Abstract
L’invention se rapporte à un procédé de fabrication d’une pièce de micromécanique (31, 41, 61, 91) monobloc comportant au moins deux niveaux distincts. Selon l’invention, le procédé comporte un processus LIGA à un seul niveau combiné avec un usinage du dépôt LIGA directement sur le substrat (2). L’invention concerne en particulier le domaine des pièces de micromécanique horlogères.The invention relates to a method for manufacturing a one-piece micromechanical part (31, 41, 61, 91) comprising at least two distinct levels. According to the invention, the method comprises a single level LIGA process combined with machining of the LIGA deposit directly on the substrate (2). The invention relates in particular to the field of watchmaking micromechanical parts.
Description
DescriptionDescription
Domaine de l’invention [0001] L’invention se rapporte à un procédé de fabrication d’une pièce de micromécanique monobloc comportant au moins deux niveaux distincts.FIELD OF THE INVENTION The invention relates to a process for manufacturing a one-piece micromechanical part comprising at least two distinct levels.
Arrière-plan de l’invention [0002] Il est connu de former des pièces métalliques à plusieurs niveaux distincts à l’aide de procédé du type LIGA successifs, c’est-à-dire à partir de couches empilées comportant un moule structuré en résine et un métal dans les creux du moule déposé par galvanoplastie.BACKGROUND OF THE INVENTION It is known to form metal parts at several distinct levels using successive LIGA type processes, that is to say from stacked layers comprising a mold structured in resin and a metal in the hollow of the mold deposited by electroplating.
[0003] Toutefois, ces procédés successifs pour former plusieurs niveaux sont difficiles à mettre en œuvre car il est nécessaire de correctement référencer les niveaux entre eux. De plus, il est apparu que cette difficulté engendrait des coûts très supérieurs par rapport à deux dépôts galvaniques à un seul niveau.However, these successive methods for forming several levels are difficult to implement because it is necessary to correctly reference the levels between them. In addition, it appeared that this difficulty generated much higher costs compared to two galvanic deposits at one level.
