Forensic Intelligence Report: Chamber Infrastructure
01
Thin-Film Deposition Control Hub
A precision Quartz Crystal Microbalance (QCM) feedthrough assembly engineered for thin-film deposition rate and thickness monitoring. This unit provides the critical electrical and thermal interface between the vacuum chamber and INFICON EasyRate, Sputtering, and CrystalSix sensor heads.
02
High-Fidelity Signal & Thermal Architecture
The unit integrates dual stainless steel cooling lines (≈ 8" length, ≈ 1/4" OD) designed to enable stable crystal temperatures even under high-energy sputtering conditions up to 450°C. Signal fidelity is secured via true coaxial transmission (BNC on atmosphere, Microdot on vacuum side), which minimizes noise and prevents electromagnetic interference (EMI) during sensitive deposition phase monitoring.
03
Forensic Audit: New Open Box (NOS)
Condition Note: Verified Tier 1 NOS status. The assembly is completely unissued and uninstalled. The CF 2.75" (CF40) flange displays pristine, factory-sharp, and unswaged knife-edges. It bears the clear factory engraving: "INFICON MADE IN USA 316 SS". Coaxial connectors are pristine. The ≈ 8" cooling tubes are clear with zero fluid history.
III. Operational Directives & Integration Protocol
Signal Routing: Route the coaxial BNC-to-Microdot cable internally to strictly avoid EMI coupling with surrounding chamber electronics. Standard INFICON in-vacuum cables are typically optimized at 30" (76 cm) lengths.
Coolant Management: Active thermal management is mandatory for high-temperature runs. Maintain coolant flow at ≥ 150–200 cc/min. Utilize strictly chloride-free cooling water to prevent stress corrosion cracking within the 316 stainless steel tubing.

BLUE DIAMOND PROTECTION PROTOCOL: ACTIVE
TOP RATED PROTECTION: This listing qualifies for Free 30-Day Domestic Returns. Per eBay Seller Protection policy for Top Rated Plus members, any item returned in a condition different from the original shipment (including but not limited to: installation witness marks on the CF flange, contamination/fluid history within the water cooling tubes, bent or damaged coaxial connector pins, or chemical etching) will result in an immediate 50% deduction from the refund to account for the catastrophic loss in unissued technical utility. Forensic Evidence: All returns must be photographed immediately upon arrival.
