Abstract

A method for producing an electronic device, the method including: encasing an electronic assembly with a first casing material; holding the first electronic assembly encased by the first casing material over a holding element such that the holding element is spaced apart from the electronic assembly above the first casing material, and encasing the assembly retained on the holding element with a second casing material.

First claim

The invention claimed is:

1. A method for producing an electronic device, comprising:
encasing an electronic assembly with a first casing material,
forming a tight fit receiving element on the first casing material, the receiving element adapted to receive a holding element in a positive manner;
holding the electronic assembly encased by the first casing material by the holding element in such a manner that the holding element is spaced apart from the electronic assembly above the first casing material, and
encasing the assembly held on the holding element with a second casing material, the encasing including encasing the holding element within the receiving element such that the holding element becomes integral with the electronic assembly.

2. The method as claimed in claim 1 , comprising:
forming a tight fit element called labyrinth element on the first casing material, which after the encasing by the second casing material forms a labyrinth gap between the first casing material and the second casing material.

3. The method as claimed in claim 2 , wherein the labyrinth element is configured to run around a holding region, in which the holding element for holding the electronic assembly encased by the first casing material is set.

4. The method as claimed in claim 1 , wherein the first casing material and the second casing material are configured in such a manner that during the encasing of the first casing material, the second casing material fuses this in certain regions.

5. The method as claimed in claim 4 , comprising forming a melting rib on the first casing material, which is fused in certain regions during encasing by the second casing material.

6. The method as claimed in claim 4 , wherein after encasing the electronic assembly by the first casing material, the holding element is introduced into the receiving element.

7. The method as claimed in claim 1 , wherein the electronic assembly has an electrical connection for electrical contacting, on which the electronic assembly is held during encasing by the first casing material and/or by the second casing material.

8. The method as claimed in claim 1 , comprising:
arranging a fastening element next to the electronic assembly encased by the first casing material, and
encasing the electronic assembly encased by the first casing material and the fastening element by the second casing material.

9. A method for producing an electronic device, comprising:
encasing an electronic assembly with a first casing material,
forming a receiving element on the first casing material, which is adapted to at least positively receive the holding element, wherein the holding element holds the first casing material in such a manner that the holding element is spaced apart from the electronic assembly above the first casing material, and
encasing the assembly held on the holding element with a second casing material, the encasing including encasing the holding element within the receiving element such that the holding element becomes integral with the electronic assembly.
