High frequency vertical spring probe

摘要

A high frequency vertical spring probe is provided in the present invention. The probe includes an unclosed ring structure having a gap disposed therein to provide an elastic property for vertical deformation. At least a first contacting component and a second contacting component are disposed on the ring structure of the probe to provide electrical connection of an external component when the probe is compressed. The first contacting component is located near two terminals of the ring structure adjacent to the gap and the second contacting component is disposed vertically corresponding to the first contacting component. The probe can serve as the electrical connection between two components or can be installed in the probe card to provide chip testing with high-frequency, high-speed and good-contacting environment.
