Foi proposto um novo processo de auto-alinhamento utilizando a tensão superficial da resina líquida para montagem de dispositivos eletrônicos ou optoeletrônicos no espaço 3-D. O alinhamento vertical pode ser controlado através do uso de esfera metálica, reduzindo o controle preciso necessário do processo, como volumes de solda e forças externas, e permitindo grandes tolerâncias no volume de líquido e desalinhamento. O alinhamento lateral também poderia ser alcançado fazendo com que a resina líquida fosse restringida nas almofadas tridimensionais no chip e no substrato. Este estudo focou no princípio do auto-alinhamento e precisão do alinhamento final. Além disso, a possibilidade de processo de auto-alinhamento foi verificada por método numérico analítico e experimento ampliado. Foi obtida uma precisão média de alinhamento inferior a 3 µm. Pensa-se que este processo é eficaz para montagem simplesmente a baixa temperatura de processo, baixo custo e sem fluxo em futuras técnicas de montagem.

Abstract: A novel self-alignment process using the surface tension of the liquid resin for assembly of electronic or optoelectronic devices in 3-D space has been proposed. The vertical alignment can be controlled by using of metal sphere, reducing the necessary precise process control such as solder volumes and external forces, and allowing large tolerances in liquid volume and misalignment. Lateral alignment could be also achieved by making the liquid resin constrained on the 3-dimensional pads on chip and substrate. This study focused on the principle of self-alignment and final alignment accuracy. In addition, the possibility of self-alignment process was verified by analytic numerical method and scaled-up experiment. An average alignment accuracy of less than 0.25 µm has been obtained. It is thought that this process is effective for assembly simply at low process temperature, low cost and without flux in future assembly techniques.
