Abstract
A floating or compliant plate test socket device and method is disclosed. Three primary components, a fixed frame () receives a floating or compliant plate (), sit together atop a housing () which contains contact pins used for the electrical test of the DUT (device under test). In fixed plate () are bearings for reducing friction when the floating plate is driven downward by the DUT inserter. Embedded in sidewalls () are a plurality of vertical raceways () which receive bearings (). The raceways are borings, which have gap in the boring, in the fixed plate sidewalls () with the boring center spaced from the sidewall sufficiently that part of the bore removes part of the sidewall but allows the ball bearings to partially protrude from the gap formed in the incomplete semicircular boarding without the bearings being able to freely escape.
