Abstract

A method for producing a composite window pane, particularly a motor vehicle windscreen, includes mounting guide pins and electronic components on traces of a printed circuit board and inserting the printed circuit board between a first and a second glass plate. The guide pins are inserted in passthroughs in the first glass plate.

First claim

What is claimed is:

1. A method for producing a composite window pane comprising: a) mounting guide pins and electronic components on traces of a printed circuit board; b) inserting the printed circuit board between a first glass plate and a second glass plate, wherein the guide pins are inserted in passthroughs in the first glass plate; and c) interposing a plastic composite layer between the printed circuit board and the second glass plate.

2. The method according to claim 1 , wherein the guide pins are metallic.

3. The method according to claim 2 , further comprising mounting the guide pins and the electronic components in a common soldering process.

4. The method according to claim 2 , further comprising positioning the guide pins on a solder pad on the printed circuit board while hot.

5. The method according to claim 1 , further comprising positioning the printed circuit board on the first glass plate and then covering the printed circuit board with the second glass plate.

6. The method according to claim 5 , further comprising inserting the guide pins in the passthroughs before a contact is created between the printed circuit board and the first glass plate, and spreading the printed circuit board over the first glass plate starting from the passthroughs.

7. The method according to claim 1 , further comprising covering the printed circuit board by the plastic composite layer.

8. The method according to claim 1 , further comprising filling cavities that remain after the guide pins have been inserted in the passthroughs.

9. The method according to claim 8 , further comprising filling the cavities with solder.

10. A composite window pane comprising: first and second glass plates, wherein the first glass plate has passthroughs formed therein; a plastic composite layer interposed between the printed circuit board and the second glass plate: and a printed circuit board having electronic components and guide pins having a flat frontal face bearing on the printed circuit board and secured on the printed circuit board by solder; wherein the printed circuit board is embedded between the first and second glass plates such that that guide pins are inserted into the passthroughs.

11. The composite window pane according to claim 10 , wherein the guide pins comprise a head facing towards the printed circuit board, on which the frontal face is located, and a shaft facing away from the printed circuit board, which is thinner than the head.

12. The composite window pane according to claim 11 , wherein a cross section of the head of the guide pin is larger than a cross section of the passthrough that accommodates the shaft of the guide pin.
