Mechanical characterization and modeling of solder joints for the secondary side reflow of large IC packages

Creator:: Yutzie, James D.
Abstract:: As the drive continues to reduce the size of Printed Wiring Assemblies (PWAs), improve performance of electronic assemblies, and reduce costs of these products, reliable secondary (bottom) side reflow operations must be developed. Attaching Surface Mount Technology (SMT) components to the secondary side of a Printed Circuit Board (PCB) is...

Characterization of a diffusion soldering process for micro-technology-based energy and chemical systems manufacturing

Creator:: Gabriel, Michael A.
Abstract:: Several 316 stainless steel meso-scopic devices were made using a diffusion soldering process. Tensile strength and pressure drop of the devices were measured and metallurgical examinations were made of the joints. Continuous bonds were observed in the sample cross-section specimens. Strengths of the diffusion soldered joints were up to 56%...

Manufacturing Process Design and Electrically-Assisted Embossing of a Microchannel Solar Receiver

Creator:: McNeff, Patrick S.
Abstract:: Manufacturing process design (MPD) represents a design-oriented approach to manufacturing engineering. In this dissertation, Haynes 230 (H230), a solid solution-strengthened Ni-based superalloy, was chosen to meet the material requirements of a microchannel solar receiver (MSR) needed to increase the efficiency and reduce the cost of solar thermal power generation. An...

Manufacturing Process Design for a Stamped Microchannel High-Temperature Recuperator

Creator:: Song, Chuankai
Abstract:: Microchannel high temperature recuperators have the advantage of higher heat transfer coefficients and lower size and weight than traditional high temperature recuperators. However, the industrial application of microchannel recuperators are restricted by the high cost of photochemical machining and diffusion bonding. The objective of this paper is to introduce a...

A Manufacturing Process Design for Producing a Membrane-based Energy Recovery Ventilator with High Aspect Ratio Support Ribs

Creator:: Kawula, Steven P.
Abstract:: Heating, ventilation, and air conditioning systems represent nearly half of building energy usage in the United States. Recent building regulations requiring increased air turnover within buildings will result in even greater air conditioning usage. To alleviate these concerns, membrane-based heat-and-moisture exchangers known as energy recovery ventilators have been developed to...

Force Prediction in the Compression Sealing of an Ultra-thin Elastoviscoplastic Membrane

Creator:: McNeff, Patrick Scot
Abstract:: The objective of this paper is to demonstrate a method for mechanically characterizing a 25 μm thick elastoviscoplastic hemodialysis membrane and for quantifying the force required to use that membrane in compression sealing. First, methods are developed for mechanically characterizing the thin elastoviscoplastic membrane. Then, a finite element model is...

Application of buckling behavior to evaluate and control shape variation in high-temperature microlamination

Creator:: Wattanutchariya, Wassanai
Abstract:: The miniaturization of energy, chemical and biological systems for distributed and portable applications, known as process intensification, is realized by the enhancement in heat and mass transfer performance within high surface-to-volume ratio microchannels. Fabrication of devices for process intensification is achieved in part by microlamination techniques. These techniques consist of...

Determining the dimensional requirements of a reliable compression sealing method for use in microchannel hemodialysers

Creator:: Ward, Dustin K.
Abstract:: Almost 600,000 people in the United States were treated for End Stage Renal Disease in 2010. A majority of those people received hemodialysis from central medical facilities. It has been reported a better treatment option for these patients would be realized if the patients had more frequent hemodialysis treatments. A...

Development of nickel aluminide (NiAl) microchannel array devices for high-temperature applications

Creator:: Kanlayasiri, Kannachai
Abstract:: The miniaturization of Microtechnology-based Energy, Chemical and Biological Systems (MECS) is made possible by the use of high aspect ratio microchannel arrays to increase the surface-area-to-volume ratio of the flow conduits within the devices, resulting in an improvement in the heat and mass transfer performance of the devices. However, advantages...

Development of a passive micro-ball valve

Creator:: Wangwatcharakul, Worawut
Abstract:: A novel design, material, and fabrication method are presented to fabricate a passive micro-ball valve. Microvalves are critical components in microflow control devices used to control the fluid flows in microchannels. These microflow control devices can be integrated with microsensors to form micro analysis systems. Glass/silicon-based fabrication is complicated and...
