A method for fabricating a metallic timepiece component, wherein the method includes the steps of forming, via a UV-LIGA type process combined with hot stamping, a multi-level photosensitive resin mould and electroplating a layer of at least one metal from at least two conductive layers to form a block that substantially reaches the upper surface of the photosensitive resin.

Method of fabricating a timepiece component and component obtained from this method

A method for manufacturing metal horological components, includes the steps of forming a multilevel mould made of a photosensitive resin, with a UV-LIGA method, and galvanically depositing a layer of at least one metal starting from a conductive layer in order to form a block that substantially reaches the upper surface of the photosensitive resin.

A method for manufacturing metallic horological components includes the steps of forming a LIGA-UV type method a multi-level photosensitive resin mould and of galvanically depositing a layer of at least one metal using at least two conductive layers to form a block substantially reaching the top surface of the photosensitive resin.

Method for manufacturing a horological component and component obtained according to this method

The present invention relates to a method for manufacturing metal timepiece components, characterised in that it comprises the steps of forming a multi-level photoresist mould, by means of a UV-LIGA type method, and of galvanically depositing a layer of at least one metal starting from at least two conductive layers so as to form a block that substantially reaches the top surface of the photoresist.

Method for manufacturing a timepiece component and component obtained by this method

The invention concerns the field of micromechanical parts, in particular, for timepiece movements. The invention relates to a method of fabricating a mold that includes the following steps: (a) providing a substrate that has a top layer and a bottom layer made of electrically conductive, micromachinable material, and secured to each other by an electrically insulating, intermediate layer; (b) etching at least one pattern in the top layer as far as the intermediate layer to form at least one cavity in the mold; (c) coating the top part of the substrate with an electrically insulating coating; and (d) directionally etching the coating and the intermediate layer to limit the presence thereof exclusively at each vertical wall formed in the top layer.
