Generic Vibration Criteria

Vibration Level Classification Description Vibration Allowance Criteria
Amplitude1)
µm/s (µin/s)
Precision2)
µm
Workshop (ISO) Level where people can clearly feel vibrations, suitable for workshops and other non-sensitive areas. 800 (32,000) N/A
Office (ISO) Level where people can feel vibrations, suitable for general office environments and places where vibrations are not a major concern. 400 (16,000) N/A
Residential Area (ISO) Level difficult for people to perceive, suitable for sleeping areas. Also suitable for computers, hospital recovery rooms, semiconductor probe test equipment, and microscopes with magnification below 40X. 200 (8,000) 75
Operating Theatre (ISO) Level where people cannot perceive vibrations, suitable for surgical equipment and microscopes with magnification below 100X. 100 (4,000) 25
VC-A Level suitable for optical microscopes with magnification below 400X, precision scales, and projection aligners. 50 (2,000) 8
VC-B Level suitable for inspection equipment such as lithography with a linewidth below 3 μm and steppers. 25 (1,000) 3
VC-C Level suitable for optical microscopes with magnification below 1000X, lithography and inspection equipment with precision below 1 μm (less sensitive electron microscopes), and TFT-LCD steppers/scanners. 12.5 (500) 1 - 3
VC-D Level suitable for high-spec electron microscopes (SEMs, TEMs), E-Beam systems, etc. 6.25 (250) 0.1 - 0.3
VC-E Level suitable for laser systems with long beam paths or extremely sensitive equipment such as nanometer-scale E-Beam lithography. 3.12 (125) < 0.1
VC-F Level suitable for ultra-precision research facilities. Achieving this vibration level is difficult in most places (especially cleanrooms). This is a standard for evaluating vibration levels rather than a design standard. 1.56 (62.5) N/A
VC-G Level suitable for ultra-precision research facilities. Achieving this vibration level is difficult in most places (especially cleanrooms). This is a standard for evaluating vibration levels rather than a design standard. 0.78 (62.5) N/A
  • 1) VC-A through VC-B represent amplitude values measured in octave bands from 8-80Hz, while VC-C through VC-G represent amplitude values measured in octave bands from 1-80Hz.
  • 2) In the field of microelectronics, precision refers to the linewidth, and in the medical field, it refers to particle size.
