Abstract

De manière classique, un transfert hydraulique a été utilisé pour un transfert vers un objet tridimensionnel; cependant, avec ce procédé, il n'était pas possible de commander la déformation d'image, d'obtenir un positionnement précis ou d'assurer un bon environnement de travail. La mesure dans laquelle le transfert hydraulique peut être appliqué à des circuits conducteurs était également limitée. Une encre adhésive de transfert avec laquelle il est possible d'obtenir un film durci hybride de silice à l'aide d'une feuille de transfert d'eau a eu des applications limitées car une telle encre adhésive de transfert ne peut pas être transférée à un objet tridimensionnel, par exemple. La présente invention résout les problèmes liés au transfert hydraulique en formant une couche adhésive avec l'encre adhésive comme alternative à un traitement d'activation et un transfert pneumatique supplémentaire est rendu possible par humidification d'un film de résine de PVA. De plus, en combinaison avec une variété de supports de transfert, la présente invention permet un transfert à grande vitesse ou une impression de réserve, un transfert de circuit avec un changement dimensionnel minimal et un transfert vers un objet tridimensionnel.
