碩士 === 國立臺北科技大學 === 機電整合研究所 === 95 === Life test for cell-phone is to examine whether a flexible printed circuitry board and mechanisms of hinge conform to the specification standard or not by repeated opening and closing operation of cell-phone. It is an important test programs for the cell-phone manufacturer. Therefore, this thesis focuses on developing and designing a testing machine for the life test of the flip cover in a flip phone. The research processes are to collect the literatures and data regarding life test machines used by industries, to evaluate those data and select the appropriate mechanisms thorough Analytic Hierarchy Process to design the model and to perform the stress analysis and fatigue life. Finally, prototype is built and tested. The prototype developed has the features of easy adjust meat for different sizes of cell-phone and friendly user interface.
