Zusammenfassung:	A method for fabricating an electronic device or component such as an anisotropic conductive film comprising: distributing a plurality of conductive particles (112) into an array of microcavities (125) formed on a surface of a continuous carrier belt (190), rotating the belt carrying the conductive particles while conveying a surface of an adhesive layer (120) into contact with the surface of the rotating belt, transferring the conductive particles from the microcavities on the belt to the adhesive layer in predefined locations in the adhesive layer corresponding to the array of microcavities on the belt, and separating the adhesive layer from the surface of the belt. In one embodiment, the position of the microcavities is varied in a controlled manner. L'invention concerne un procédé pour fabriquer un dispositif ou un composant électronique tel qu'un film conducteur anisotrope comprenant: la distribution d'une pluralité de particules conductrices dans un réseau de microcavités formées sur une surface d'une bande transporteuse continue, l'entraînement en rotation de la bande transportant les particules conductrices tout en amenant une surface d'une couche adhésive en contact avec la surface de la bande rotative, le transfert des particules conductrices des microcavités de la bande à la couche adhésive dans des emplacements prédéfinis dans la couche adhésive correspondant au réseau de microcavités sur la bande, et la séparation de la couche adhésive de la surface de la bande. Dans un mode de réalisation, la position des microcavités varie de manière contrôlée.
