Abstract

A process for producing a component module comprising a module carrier and a plurality of components with which contact is made on the latter, comprising the following steps: arranging separated components on a surface-adhesive film at a predefined contact-specific spacing from one another, embedding the components in a flexible material in order to form a flexible holding frame which holds the components, pulling off the film, producing contact-making elements on the exposed side of the components, performing a functional test of the components and, if necessary, repair and/or replacement of components, and fixing and making contact with the components held in the holding frame on the module carrier.

Claims (17)

1. A method for producing a component module comprising a module carrier and a plurality of components with which contact is made on the latter, the method comprisings:

(a) arranging separated components on a surface-adhesive film at a predefined contact-specific spacing from one another;

(b) embedding the components in a flexible material in order to form a flexible holding frame which holds the components, the flexible holding frame providing a pocket-like holder for each of the components embedded in the flexible holding frame and the flexible material having a pliability so that the flexible holding frame can be bent to remove an individual component of the components embedded in the flexible holding frame from its pocket-like holder;

(c) pulling off the film;

(d) producing contact-making elements on the exposed side of the components;

(e) determining which of the components embedded in the flexible holding frame is a non-functional component by performing a functional test of the components;

(f) removing the non-functional component from its pocket-like holder by bending the flexible holding frame so that the flexible holding frame opens in an area where the flexible holding frame encloses the non-functional component;

(g) repairing the non-functional component and inserting the repaired component in the relevant pocket-like holder, or inserting a new component in the pocket-like holder of the removed non-functional components; and

(h) fixing and making contact with the components held in the holding frame on the module carrier.

2. The method as claimed in claim 1 , wherein the components used are both active and passive components.

3. The method as claimed in claim 1 , wherein the film used is a double-sided adhesive film, which is firstly bonded to one or more module carriers, after which the components are bonded to the film on the basis of their associated contact-making positions on the module carrier, which determine the contact-specific spacing, and after which the film is pulled off from the module carrier or carriers.

4. The method as claimed in claim 1 , wherein only components tested as serviceable in a preceding functional test are bonded to the film.

5. The method as claimed in claim 1 , wherein the components are potted or printed with the material in order to embed them.

6. The method as claimed in claim 1 , wherein the material used is silicone.

7. The method as claimed in claim 1 , wherein the contact elements and, if appropriate, cross-wiring are produced outside the silicon, on the flexible holding frame.

8. The method as claimed in claim 1 , wherein, in order to fix and make contact with the components at the contact-making positions on the module carrier, contact-making elements are produced.

9. The method as claimed in claim 1 , wherein, in the event of integration of components for a plurality of module carriers in a common holding frame, the holding frame is divided up, before or after the performance of the functional tests, in order to form module-specific frame sections.
