Problems solved by technology

But this fabrication technique is slow and complicated because there are strips of polymer material onto which strips of nanocrystals are bonded, so each strip must be etched before the different strips can be layered together to create the desired dimensions. element

Embodiment Construction

[0035] The principle of the invention is to manufacture parts for passive electronic components, especially magnetic passive electronic components, such as inductors or magnetic cores, by cutting by means of sandblasting from alternating stacks of brittle metal strips and hard and brittle adhesive Made of laminated strips composed of layers of material. Fragile metallic materials are magnetic and suitable for making magnetic electronic components. Such materials are especially nanocrystalline materials of the Fe—Cu—Nb—B—Si type or Fe—Zr—B—Si type, for example. Materials of this type are described, for example, in European patent EP0271657 or in European patent EP0299498. It is already known to produce such nanocrystalline materials by heat-treating amorphous strips produced by the ultrafast solidification of liquid metal alloys. Thin strips of this type have a thickness between a few micrometers and several tens of micrometers, especially between 5 and 50 micrometers, usuall...

Abstract

The invention relates to a method for production of pieces for passive electronic components in which: a layered strip (1) is produced, made from at least one stack of a thin metal strip and a layer of adhesive material, at least one piece (6) is cut from the layered strip (1), the cutting being carried out by a method including at least one etching step with sand. The invention further relates to the pieces obtained.

Description

technical field [0001] The invention relates to a method for the manufacture of parts for passive electronic components by cutting from a laminated strip consisting of a stack of thin and brittle metal strips, especially thin metal strips of nanocrystalline alloys into. Background technique [0002] Nanocrystalline alloys are known, especially of the Fe, Cu, Nb, B, Si type or of the Fe, Zr, B, Si type or other types. These alloys with exceptional magnetic properties are produced by heat-treating strips of amorphous alloys formed by the ultrafast solidification of liquid metals. While these strips are particularly suitable for producing magnetic cores with very high magnetic permeability, especially at low frequencies, they have the disadvantage of being particularly brittle. Therefore, in order to make magnetic cores from these nanocrystalline strips, it has been proposed to roll amorphous alloy strips to form rolls and then to perform heat treatment operations on these ro...
