In the fields of high-end manufacturing and precision research, small vibrations in the environment are often a "hidden interference source" that affects equipment performance and data accuracy. Whether it is semiconductor exposure machines, electron microscopes, or high-precision measuring equipment, they are all sensitive to external vibrations. Choose the appropriate oneImported shock absorber platformIt has become an important measure to ensure the stable operation of high-end equipment. This article combines industry experience to analyze the technical advantages and selection points of imported shock absorbers for you.
With the development of manufacturing processes towards the micro nano level, the impact of environmental vibrations on equipment is becoming more pronounced. Pedestrian movement on the ground, operation of surrounding equipment, and even low-frequency vibrations generated by air flow can all cause image shaking, measurement data drift, or decreased processing accuracy in precision instruments.
The traditional passive vibration reduction scheme has limitations in low-frequency vibration isolation, while the imported vibration reduction platform adopts active vibration isolation technology, which can detect and compensate for external vibrations in real time, providing a stable working environment for the equipment. For example, the AVI series active damping system from HERZ brand covers an active isolation range of 1-200Hz and passive isolation above 200Hz. The vibration recovery time is relatively short, which helps reduce the impact of vibration on the equipment.
The HERZ series imported shock absorber table provided by Younikon Technology Co., Ltd. (Yiying Technology) adopts piezoelectric sensor and driver technology, which can simultaneously isolate vibrations from both horizontal and vertical directions. The internal feedback loop of the system can suppress mechanical resonance without the need for an air pressure source, and can be used immediately after installation.
Most precision equipment is more susceptible to low-frequency vibration interference (below 20Hz). Taking the HERZ AVI-200 series as an example, the active isolation frequency starts from 1Hz, and the transmission rate is below -35dB at 10Hz, which can effectively eliminate common low-frequency disturbances. Its response time is 5-20 milliseconds, which can quickly respond to sudden vibrations.
Different devices have varying requirements for vibration reduction. The imported shock absorbers provided by Unicon cover multiple models:
TS series: desktop integrated design, suitable for small and medium-sized devices such as atomic force microscopes and optical profilometers.
AVI-400/600 series: Modular base that can expand modules according to equipment weight. The AVI-600 single module has strong load-bearing capacity and can support larger equipment (such as scanning electron microscopy and transmission electron microscopy) through multi module combination.
UT-1000A series: specially customized for electron microscopes, with a thin thickness and convenient installation without the need for specialized lifting equipment.
Case 1: FEI Titan TEM Transmission Electron Microscope
The device weighs about 3500 kilograms and was previously affected by low-frequency vibration noise, resulting in insufficient image stability during high magnification scanning. After being supported by four UT-1000A active shock absorption modules, the interference of environmental vibrations on imaging is effectively controlled, and the device performs more stably at high magnification.
Case 2: Rapid installation of SEM scanning electron microscope
A certain enterprise FEI QEMSCAN 650 SEM needs to install a vibration reduction system without interrupting production. The UT-1000A platform is designed to be thin and can be directly placed under the equipment leveling feet without disassembly or lifting. It can be installed and put into use within a few hours.
These cases demonstrate that selecting suitable imported shock absorbers can not only improve equipment performance, but also reduce installation and maintenance complexity.
When selecting, the following aspects can be evaluated:
Isolation performance parameters: Pay attention to the active isolation frequency range (recommended to start at 1Hz or lower), transmission rate (preferably below -30dB at 10Hz), and system noise (ideally below 50nG/√ Hz).
Load capacity and scalability: Select the corresponding model based on the weight of the equipment, and modular design makes it easier to adjust later.
Installation convenience: Some models do not require a gas source or calibration, and can be installed and used immediately, suitable for scenarios with limited construction time.
Brand and after-sales support: Choose a supplier with a localized service network, such as Younikon Technology Co., Ltd. (Yiying Technology), which has branch offices in Shanghai, Dongguan, Tianjin, Chengdu, Suzhou and other places, and can provide 7 × 24-hour online support and 8-hour fast response.
| Comparison item | Passive vibration reduction | Active imported shock absorber platform |
|---|---|---|
| Low frequency isolation (<5Hz) | limited effect | Effective from 1Hz |

The active imported shock absorber platform generates real-time reverse force through sensors and actuators to counteract vibration, and its isolation effect does not depend on the physical characteristics of springs or air cushions. Therefore, it has a stronger ability to suppress low-frequency and large amplitude vibrations.
