontact printing
(Massachusetts Institute of Technology, 2008)
Microcontact printing uses elastomeric stamps to transfer ink onto a substrate by the process of self-assembly. It has the capability to print features as small as 200nm over large areas. Because of this it has many potential ...
Management of a high mix production system with interdependent demands : simulation of proposed policies
(Massachusetts Institute of Technology, 2009)
The finished goods inventory management in the accessories area of a material testing company is complex. There is interdependence between the demands of products and they can be sold both as part of systems and as individual ...
Elimination of PZT thin film breakage caused by electric current arcing and intrinsic differential strains during poling
(Massachusetts Institute of Technology, 2012)
Historically, substrate breakage during the poling process has been responsible for a 2% yield loss for a contract manufacturer specializing in volume production of lead zirconate titatate (PZT) thin film devices. In this ...
Reduce cycle time and work in process in a medical device factory : scheduling of needle hub molding machines
(Massachusetts Institute of Technology, 2007)
Many manufacturing firms have improved their operations by implementing a work-in-process (WIP) limiting control strategy. This project explores the application of this concept to limit WIP and reduce cycle time for the ...
Lean manufacturing in a mass customization plant : improvement of Kanban policy and implementation
(Massachusetts Institute of Technology, 2011)
This thesis documents the application of the principles of lean manufacturing and supply chain planning at Varian Semiconductor Equipment Associates. Varian is a manufacturer of ion implantation machines, and supplies and ...
Root cause analysis of solder flux residue incidence in the manufacture of electronic power modules
(Massachusetts Institute of Technology, 2011)
This work investigates the root causes of the incidence of solder flux residue underneath electronic components in the manufacture of power modules. The existing deionized water-based centrifugal cleaning process was ...
Robustness and repeatability of interdigitated electrodes on a substrate tested in an aqueous environment
(Massachusetts Institute of Technology, 2011)
Interdigitated electrodes are currently being used as sensing components in microfluidic lab-on-a-chip devices. The Daktari Diagnostics system uses these electrodes to measure the change in impedance of a fluid in an assay ...
Cleaning process development and optimization in the surface mount assembly line of power modules
(Massachusetts Institute of Technology, 2011)
The cleaning process in the surface mount assembly line of power modules had been found to insufficiently remove solder flux residue from printed circuit board (PCB) assemblies after the process of reflow soldering. This ...
