碩士 === 國立高雄應用科技大學 === 機械與精密工程研究所 === 103 === This study examines the micro stamping using only the upper and lower die,when the influence of tool shape and die gap and material thickness and other factors, the material sheet quality how to choose to make punchingout the best, and discussed the influence of factors on micro stamping is the largest. When the mold gap more and more hours to do out of the mold, high accuracy and have good contraposition precision machine and its cost is very high, does not meet the commercial interests, so the discussion when there are underlying material instead of the lower die, can achieve its ownmaterial piece of good quality, if the material thickness, strength andcushion the lower pad thickness changes on micro stamping results with what effect. The characteristics of this study is micro stamping experiment using only theupper die, lower die using the underlying deformation forming, punchingsheet to achieve the effect of. Micro stamping die is used for photolithography process will be made into KMPR thick photoresistphotoresist mold, sent to the electroformed nickel cobalt alloy, and finally demoulding to obtain micro stamping tool. This study uses the DEFORM finite element software to simulate micropunch pressing process of deformation and forming load force, first by using the 2D software simulation using only the upper and lower diestamping simulation, again following pads replaced the lower die stamping,finally carried on the 3D simulation analysis, to explore the effect ofchanging the shape of tool for micro stamping. The use of edge width 15 m three and six selection cutting tool stampingthree PET material thickness and three kinds of aluminum foil in this studyto investigate the underlying thickness, when the material thickness changeand foil underlying changes, what is the impact on stamping, and the simulation analysis and experimental verification. This study examines when changing the micro stamping tool shape, whether can increase its stamping life, in order to reduce the cost of.
