Abstract
A composite spring contact structure includes a structural component and a conduction component distinct from each other and having differing mechanical and electrical characteristics. The structural component can include a group of carbon nanotubes. A mechanical characteristic of the composite spring contact structure can be dominated by a mechanical characteristic of the structural component, and an electrical characteristic of the composite spring contact structure can be dominated by an electrical characteristic of the conduction component. Composite spring contact structures can be used in probe cards and other electronic devices. Various ways of making contact structures are also disclosed.
