高粘度导电浆料微滴喷射成形导电线路表面质量研究
Surface quality of conductive line formed by micro-droplet jetting high viscosity conductive pulp
摘要
Abstract
In order to evaluate the surface quality of conductive line formed by impact-injection of high viscosity conductive pulp,the line horizontal profile accuracy and section profile roughness indicators are put forward.The horizontal profile quality and section profile quality model are established according to the droplet fusion characteristics.Conductive lines jet forming testes are carried out under different single droplet diameter and droplet spacing.The data of the average line width,peak-valley difference of horizontal profile and sectional profile height are obtained using methods of confocal laser microscope scanning and MATLAB image processing.The accuracy of horizontal profile and the roughness of section profile are calculated.The analysis results show that when the ratio of droplet spacing to droplet diameter is in the interval of(0,0.5],the line has the smaller fluctuation of horizontal profile;when the ratio is about 0.1,the line has the minimum fluctuation of sectional profile,and the quality of sectional profile decreases rapidly with the increase of the ratio.Therefore,in the process of impact-injection of high viscosity conductive pulp,set reasonable droplet spacing for different single droplet diameters can effectively improve the line surface morphology and the quality of conductive line jet forming.关键词
