Abstract

A plug contact is provided for the provision of a press contact with a mating contact. The plug contact is composed of an electrically conductive material. The plug contact has a first contact section for the provision of the press contact. The first contact section has, at least in places, an electrically conductive organic coating, and the organic coating contains a metal, an alloy, and/or an electrically conductive polymer. A printed circuit board arrangement is also provided.

First claim

The invention claimed is:

1. A plug contact for a press contact having a mating contact, the plug contact comprising:
a plug contact body composed of an electrically conductive material, said plug contact body having a first contact section for provision of the press contact, said first contact section having, at least in places, an electrically conductive organic coating, said electrically conductive organic coating including at least one of a metal, an alloy, or an electrically conductive polymer;
said plug contact body having a second contact section configured for connection with a second mating contact, said second contact section having, at least in places, an electrochemically deposited coating, and said second contact section spaced away from said electrically conductive organic coating.

2. The plug contact according to claim 1 , wherein said electrically conductive organic coating including at least one of the metal or the alloy, said metal and, respectively, said alloy is present in a form of particles in said electrically conductive organic coating, and said particles are in colloidal dispersion in an organic dispersion medium.

3. The plug contact according to claim 2 , wherein said metal is tin.

4. The plug contact according to claim 1 , wherein said electrically conductive organic coating includes at least one of a triazole, imidazole, benzimidazole, or a derivative of at least one of these substances.

5. The plug contact according to claim 1 , wherein said electrically conductive organic coating includes said electrically conductive polymer and said electrically conductive polymer contains at least one of polyaniline (PAni), polythiophene (PTh), polypyrrole (PPy), poly(3,4-ethylenedioxythiophene) (PEDT), Polythienothiophene (PTT), or a derivative of at least one of these materials.

6. A printed circuit board configuration, comprising:
a printed circuit board having a contact hole formed therein and an electrically conductive contact layer disposed around said contact hole; and
a plug contact composed of an electrically conductive material and having a first contact section disposed in said contact hole, said plug contact having a press-fitting electrical and mechanical connection to said electrically conductive contact layer, said first contact section having, at least in places, an electrically conductive organic coating, and said electrically conductive organic coating including at least one of a metal, an alloy, or an electrically conductive polymer;
said plug contact having a second contact section configured for connection with a second mating contact, said second contact section having, at least in places, an electrochemically deposited coating, and said second contact section spaced away from said electrically conductive organic coating.
