My active participation in these projects with manufacturing industry such as projects with Foxconn really help me to apply the knowledge to solve the problem. This experience attests to my determination to pursue this career. The analysis results of connector improvement project with Foxconn confirmed the ability of my analysis not only to propose the feasible solutions to improve the force performance of connector, but also generate practical evaluations for the cost in the manufacturing phase. These projects allowed me to apply theoretical concepts in a practical context and to develop my problem-solving skills.
