Abstract

An alternative method to epoxy ring construc- tion is described. Fixtures manufactured using con- ventional machine shop equipment, replace the prev- alent technique of molding epoxy around probe needles to hold them in place. These fixtures are fabricated from Delrin or ceramic materials and TOP machined in two pieces, a top and bottom as illus- trated in Figure 1. An elastomer covers the inside of the top fixture and controls needle contact force in the Z-axis. The bottom tixture uses grooves that serve as precision guides to control needle movement in X and Y axis.
