本研究進行IC導線架橋帶（dam-bar）沖剪實驗，以SKH9與ASP60沖頭剪切C5191磷銅導線架材料，評估出導線剪切邊角的毛邊寬度、以及dam-bar剪切面品質之表現。此外，並利用最小平方法、指數平滑法、以及灰預測三種方法建立導線dam-bar剪切邊角毛邊寬度的預測模型。其中以灰預測模型的預測精度最為準確。
This study is successfully conducting the IC dam-bar trimming experiments. The tool materials of SKH9 and ASP-60 are used to perform the dam-bar cutting process of the phosphor bronze material (C5191). The burrs width of leads on the trimming edges, and shearing qualities of the shearing surface are inspected as the characteristics in the evaluation of experimental results. Furthermore, the prediction model of burrs width on the trimming edges of the leads is established. Three prediction methods establishing with least squares method, exponential smoothing method, and grey prediction method, are presented. The grey prediction mode obtains the best prediction accuracy.
