Only probe tips with a shaft diameter of 18 to 22 mils can be used with the E probe tip holder mechanism. However, most probe tips have a shank diameter of 20 mils. S series probe tip holders are available in four different pre-bent shapes. Shape 1 - Straight. Straight probe tip holders are suitable for many general probing applications, especially when using one of Signatone's pivoting head micropositioners.
Straight holders can also be bent by the user to satisfy a particular applications.
The brass material can be bent one time without breaking. Shape 2 - Bent for use when probing wafers as well as packaged parts. For use with the Leica Microzoom or Mitutoyo Finescope as well as any of the lower powered microscopes. This shape is normally not needed if the micropositioner is equipped with a pivoting head assembly. Shape 3 - Bent for use when probing simultaneously with a probe card and micropositioners.
