Process Capability Study in Electronic Industry- Case Study on Aircoil Lead Frame Welding (HM72B-06XXX)

The aim of this project is to implement the industrial engineering tools in selected manufacturing company to identify the process capability at the company production lines and to improve the quality of the product of company. The chosen company is B.I Technology Sdn. Bhd. and the product being analyzed is molded inductor. The capability data were obtained from B.I Technology and further analysis on the data was done manually and by using MINITAB software. The process of understanding the control and the capability (PUCC) is an iterative closed loop process for continuous improvement. It covers the DMAIC toolkit in the three phases. PUCC is an iterative approach that rotates between the three pillars of the process of understanding, process control, and process capability. The objective of the six sigma study of Molded Inductance is to achieve perfection molded manufacturing by reviewing the present robust manufacturing process, to find out way to improve and modify the process, which will yield molded inductance that are defect free and will give more customer satisfaction. The application of six sigma led to an improved process capability. At the end of this project the result is the Cpk had being improved from 0.84 to 1.75.

The aim of this project is to implement the industrial engineering tools in selected manufacturing company to identify the process capability at the company production lines and to improve the quality of the product of company.

Growth Optimization of N-fixer, Isolated from Biofertilizer

The objectives of this experiment were to obtain the optimum temperature, pH and the requirement of carbon sources needed for the growth of N-Fixer bacteria. This research can be divided into two parts which are the standard curve preparation followed by optimization of the experiments. Three standard curves needs to be constructed; growth, glucose and CFU curves. These three curves will be used in optimizing the growth condition of N-fixer. Set of experimental works were designed by DOE software using full factorial function. Based on the experiment results, it shows that the optimum pH and temperature for the growth of N-Fixer is at pH 6 and 30°C respectively. As for the requirement of carbon sources, 10 g/L was applicable to avoid the surplus glucose become toxic to microorganisms. As the conclusion, the concentration of glucose plays a major role in the fermentation process (18 hours) either to increase the number of N-fixer cell or to decrease it. Therefore, by maintaining it at 10g/L the number of cell can achieve the upper limit to where it can be produced which is about 1.6834E8 cell/mL .

The objectives of this experiment were to obtain the optimum temperature, pH and the requirement of carbon sources needed for the growth of N-Fixer bacteria.

Zirconia Powder from Amang

The processing of amang in the laboratory has yield zircon with a purity extending to almost 100%. Based on the minerals identified in the amang several selected instrument were used to upgrade zircon concentration. The dissociation of alkaline oxide process was used to produce zirconia, and the results were compared with several other sources of zircon sand. [Authors' abstract].
