• Can be used with Agilent 4156, 4140B, Keithley 4200, 6517A SMUís for Leakage Measurements, and Agilent 4284/4285 LCR For Capacitance Measurements

System as shown at Semicon West 2003 

• Install known-good probe cards in your production floor equipment.
• Debug and analyze probe card problems independent of your production floor.
• Return out of spec cards to your probe card vendor without the cards ever reaching and disrupting your production floor.

Our Probe Card Characterization System makes all this possible.

The Probe Card Characterization System (PCCS) is a complete automated test system designed to efficiently and exhaustively characterize probe cards. Requiring only the operator to insert the probe card and start the test, the system will run through a test sequence you define, automatically recording, compiling, and storing the data youíve requested. Your test sequence can be as simple or as complicated as the situation warrants; the PCCS can test for guarded signal (normal), guard-to-signal, and guard-to-guard trace current leakage and trace capacitance. The PCCS can test the whole probe card, spot-test specific traces, or test any other combination of traces. All of this is set up in your configuration fileóyour engineer sets up the test in advance, your operator loads the card and presses go. No additional intervention is needed until the results are complete, and the next card can be loaded into the system. The PCCS gets you comprehensive results fastóall without tying up your production floor.

Use your production floor as it was intendedófor production.

 Contact-Block Hardware Component

ÿ       Integrated  (Trace-Probe-Head) Contact-Block Switch Matrix for reduced settle time during measurements
ÿ        Switch matrix provides computer controlled selection between I-V (SMU) and C (LCR) measurement modes and the test configuration of any probe card trace
ÿ       Available in one, two, and four quadrant configurations*
(Quadrant is defined as one Measurement channel with associated (adjacent) trace contact blocks; enabling cross-trace leakage/capacitance measurements)
ÿ       Embedded process controller for computer controlled access to switch matrix resources
ÿ       Incorporates a shield barrier for optimal measurement quality guarded signal (normal) mode.
ÿ       Contact-Block assembly allows electrical configuration for the following trace tests:

• 
  v      Guarded Signal
  v      Signal to Guard
  v      Guard to Guard
   

• All connections are shielded and guarded to provide a repeatable, consistent, and optimal settle time test solution.

• All measurement channels are tested to confirm base line leakage of less than 5fA @ 100 VDC
