Probe Head Including a Guide Plate with Angled Holes to Determine Probe Flexure Direction
Last updated:
Abstract:
Vertical probe arrays having angled guide plates are provided. With this configuration, the probes can be straight conductors (when mechanically undeformed) and the mechanical bias provided by the angled guide plates can ensure the probes have a well-defined deformation when the probe array make contact to the device under test. This allows the use of straight conductors as probes without suffering from probe shorting and mechanical interference caused by straight probes buckling in unpredictable directions when vertically compressed.
