1. Jhuang, Yun-Da. Effect of Coated Material on Cu Wire Bonding in IC Package.

Degree: Master, Mechanical and Electro-Mechanical Engineering, 2012, NSYSU

Wire bonding has been used in integrated circuit packaging for many decades because of its high reliability and performance. The most common metal used has been gold, but with the surge in commodity prices of gold in recent years, copper wire is now used to altered gold wire for cost saving. Many challenges have to be solved to meet its application requirement; coating is one of the applications. In this study, a 3D coated copper wire and coated Al pad is built by finite element method to simulate ultrasonic bonding and thermosonic bonding. To consider the effect of coated material to stress and strain field on ultrasonic bonding and the effect of coated material to temperature field on thermosonic bonding. Then use the Taguchi experiment method to discuss the effect on Cu-Ball and Al pad under different coated material and thickness combination. The results show that with coated material on Al pad or copper wire could reduce more than 48% of effective plastic strain after the bonding process, it obviously reduce the Al splash phenomenon in copper wire bonding. But the coated material such like palladium and nickel which have lower thermal conductivity would resist the heat transfer. And the Taguchi experiment method shows that the most effective way to reduce the effective stress during impact stage and ultrasonic vibration stage is to increase the thickness of palladium and nickel respectively, and when the thickness of coated material Au reached 0.01μm could increase the temperature of Cu-Ball and Al pad mostly.

2. Alharthi, Adel Aifan. An integration of Lean Six Sigma and health and safety management system in Saudi Broadcasting Corporation.

Degree: PhD, 2015, Brunel University

Lean Six Sigma is a method used to improve the quality and efficiency of processes by reducing variation and eliminating wastes (non-value added activities) in an organisation. The concept of combining the principles and tools of Lean Enterprise and Six Sigma has been discussed in the literature. The majority of Lean Six Sigma applications in private industry have focused primarily on manufacturing applications. The literature has not provided a framework for implementing Lean Six Sigma programmes in non-manufacturing or transactional processes like those in the Entertainment Media industry. The Saudi Broadcasting Corporation (SBC), like many other industries in Saudi Arabia, has high occupational safety risks, such as electric, fire and fall hazards which often occur in the media workplace. These risks are considered very costly and affect productivity and employee morale in general. The main objective of this research is to provide a synergistic approach to integrating occupational health and safety programmes and Lean Six Sigma tools using the DMAIC (Define-Measure-Analyse-Improve-Control) problem-solving method to strengthen and assure the success of safety programmes in the Saudi Broadcasting Corporation (SBC). This research identifies the roadmap (i.e. activities, principles, tools, and important component factors) for applying Lean Six Sigma tools in the media industry. A case study addressing the safety issues that affect employees’ performance within the Saudi Broadcasting Corporation (SBC) TV studio is used to validate work outlined in this research. Furthermore, the Bayesian Belief Networks (BBN) method is used to understand the probability occurrence of safety hazards. The application of the Taguchi Experimental Design method and other Lean Six Sigma tools, such as Cause and Effect diagrams, Pareto principles, 5S, Value Stream map, and Poka-Yoke have been incorporated in to this research. The application of Lean Six Sigma DMAIC problem-solving tools resulted in significant improvement in safety within SBC. The average electrical hazard incident decreased from 2.08 to 0.33, the average fire hazard incident decreased from 1.25 to 0.08, and the average fall hazard incident decreased from 3.42 to 0.17. The research has important implications for the company and its employees, with positive outcomes and feedback reported by top management, the senior technicians, and experts. The research improved the safety by reducing electrical, fire and fall risks. The Safety training sessions are one of the most significant factors that improve their safety awareness. It is observed that Lean Six Sigma problem-solving tools and methods are effective in the Saudi Broadcasting Corporation (SBC).

3. Boscolo, Marco. Optimization of inversion ankle taping: a Taguchi method based study.

Degree: PhD, 0351, 2013, University of Illinois – Urbana-Champaign

Optimization of a complex process or system is often a task utilized in industrial engineering where specialized Designs of Experiments (DOEs) are used. Optimization for the purpose of finding the ideal condition of a product or process is a novel concept in kinesiology. In kinesiology research comparing 3 or more multi-level independent variables (IVs) is rarely conducted. In optimization DOE studies, each IV is a multi-level independent variable and all combinations of these variables are studied simultaneously with a factorial DOE approach or method. One such method is the Taguchi Method (TM), which is a robust industrial engineering optimization DOE method developed by Dr. Genichi Taguchi in post WWII Japan. The TM was created for the purpose of developing a product or process in a cost effective and efficient manner. To conserve resources the TM relies on fractional factorial orthogonal arrays, which require half or less of all possible linear combinations (LC). The TM works best when the materials under study behave uniformly. When the material behaves uniformly only a few replications of a LC are needed. In optimization studies with humans, humans are the material, and often humans behave non-uniformly which requires many repeat observations of LCs to achieve stable results. The purpose of this study was to validate the use of the TM in a kinesiology and athletic training application using humans along with determining what sample size produces consistent results in a TM study. For this study, the reduction in ankle inversion motion was studied by manipulating ankle taping variables relating to how thick the tape was applied, how high up the lower leg tape was applied, and how thick the prewrap was applied. Each independent variable (IV) was studied at two levels using the same ankle taping pattern. A TM orthogonal linear array four (L4) and a full factorial array were compared to see how close the two arrays optimal results were in value. For score stability progressively smaller sample sizes were analyzed. Video and inclinometery based motion analyses were used to measure the amount of ankle inversion motion, and the amount of plantar flexion. In addition, the weight of each participant’s ankle taping for each LC was measured for cost comparison. No TM based environmental variables where used in this study. Repeated measures statistical analysis was used which involved each participant being tested in each of the taping LCs, a no tape condition, and a durable ankle brace condition. The participants had no history of ankle injury in the past 12 months. The results of this study showed the TM identifying the same optimal LC parameters as the full factorial approach. The results also showed that the TM’s estimated optimal condition value was consistent with the optimal value found with the full factorial approach. To achieve statically significant results a sample size of n = 34 was needed in this study, but if the main emphasis of the researcher was in identifying meaningful difference between LC for… Advisors/Committee Members: Zhu, Weimo (advisor), Zhu, Weimo (Committee Chair), Iwamoto, Gary (committee member), Sosnoff, Jacob J.
