Abstract:
A universal socketless integrated circuit (IC) electrical test fixture is provided. The test fixture is made up of a probing platform to accept and heatsink an IC. The IC has electrical contacts formed on a bottom surface in an array of m rows, where each row includes n, or less contacts. A probe arm includes p probe pins, where p is greater than, or equal to n. A clamping mechanism mechanically interfaces the probe arm probe pins to a row of IC contacts under test. An electrical measurement device has a first interface connected to the p probe pins of the probe arm to measure electrical characteristics associated with the IC contacts under test. The probe arm, clamping mechanism, and probe platform work in cooperation to electrically interface any row of the IC contacts with the electrical measurement device.
