摘要
在制成能力为70μm/70μm的设备上探索进行理论线间距为40μm/40μm的挠性板精细线路工艺研究过程中,用正交试验法的L9(34)正交表安排蚀刻速度、曝光能量和显影速度三因素试验。试验发现,显影速度对精细线路影响最大,其最佳工艺优化参数为A1B3C2,即蚀刻速度为5.5 m/min、显影速度为2.8 m/min和曝光能量为60 mj。
In this paper L9（34） orthogonal arrangement is used to take the orthogonal experiment which includes three factors.We take the device with theoretical production process is 70μm/70μm to produce single-sided flexible printed circuit board with line and space 40μm/40μm.The factors are etching speed,exposure energy and developing speed.The results of the experiment showed that developing speed is the factor which play the most important role during the fine line manufacturing and the best parameters are 5.5m/min of etching speed,2.8m/min of developing speed and 60mj of exposure energy.
