Manufacturing techniques are described for forming electrical components. For example, a layer of a metal powder composition is deposited onto at least a portion of a substrate. Pressure is applied to the metal powder composition by hydraulic press that has one or more projections in order to capture a pattern on the substrate. The metal powder composition compressed by the projections of the hydraulic press adhere to the substrate to form the captured pattern. The metal powder composition in regions not compressed by the projections of hydraulic press do not adhere to the substrate and may be removed. The metal powder composition may be compressed to form electrical components, such as antennae, capacitor plates, conduction pads and the like, for use in an electronic surveillance system (EAS), a radio frequency identification (RFID) system, or the like.

L'invention concerne des techniques de fabrication en vue de la formation de composants électriques. Par exemple une couche d'une composition de poudre métallique est déposée sur au moins une partie d'un substrat. On applique une pression sur la composition de poudre métallique par pression hydraulique ayant une ou plusieurs protubérances de manière à capturer un motif sur le substrat. La composition de poudre métallique comprimée par les protubérances de la pression hydraulique adhère au substrat afin de former un motif capturé. La composition de poudre métallique dans les zones non comprimées par les protubérances de la pression hydraulique n'adhère pas au substrat et peut, par conséquent, être retirée. La composition de poudre métallique peut être comprimée pour former des composants électriques, notamment des antennes, des plaques de condensateur, des coussinets de conduction et analogues, en vue d'une utilisation dans un système de surveillance électronique (EAS), un système d'identification radio fréquence (RFID) ou analogue.
