Abstract

A method for manufacturing a plurality of components, each of the plurality of components including at least one electrical feedthrough, in which a functional element is fastened in a feedthrough opening in a base body by way of an electrically insulating material, an information being acquired in association with each of the plurality of components, the method comprising the steps of: providing, in one of a plurality of manufacturing steps of the method, each of the plurality of components or one of a plurality of pre-stages of each of the plurality of components with an information store, at least one of (i) the information being stored in the information store, and (ii) an identifier is stored in the information store and the information is stored in a database in association with the identifier.

First claim

What is claimed is:

1. A method for manufacturing a plurality of components, each of the plurality of components including at least one electrical feedthrough, in which a functional element is fastened in a feedthrough opening in a base body by way of an electrically insulating material, the method comprising the steps of:
acquiring information associated with each of the plurality of components; and
providing each of the plurality of components or one of a plurality of pre-stages of each of the plurality of components with an information store, at least one of (i) the information being stored in the information store, and (ii) an identifier being stored in the information store and the information being stored in a database in association with the identifier, wherein each of the plurality of components or a respective one of the plurality of pre-stages of each of the plurality of components is uniquely identified in at least one of a plurality of manufacturing steps via a position of each of the plurality of components or the respective one of the plurality of pre-stages in a component carrier and via a component carrier identifier that is assigned to the component carrier and uniquely identifies the component carrier.

2. The method according to claim 1 , wherein the information is selected as one or more from a group including: an information relating to a plurality of starting materials used; an information relating to the plurality of manufacturing steps which are carried out; an information relating to a plurality of tools and a plurality of installations used; an information relating to a plurality of measurements and a unique identifier.

3. The method according to claim 1 , wherein each of the plurality of components or a respective one of the plurality of pre-stages of each of the plurality of components is uniquely identified by reading the information store.

4. The method according to claim 1 , wherein a random sample of the plurality of components or each of the plurality of components is subjected to a final inspection, in which at least one property of a respective one of the plurality of components is measured, and a plurality of results of the final inspection are assigned to the respective one of the plurality of components as information.

5. The method according to claim 4 , wherein the plurality of results obtained in the final inspection are compared with a plurality of predefined setpoint values, and respective ones of the plurality of components that exceed at least one predefined limit value are ascertained.

6. The method according to claim 5 , wherein the respective ones of the plurality of components that are so ascertained to have exceeded the at least one limit value are referred to as a plurality of ascertained components, an assigned information of the plurality of ascertained components is evaluated, and, with respect to the plurality of ascertained components, a common information is determined as to which of the plurality of ascertained components are identical to or match within a predefined tolerance.

7. The method according to claim 6 , wherein at least one of the plurality of manufacturing steps, a plurality of starting materials, a plurality of tools, and a plurality of process conditions that the plurality of ascertained components have in common are ascertained from the common information, and in accordance therewith a plurality of quality improvement measures for a plurality of future runs of the method are initiated, wherein the plurality of quality improvement measures are selected from the following: an exchange of a tool; an exchange of a component carrier; an exchange or a calibration of a measuring device; a correction of a plurality of process parameters; a selection of other ones of a plurality of starting materials; and a plurality of combinations of the plurality of quality improvement measures.

8. The method according to claim 1 , wherein the information that is identical for a multiplicity of the plurality of components is stored only once in the database as a group information, and a respective reference to the group information is assigned to a respective one of the plurality of components.

9. The method according to claim 1 , wherein the information store is designed as an optically readable marker.

10. The method according to claim 9 , wherein the optically readable marker is formed on the functional element.

11. The method according to claim 10 , wherein the optically readable marker is obtained using a laser material machining method.

12. The method according to claim 1 , wherein a device is provided for manufacturing the plurality of components, the device including a machining mechanism configured for providing the plurality of components with an information store, the device being configured for carrying out the method for manufacturing the plurality of components.
