Abstract

A configuration and also a method for the configuration in which, the configuration has at least one electronic device with associated contact connections and at least one printed circuit board with external contacts. The printed circuit board is electrically coupled to the electronic device. At least the metallic surfaces of the configuration are covered by a plasma-polymerized polymer layer.

Claims (44)

1. A method for producing a configuration having at least one electronic device that is electrically coupled to at least one printed circuit board, the method which comprises:

providing a configuration having at least one electronic device with associated contact connections and at least one printed circuit board with external contacts;

using a soldering paste to mask the external contacts;

introducing the configuration into a plasma chamber;

applying a polymer layer, at least to metallic surfaces of the configuration, using plasma polymerization;

removing the configuration from the plasma chamber;

if necessary, removing the polymer layer from the contacts of the printed circuit board and from the contact connections of the electronic device; and

soldering the contacts of the printed circuit board and the contact connections of the electronic device together such that, in the configuration, the printed circuit board and the electronic device are electrically coupled together.

2. The method according to claim 1 , which comprises:

performing the step of applying the polymer layer by covering all surfaces of the at least one electronic device and all surfaces of the at least one printed circuit board with the polymer layer.

3. The method according to claim 1 , which comprises:

performing the step of applying the polymer layer such that during the plasma polymerization, monomers are polymerized in the plasma chamber to form longer-chain hydrocarbons.

4. The method according to claim 3 , which comprises:

performing the step of applying the polymer layer such that during the plasma polymerization, short-chain prepolymers are polymerized in the plasma chamber to form longer-chain hydrocarbons.

5. The method according to claim 1 , which comprises:

performing the step of applying the polymer layer such that during the plasma polymerization, short-chain prepolymers are polymerized in the plasma chamber to form longer-chain hydrocarbons.

6. The method according to claim 1 , which comprises:

screen printing the soldering paste to mask the connection contacts that will be soldered.

7. The method according to claim 1 , which comprises:

stencil printing the soldering paste to mask the connection contacts that will be soldered.

8. The method according to claim 1 , which comprises:

apportioning the soldering paste to mask the connection contacts that will be soldered.

9. A method for producing a configuration having at least one electronic device that is electrically coupled to at least one printed circuit board, the method which comprises:

providing a configuration having at least one electronic device with associated contact connections and at least one printed circuit board with external contacts;

using a soldering paste to mask the external contacts of the printed circuit board;

contact-connecting the contact connections of the electronic device to the external contacts of the printed circuit board;

introducing the configuration into a plasma chamber;

applying a polymer layer, at least to metallic surfaces of the configuration, using plasma polymerization;

removing the configuration from the plasma chamber; and

soldering the contacts of the printed circuit board and the contact connections of the electronic device together such that, in the configuration, the printed circuit board and the electronic device are electrically coupled together.

10. The method according to claim 9 , which comprises:

performing the step of applying the polymer layer by covering all surfaces of the at least one electronic device and all surfaces of the at least one printed circuit board with the polymer layer.

11. The method according to claim 9 , which comprises:

performing the step of applying the polymer layer such that during the plasma polymerization, monomers are polymerized in the plasma chamber to form longer-chain hydrocarbons.

12. The method according to claim 11 , which comprises:

performing the step of applying the polymer layer such that during the plasma polymerization, short-chain prepolymers are polymerized in the plasma chamber to form longer-chain hydrocarbons.

13. The method according to claim 9 , which comprises:

performing the step of applying the polymer layer such that during the plasma polymerization, short-chain prepolymers are polymerized in the plasma chamber to form longer-chain hydrocarbons.

14. The method according to claim 9 , which comprises:

screen printing the soldering paste to mask the connection contacts that will be soldered.

15. The method according to claim 9 , which comprises:

stencil printing the soldering paste to mask the connection contacts that will be soldered.

16. The method according to claim 9 , which comprises:

apportioning the soldering paste to mask the connection contacts that will be soldered.
