Due to the rapid development of precision micro-manufacturing technology, the connection and assembly process of precision micro devices put forward higher requirements for the volume and accuracy of micro dispensing technology. In this paper, an ultra-micro dispensing method based on the surface tension is proposed. It can realize micro size feature adhesive dispensing, here, adhesive droplet volume is in range of fL—pL. The transferring needle passes through the thin tube filled with adhesive liquid, and correspondingly, a micro amount of adhesive liquid is attached to the needle depending on the adhesion between needle and liquid. Then, the adhesive force between adhesive liquid and dispensing surface and the liquid’s self surface tension make a micro amount of adhesive liquid left on the dispensing surface and form a droplet. In this paper, we carried out a set of detailed single factor experimental study, and systematically analyzed the affection of main working parameters,...

基于表面张力的用于微细加工的超微精密点胶方法及其关键影响因素分析

由于精密微制造技术的飞速发展，精密微设备的连接和组装过程对微点胶技术的体积和精度提出了更高的要求。本文提出了一种基于表面张力的超微点胶方法。它可以实现微细尺寸特征的点胶，这里的点胶量在fL-pL范围内。输送针穿过填充有粘合剂液体的细管，并且相应地，取决于针与液体之间的粘附力，微量的粘合剂液体附着到针上。然后，粘合剂液体与分配表面之间的粘附力以及液体的自身表面张力使微量的粘合剂液体残留在分配表面上并形成液滴。在本文中，
