| 摘要: |
| 目的 研究丝网印刷过程中刮胶角度、刮胶速度、离网间距、刮胶压力对印刷品质量的影响规律，为丝网印刷电子的实际应用提供技术参考。方法 利用现有丝网印刷试验台，对4个印刷参数进行正交试验；运用偏最小二乘法对实验中的数据进行影响因素主次判断。结果 离网间距对印刷电子中导电线条宽度和导电线条表面粗糙度的影响最为明显，刮胶压力、刮胶角度和刮胶速度在确定范围内对导电线条表面粗糙度和宽度的影响并不明显；经由正交试验分析出丝网印刷的最优工艺条件为C3A1D1B3。 结论 通过偏最小二乘法对实验数据进行分析，验证了正交试验的合理性；在丝网印刷电子印制过程中，正确选用合理的离网间距是获得高品质印品的关键。 |

| Abstract: |
| The work aims to study the law of effects of squeegee angle, squeegee speed, off-grid spacing and squeegee pressure on the quality of printed products during screen printing, so as to provide technical reference for the practical application of screen printing electronics. The orthogonal test was carried out on the four printing parameters with the existing screen printing test bench. The partial least squares method was used for the primary and secondary judgment on the influencing factors of the data in the experiment. The off-grid spacing had the most obvious influence on the width and surface roughness of the conductive lines in the printed electronics. The effect of the squeegee pressure, the squeegee angle and the squeegee speed on the surface roughness of conductive lines was not obvious. Based on the orthogonal test analysis, the best technological condition for screen printing was C3A1D1B3. The experimental data were analyzed by partial least squares method to verify the rationality of the orthogonal test. In the screen printing electronic printing process, the correct selection of reasonable off-grid spacing is the key to obtain high quality printed products. |
