毛细力驱动自组装的定位是利用微元件及基片表面之间的毛细力作用实现的。为了研究微元件及组装区的形状对自组装定位的影响,在分析毛细力驱动自组装机理的基础上,利用能量法建立了毛细力驱动自组装系统的定位解析模型,预测了不同形状微元件的自组装结果,并对一些不合理的组装设计进行了修正。结果表明:通过计算自组装表面能量可以预测组装结果,并设计合理的粘合区形状。
Capillary-driven self-assembly of the positioning is the use of micro-components and substrate surface between the capillary force effect. In order to study the influence of shape of micro-component and assembly area on self-assembly orientation, based on the analysis of the self-assembly mechanism of capillary force drive, the position analysis model of capillary force driven self-assembly system was established by energy method. Self-assembly results, and some unreasonable assembly design was amended. The results show that the assembly results can be predicted by calculating the self-assembly surface energy and the shape of the adhesive zone is designed.
