Problems solved by technology

[0014] This type of method has the disadvantage of only allowing the production of silicon components and not of silicon oxide, known under the name Silinvar (registered trademark), which allows thermal compensation
Furthermore, this type of method has disadvantages caused by photolithographic methods in addition to the fact that it has a high risk of contamination of the DRIE etch chamber

Embodiment Construction

[0056] refer to Figure 1A to Figure 1D , the method for producing the timekeeping component comprises for producing the first part 1 by microfabrication or micromolding methods known to those skilled in the art, for example by a first material such as silicon (cf. Figure 1A ) of the first step. The first material may consist of any other material such as metal, ceramic, plastic, diamond, quartz, glass, silicon carbide or combinations thereof. Furthermore, said first part is composed of any chronograph component known to those skilled in the art, such as escape wheels, balance wheels, etc.

[0057] In the second step, refer to Figure 1B , depositing the second material 2 on the first part 1, on all or a part of the first part 1, and then refer to Figure 1C , processing steps are performed on the second material to connect the components of the second part 3 to each other and to connect the second part 3 to the first part 1 and form the porous second part 3 . It will be n...

Abstract

The present invention relates to a method for producing a timepiece comprising at least one first part produced by a microfabrication or microforming method in at least one first material, the methodcomprising at least: a step of depositing, on the first part, without moulding, at least one second part of the timepiece in at least one second material, and a step of treating the second material inorder to connect together the components on the first part.

Description

technical field [0001] The invention relates to a method for manufacturing a timepiece and / or a set of timepieces and to a timepiece obtained according to said method. [0002] More specifically, the invention relates to a method of manufacturing a composite timekeeping component having two parts, namely a first part obtained from a first material, such as silicon, and a second part obtained from a second material, such as metal. the second part. Background technique [0003] In the field of watchmaking, it is well known to manufacture timekeeping components such as balance springs, wheels or balance wheels, for example from silicon. [0004] Indeed, silicon has many advantages, including its portability, its elasticity, its non-magnetic properties, and its ability to be processed using microfabrication techniques such as Deep Reactive Ion Etching (DRIE). [0005] However, silicon also has many disadvantages. For example, silicon is weak and brittle, and because it has no...
