Abstract
Conductive adhesive bonds are used preferably where the contact bonds are subject to great temperature variations, for example, on a throttle valve controller. In order to increase the mechanical stabilization of the conductive adhesive bonds, the surface of the contacts are machined and provided with structures such as ribbing, prickles, etc. As a result of this structuring, the conductive adhesive interlocks mechanically at these points. This leads to a high contact reliability also at extreme temperature changes.
Claims10
A conductive adhesive bond on at least one mechanical contact, wherein the contact is structured on a surface thereof, and wherein the conductive adhesive interlocks mechanically at points of the structure.
A metal contact having protruding structures formed on a surface thereof for facilitating interlocking adhesion to a conductive adhesive, the conductive adhesive providing conductance between the metal contact and a conductor, wherein at least a portion of the protruding structures are embedded in the conductive adhesive.
A conductive bridge comprising:
- at least one metal contact extending from the conductive bridge for providing an electrical connection between the conductive bridge and a conductor, the metal contact having structures formed thereon,
- wherein at least a portion of structures formed on the metal contact are embedded in a conductive adhesive thereby providing adhesion areas for interlocking the metal contact within the conductive adhesive, and
- wherein the conductive adhesive facilitates electrical connection between the metal contact and the conductor.
