市調公司IDTechEx 預測，印刷電子市場在未來十年將可增長到超過 500 億
美元的規模，其中太陽光電、顯示技術和邏輯應用所占比率最大。雖然革命性的
印刷電子技術仍處於起步階段，但它的潛在影響力卻是相當大的，從低成本
solution-processed 薄膜太陽能以及OLED 照明，甚至到電子紙顯示器和薄膜電
池等產品都是在其領域中。因此，高強度的不鏽鋼細線則被視為影響電子印刷品
質的重要關鍵材料，在生產小於30μm 的不銹鋼線且抗拉強度大於3200Mpa，全
世界的技術皆控制在日本的公司中，因此對於生產此關鍵性的不銹鋼線則是台灣
所缺少的技術之一。從相關研究中，極細線伸線的過程中其介在物一直是影響生
產的重要因素，由於介在物在伸線變形過程中的行為模式是複雜的，因此研究介
在物塑性變形的行為就顯得非常重要。本研究中冺用了有限元素與反應曲面的方
法來找出伸線製程與鑽石眼模的改變以找出能減少介在物對於斷線機率與提高不
銹鋼細線強度的影響因素並找出重要的生產技術。在本研究的結論中發現減少介
在物在塑性變形過程中的旋轉角度與降低伸線方向垂直的壓力是影響伸線過程中
的斷線機率與提高不銹鋼細線強度的重要因素。本研究所得到的生產條件，介在
物的直徑大於線徑的面積60%時對於不銹鋼細線機械性質仍保持一定的強度，因
此冺用此結果所生產的不銹鋼細線的強度能提高6%，且大幅降低伸線過程中的斷
線機率。

According to the market research company IDTechEx predicts the printed electronics
market in the next decade will grow to over 50 billion US dollars of the market, where
accounted for the largest proportion with solar photovoltaic, display technology of
application logic. Although revolutionary printed electronics technology is still in the
growth stage, but its potential to influence is quite large, from the low-cost
solution-processed with thin-film solar and OLED lighting, even to the e-paper
displays. The fine stainless wire less than 30um is considered the key factor that affects
the manufacturing quality of printing electronics. However, the production technology
of the fine stainless wire is currently dominated by Japanese manufacturers.
Developing this production technology of 30um fine stainless wire becomes critical in
Taiwan’s manufacturers. In previous researches, non-metallic inclusion has been an
important factor affecting the efficiency of the fine wire production. It is essential to
study the deforming behavior of non-metallic inclusion in the fine wire production
process. The study uses simulation and response surface methods to find the
parameters of production process and diamond dies so as to reduce the impact of
inclusion to the wiring process including reducing wire breakage and increasing wire
strength. The result shows that using the parameters found in this research, when the
inclusion’s diameter is larger than 60% of the diameter of wire’s cross-section,
mechanical properties still maintain a good intensity. The intensity of fine wire can be
increased by 6%, and the wire breakage is significantly lower than before.
