Abstract

A process for producing a contact-making device is provided for making electrical contact between components, which includes the step of producing an electrical zero-insertion-force connector which further includes the step of forming an elastic dielectric with at least two elastic dielectric layers and at least one structured metal layer disposed between the two elastic dielectric layers. The elastic dielectric has an upper side and an underside being the upper side and the underside, respectively, of the zero-insertion-force connector. The process also includes the step of structuring the elastic dielectric, forming a number of contact points on the upper side and the underside of the zero-insertion-force connector; and forming a number of electrically conducting connections in and through the elastic dielectric such that the electrically conducting connections connect a number of the contact points to one another.

Claims

1. A process for producing a contact-making device for making electrical contact between components, which comprises the steps of:

providing a basic metal layer, the basic metal layer being a metal foil;

alternatingly applying at least one dielectric layer of elastic dielectric material and at least one further metal layer of metal foil on the basic metal layers;

structuring the layers with holes to form vertical vias or through contacts;

structuring the basic metal layer and the uppermost metal layer to form exterior contacts; and

the elastic dielectric material forming a main body of the contact-making device.

2. The process according to claim 1, which comprises producing a multilayer interposer including at least two elastic dielectric layers between metal foils.

3. The process according to claim 1, which comprises applying the dielectric layer as a coating of liquid silicone rubber or polyurethane.
