General Cleaning
The importance of cleanliness cannot be overemphasized. Dirt in the
testhead will cause contact problems and overheating.
• MINT pins (fixture interface pins) — Dirt will cause high- impedance
contacts and pin sticking.
• Pin cards, mother cards and vents — Air flow through the system
causes a buildup of dirt on pin cards and Mother Cards and clogs air
vents in the testhead, contributing to system overheating. Check and
clean these areas as necessary.
• Test fixtures — When not used, test fixtures should be stored in a clean
environment such as a closed cabinet or carousel. Check and clean as
necessary.
• Keep a Pin Verification Fixture or dust cover(s) on the testhead
whenever a fixture is not in place.
• System covers — Clean with a water moistened cloth when necessary.
Do not use cleaning solutions.
