How Much Does Lam Research 716-058766-807 Cost in 2026?

Used units for the 716-058766-807 Edge Ring (301mm) trade between $1,200–$1,800 in 2026, while refurbished variants command $2,500–$3,000. These prices represent 40–60% savings versus new OEM pricing (typically $5,000–$6,500). Caveat: Parts with >500 process cycles in high-density plasma environments show >30% higher failure rates during leak testing. Always verify cycle history via the tool’s process log or the seller’s maintenance records. Refurbished units include ceramic resurfacing and vacuum seal replacement; confirm if plasma-facing surfaces retain original contour specifications.

716-058766-807 Specifications and Compatible Tools

This edge ring operates at 1.5–3.0 mTorr pressure, 13.56 MHz RF frequency, and 200–400°C process temperatures. Dimensions: 301mm OD × 15.2mm height, with a 0.002” radial tolerance. Compatible tools include Lam Research Plasmalab Series 700 (2012–2015), 800 (2014–2017), and 900 (2016–2018) etch platforms. Exclusion: Do not install on Plasmalab 820 systems using part number 716-058766-808—incorrect geometry causes plasma instability. Verify tool model and edge ring port alignment before purchase. Ceramic composite construction requires matching thermal expansion coefficients (CTE 5.2–5.5 ppm/°C) for long-term vacuum integrity.

What to Check Before Buying a Used 716-058766-807 in 2026

Surface cracks/microfractures: Use a 10X loupe and UV light; reject parts with cracks >0.1mm in plasma-facing zones.
Thickness measurement: Confirm minimum 2.8mm wall thickness via digital micrometer at three axial points; <2.5mm indicates excessive erosion.
Surface finish: Profile plasma-exposed surfaces with a 3D stylus profilometer; Ra >0.2µm roughness correlates with deposition defects.
Cycle count: Cross-reference with tool logs; parts exceeding 500 cycles in Cl2/O2 chemistries show 40% higher delamination risk.
Leak test: Perform helium mass spectrometry at 1×10⁻⁶ mbar·l/s; failures indicate sealant degradation. Avoid units >8 years old without full refurbishment.
