Abstract:
An elongated microelectronic spring contact element, comprising:a base end portion connected to an electronic component; an elongated beam portion integrally formed with the base end portion and arranged above a surface of the electronic component; a contact portion integrally formed with the elongated beam portion and arranged above the surface of the electronic component, wherein the microelectronic spring contact element is moveable in response to a force applied to the contact portion in the direction of the electronic component, the elongated microelectronic spring contact element providing an opposing force tending to move the contact portion away from the electronic component; an insulating coating entirely enveloping the base end portion and a majority of the elongated beam portion of the elongated microelectronic spring contact element, the contact region being substantially free of the insulating coating; a conductive coating, the conductive coating entirely enveloping substantially all of the insulating coating and being electrically isolated from the elongated microelectronic spring contact element; and an electrical contact disposed on the electronic component, the electrical contact providing a predetermined voltage level and being electrically connected to the conductive coating; wherein said predetermined voltage level controls an impedance of said microspring contact element.
