Bimos ESD chairs are static-dissipative work chairs for Electrostatic Protected Areas — electronics assembly, semiconductor, PCB and inspection work. Every contact surface forms a continuous path to ground so charge drains away instead of building on the operator and discharging into a device. Phil Industries supplies the premium Bimos ESD range in Singapore.
How an ESD chair works
| Component | Requirement | Why it matters |
|---|---|---|
| Seat & backrest shell | Static-dissipative material | Stops charge generating as the operator moves |
| Castors / glides | Conductive | Completes the path from seat to floor |
| Gas lift & frame | Conductive | Links upper surfaces to the base |
| ESD floor / mat | Grounded | The chair can only discharge to a grounded floor |
Specify correctly
- Compliance — look for ANSI/ESD STM12.1 (chair resistance testing) within an S20.20 programme.
- The whole path matters — an ESD chair on a non-grounded floor is not an ESD control.
- Model lines — ESD Neon, ESD Nexxit, ESD Unitec, ESD Basic, ESD Labsit.
- Seat material — PU / integral foam wipes clean and resists wear better than fabric.
Where they’re used
- Semiconductor fabs and PCB assembly lines
- Electronics inspection, rework and test benches
- ESD-protected areas (EPAs) under an S20.20 programme
- Cleanrooms handling electronics — see Cleanroom Chairs
Frequently asked questions
What makes a chair ESD-safe?
The seat shell, castors, gas lift and frame are all static-dissipative or conductive, forming a continuous path to earth. Charge drains to the grounded floor instead of accumulating on the user.
Do I need an ESD floor as well?
Yes — an ESD chair discharges through the floor. Without a grounded ESD floor or mat, the path is incomplete and the chair cannot do its job.
What standard applies?
ANSI/ESD STM12.1 covers chair resistance testing; chairs are typically specified as part of an ANSI/ESD S20.20 ESD control programme.
Is there a lower-cost option?
Yes — compare these premium Bimos ESD chairs with our value ESD Safe Chairs range; both are static-dissipative.
