Model 9139B Probe Card Adapter Instructions Section 3: Installation
9139B-901-01 Rev. A / January 2019 3-11
Performance verification
A matrix test is run as part of system diagnostics and requires a blank (unpopulated) probe card. Run
a matrix test after the probe card adapter installation to check for leakage, open connections, or
shorted connections. Do not run a matrix test after installing each probe card.
During leakage tests, high voltages are present on the probe card adapter.
You must install a blank probe card in the probe card assembly to run diagnostics. A blank probe
card is supplied with the probe card adapter. You must keep this blank probe card.
The clean surface of the blank probe card provides a known, low-leakage test environment. The
unmodified Kelvin connections assure accurate continuity tests.
Handling and storage of the blank probe card is important (see Handling precautions (on page 1-4)).
For accurate leakage tests, follow these precautions:
•
Do not populate the blank probe card; it must remain unpopulated.
•
Store the blank probe card in a protective container in a clean, low-humidity environment.
•
When installing the blank probe card, handle it by the edges; do not touch the surface of the
probe card.
For more information about running system verification and diagnostics, refer to the diagnostics and
verification manual for your system.
Performance verification using system diagnostics
Using the blank probe card provided with the 9139B, run the matrix test from the system diagnostics
tool on your Keithley parametric test system to verify probe card adapter performance.
For more information about the system diagnostics and verification tool, refer to the Diagnostics and
Verification Manual for your system.
