摘　　要：目的丝网印刷电子技术已被广泛应用于生物医疗、传感器及电子电路等领域,研究刮刀角度、离网间距、刮刀压力对印刷电路导电性能的影响,对提升工业生产过程中印刷电子产品的精确度和质量具有重要意义。方法利用丝网印刷设备和检测仪器对刮刀角度、离网间距、刮刀压力进行正交试验,探索最优工艺条件,并用多参数对比试验对正交试验结果进行验证。结果通过正交试验得到最佳方案为c_(2)a_(1)b_(2)或c_(2)b_(2)a_(1),由多参数对比试验得到以下结果:当离网间距为1.0 mm或1.4 mm,刮刀角度为60°,当刮刀压力等效间距为1.1mm时,对应线条阻值最小;当刮刀压力等效间距为1cm,离网间距为0.8mm时,线条不同位置阻值的波动范围最小。结论离网间距对印刷电路导电性能的影响最明显,其次是刮刀压力,最后是刮刀角度;试验结果验证了正交试验设计在研究印刷电路导电性能方面的可靠性,但在研究阻值稳定性方面存在些许不足。It is well known that screen printing electronic technology has been widely used in the fields of biomedical engineering,sensors,and electronic circuits.Investigating the effects of scraper angle,off-grid spacing,and blade pressure on the electrical conductivity of printed circuits is crucial for enhancing the accuracy and quality of printed electronic products in industrial production.Orthogonal experiments were conducted to investigate the effects of blade angle,off-grid distance,and blade pressure using screen printing equipment and testing instruments to determine the optimal process conditions for screen printing.Subsequently,these optimal conditions were validated through multi-parameter comparative experiments.The optimal solution obtained through orthogonal experiments was either c2a1b2 or c2b2a1.Results from multi-parameter comparative experiments indicated that the minimum line resistance value corresponded to an off-grid spacing of 1.0 mm or 1.4 mm,a blade angle of 60°,and an equivalent distance for blade pressure of 1.1 mm.Additionally,when the equivalent distance for blade pressure was set at 1.0 cm and the off-grid spacing at 0.8 mm,the fluctuation range of resistance values at different positions along the lines was minimized.The experimental results indicate that the most significant factor affecting the conductivity of printed circuit is the off-grid distance,followed by blade pressure and finally blade angle.The experimental results validate the reliability of orthogonal experimental design in studying the conductive performance of printed circuits.However,there are some shortcomings in its application to the investigation of resistance stability.
