Then for:
•
Model 4200 — Connect the appropriate SMU from the Model 4200 directly into each triax connector.

Handling and cleaning
When inserting or removing a component from the test connector, use care not to touch the PC board or socket. This will help
avoid contamination from body oils or other foreign matter. The current leakage specifications depend upon a clean fixture. Con-
tamination could cause degraded performance, which might increase current leakages beyond specified limits.
Handling
Observe the following precautions when handling components:
•
Wear cotton gloves.
•
Avoid unnecessary touching of the test connector and PC board.
Cleaning
To clean the test fixture:
•
Swab the test connector and PC board area with methanol.
•
Quickly dry the test connector after cleaning by directing dry nitrogen gas over the PC board area.
•
After cleaning, allow the test fixture to dry in a 50˚C, low-humidity environment for one hour.
