Lam 716-022493-343 Specifications and Compatible Tools

This 300mm bottom uniformity ring operates at 13.56MHz RF, 2.5–5mTorr pressure, and 300–400°C chamber temps. Dimensions: 305mm OD × 75mm ID × 20mm H. Compatible with Lam 2300 Exe (2003–2008), 2300 Versa (2005–2010), and 2300 Centura (2001–2006). Exclusion: Do not install in 2300 Centura models using part 716-022493-345—incorrect geometry causes plasma instability. Cross-check chamber serial numbers against Lam’s 2300-series compatibility matrix.

What to Check Before Buying a Used Lam 716-022493-343 in 2026

Surface integrity: Use a borescope to inspect for microcracks; reject parts with >3 cracks >2mm in high-heat zones.
Flatness: Measure with a 0.001” resolution dial gauge; deviation >0.05mm at the center bore invalidates uniformity.
Gas flow calibration: Test with a 5sccm–50sccm mass flow controller; ±5% deviation from OEM specs requires recertification.
Thermal history: Reject components with >500 documented thermal cycles (check Lam’s PM logs).
Coating wear: UV-Vis spectroscopy to confirm <10% loss of anti-reflective coating in critical areas.
