What to Check Before Buying a Used Varian 10716821 I/O PCB Card Rev. B

Visual inspection: Reject boards with cracked capacitors (>5µF electrolytic) or discolored VRM modules (look for brownish tinge near CPU heatsink).
Continuity test: Use a multimeter to verify <0.1Ω resistance across all I/O header pins; >10Ω indicates fractured traces.
Connector wear: Inspect LVDS mating edges with a digital microscope—reject if contact wear exceeds 5% of blade width.
Firmware version: Boot the board in a test rig to confirm Rev B firmware (Rev A units lack thermal shutdown for overvoltage).
Age check: Units manufactured pre-2010 may have failed tantalum capacitors (check date codes on AVX part numbers).
