What to Check Before Buying a Used AMAT 0021-40940 in 2026

Ceramic coating thickness: Use a micrometer; <0.15mm Al₂O₃ layer requires recoating.
Radial wear: Measure OD with a digital caliper; >1.2mm erosion reduces plasma containment.
Crack inspection: Use a 10X borescope for microfractures in ceramic; reject any >0.05mm gaps.
Chamber cycle count: Units >30k cycles show accelerated erosion; verify via OEM logbook or PLC data.
Plasma uniformity test: Run a dummy wafer etch; >15% edge uniformity deviation indicates misalignment.
