Un nouveau processus d'auto-alignement utilisant la tension superficielle de la résine liquide pour l'assemblage de dispositifs électroniques ou optoélectroniques dans un espace tridimensionnel a été proposé. L'alignement vertical peut être contrôlé à l'aide d'une sphère métallique, réduisant ainsi le contrôle précis nécessaire du processus, tel que les volumes de soudure et les forces externes, et permettant de grandes tolérances en matière de volume de liquide et de désalignement. L'alignement latéral pourrait également être obtenu en contraignant la résine liquide sur les plots tridimensionnels de la puce et du substrat. Cette étude s'est concentrée sur le principe de l'auto-alignement et de la précision de l'alignement final. De plus, la possibilité d’un processus d’auto-alignement a été vérifiée par une méthode analytique numérique et une expérience à plus grande échelle. Une précision d’alignement moyenne inférieure à 3 µm a été obtenue. On pense que ce procédé est efficace pour un assemblage simplement à basse température, à faible coût et sans flux dans les futures techniques d'assemblage.

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.
