Problems solved by technology

[0005] The disadvantage here is that the small flag (which consists of the same film material as the back-molded film) protrudes from the finished body and can be easily damaged or can be torn off
Furthermore, the film material is tensioned during the injection molding process and this can lead to changes in the film material so that it loses its stability and elasticity and thus contributes to the above-mentioned possibility of damage

Embodiment Construction

[0047] All features disclosed in the application documents are claimed as being of inventive value to the invention insofar as they are novel individually and / or in combination with respect to the prior art.

[0048] in about Figure 1 to Figure 6 In the description of the drawings, the same reference numerals are used for the same elements. This serves for a better understanding of the drawing description and its clarity. Reference signs are used in the corresponding figures only if they are meaningful for the description of the invention in connection with the corresponding figure.

Abstract

The method according to the invention specifies the production steps of an electrical assembly which consists of at least one electrical component which is arranged on a film. The at least one electrical component is arranged on the film, which preferably consists of plastic. In addition, electrical conductor tracks are present on the foil, which connects the at least one electrical component to a connecting region with electrical contact points. Via these contact points and conductor tracks, the necessary electrical energy can be supplied to the electrical component for operation. In addition, input and output signals can be fed and discharged. The electrical component is, for example, For example a display, an operating element or a keyboard with corresponding keys.

Description

technical field [0001] The invention relates to a method for producing an electronic component with the features of claim 1 and an electronic component with the features of claim 18 . [0002] The electronic component according to the invention comprises a film and an electrical or electronic component arranged on or in the film, which is overmolded in an injection molding tool, in particular a plastic injection molding tool. The method includes method steps for producing an electrical component. Background technique [0003] Methods for back-injecting films are already known under the names "in-mold", "in-mold decoration" and "in-mold labelling". In "in-mold labeling", a film is introduced into an injection mold and then back-molded, and the entire film becomes an integral part of the injected body or plastic part. In "in-mold decoration", the so-called roll-to-roll method is used, in which a film strip is guided through the injection mold. The film tape has a carrier la...
