Apparatuses for inspecting pogo pins of an electrical die sorting system and a method for performing the same

Abstract

Apparatuses for inspecting pogo pins of an electrical die sorting (EDS) system are provided and a method for performing the same are provided. Apparatuses for inspecting pogo pins that delivers electrical signals between a tester and a probe when dies on a substrate are electrically tested are also provided. The apparatuses may include a lower plate, an upper plate and/or a sensing unit. The lower plate may be positioned under a pogo block including the pogo pins. The lower plate may include a conductive layer electrically connected to lower end portions of the pogo pins. The upper plate may be positioned over the pogo block. The upper plate may include conductive plugs corresponding to upper portions of the pogo pins. The sensing unit, for generating signals, may be coupled to an electrical contact between the conductive plugs and the pogo pins.

Dependencies are inferred from the claim text.
