Vibration Isolation Case Studies

(end user Ruijin Hospital, Shanghai, China) Hitachi High-Tech HT7800 Transmission Electron Microscope (TEM) DVIA-ML1000 installation report — the active isolation platform meets the vibration specification on all axes (vertical, left-to-right, and front-to-back all PASS on both the floor and the DVIA-ML1000). Per-axis Autospectrum plots, the client tuning request form, and the installation photo are published.

J&L Tech (development lab, Ansan branch) residual stress measurement system DVIA-ULF1500 installation report. After installation, tuning and vibration measurement were performed with the equipment installed and Turned On. On the floor all three axes measured at the VC-C level, while on the DVIA-ULF1500 platform the vertical (Z) axis reached VC-G and the left-to-right (X) and front-to-back (Y) axes reached VC-E. Per-axis Autospectrum and VC Curves plus the installation photo are published.

Tier-1 electronics component manufacturer B1 1F Clean Room BGA PSP plating-thickness gauge DVIA-P2200 installation report — tuning and vibration measurement in the IDLE state; VC-B met on all axes for both floor and the DVIA-P2200 platform.

TF AMD Microelectronics (Penang, Malaysia) TESCAN AMBER X GMH FIB-SEM DVIA-ML1000 installation report — the active isolation platform meets the vibration specification on all axes (floor vertical fails while the DVIA-ML1000 platform passes); vertical/left-to-right/front-to-back autospectrum, VC curves, and transmissibility published.

Korea Institute of Science and Technology (KIST) L3 Building 1F Line JEOL JBX-A9 E-Beam Lithography DVIA-P4000 installation report — tuning and vibration measurement performed with the equipment Turned On, IDLE; all axes (vertical, left-to-right, front-to-back) PASS on both the floor and the DVIA-P4000 platform. The system was tuned for long-term operational stability due to an unstable site air supply.

DVIA-MO1000 installation report for the STM at Epin Instruments Technology Co., Ltd. In Shanghai, China, delivered through channel — isolator serial 241101R2, installed and written up on June 22, 2026 on the 2nd tuning trial. The report records no official vibration specification for the site, and the measurement summary reads the floor as VC-C vertical, VC-F left to right and VC-E front to back, with the platform reaching VC-F vertical and VC-G on both horizontal axes. All nine UI-program plots (Autospectrum, VC Curves and Transmissibility for each of the three axes) and the photograph of the STM standing on the platform are published.
