Abstract
A probe polish burnishing assembly has a stem having a substantially spherical surface. This spherical surface makes intimate contact with the concave surfaces commonly present at the tips of set screws used to align the assembly, decreasing the likelihood of slippage and chipping of the stem. Alignment of the assembly is thus made more precise, and the useful life of the assembly is improved. Furthermore, the likelihood of damage to the probe during burnishing is lessened.

A method for burnishing a probe device having a plurality of probes, the method comprising:
- providing a burnishing pad supported by a support member having a surface at least partially defined by a truncated sphere;
- providing a plurality of set screws, each set screw having a concave surface located at a distal end, the concave surfaces making intimate contact with the surface of the support member;
- selectively tightening the set screws to render a plane defined by the burnishing pad parallel to a plane defined by distal ends of the probes;
- and
- rotating the burnishing pad.
A burnishing assembly, comprising:
- a burnishing pad;
- and
- a support member arranged to support the burnishing pad and having a surface substantially defined at least in part by a truncated sphere;
- a plurality of set screws configured to alter the orientation of the burnishing pad, each set screw having a concave surface located at a distal end, the concave surfaces making intimate contact with the surface of the support member.
A burnishing assembly, comprising:
- a burnishing pad;
- a support member arranged to support the burnishing pad and having a surface at least partially defined by a truncated sphere;
- a plurality of set screws configured to alter the orientation of the burnishing pad, each set screw having a concave surface located at a distal end, the concave surfaces making intimate contact with the surface of the support member;
- and
- a housing configured to retain the set screws and having a seating configured to accept the support member, the seating having a surface defined by a portion of a sphere concentric with the truncated sphere defining the surface of the support member.
