  • Method for reducing integral stress of a vertical probe with specific structure
    Publication number: 20070007974
    Abstract: A method for reducing integral stress of a vertical probe with specific structure is disclosed. The vertical probe includes a probe tip, an insert part and a bent part. The bent part has a first circular arc and a second circular arc and the second circular arc is provided with a radius much greater than that of the first circular arc and the second circular arc is farther away from the probe tip and smoothly extends from the first circular arc. The integral stress of the probe during probing is effectively reduced to avoid overstress.
