Vibration Isolation Case Studies

DVIA-MB1000 serial 160706R1 installation report for a ZEISS FE-SEM Sigma 300VP — tuning 2025-12-24, report written 2026-01-07 by Chaewon Lee (DAEIL SYSTEMS). Published plots follow DOCX §2a mapping: vibration specification capture under **Vibration Specification**, vertical / left-to-right / front-to-back transmissibility under **Data and Image**, then equipment photograph. Decorative letterhead raster after the website line (image1) is omitted; Reference uses the standard VC markdown table only (no Generic Vibration Criteria bitmap — image7.emf).

DVIA-MB1000 (serial 161213R2) tuning and vibration measurements for a TESCAN CLARA FE-SEM relocated to the Tier-1 Electronics Component Manufacturer Busan site A6 building 3F incoming inspection room. Tuning on 2026-01-06; report written 2026-01-07. The public page publishes nine measurement plots (VC curves, autospectra, transmissibility for vertical, left-to-right, and front-to-back). The decorative banner image above the title block and the Generic Vibration Criteria bitmap under 참고자료 are omitted in favor of the standard VC reference markdown table.

DVIA-U1000 re-tuning worksheet (serial 220919R6-1) for Goertek Inc. with ZEISS FE-SEM Sigma 300; tuning December 19, 2025, report written January 7, 2026 (Chaewon Lee). Overview cites Z-axis oscillation and gain reduction; location line "-" (N/A). Publishes Vertical, Left to Right, and Front to Back transmissibility UI plots only; equipment picture line Photo Not Allowed; decorative header bitmap and Reference EMF omitted — Reference uses the standard VC markdown table.

DVIA-UB700 (S/N 221024R5) inspection report for ZEISS FE-SEM Sigma 300 at Hanyang University, Natural Sciences Building, Room 112. Turned on/IDLE measurements: vertical, left-to-right, and front-to-back VC curves, autospectra, and transmissibility. LPF tuning on left-to-right and front-to-back removed initial active-mode oscillation; all directions meet vibration specification at pass levels shown in the measurement summary.
