Scene defaults

Look up initial wafer, walking and environment values, their units and accepted ranges.

This reference applies to vFactory in Cloud 2.1.2.10 and Windows 2.1.2.3.

New scenes start with these wafer, walking and environment values. Open Fab settings to edit them.

Wafer and walking values

Wafer fields are under Floor and wafer. Walking fields are under Walk.

Field

Default; accepted range

Wafer diameter

300 mm; 25–450 mm

Wafer thickness

0.775 mm; 0.1–2 mm

Load-port wafer height

900 mm; 0–3000 mm

Eye height

1.6 m; 1–2.2 m

Body radius

300 mm; 150–600 mm

Walking speed

1.4 m/s; 0.2–5 m/s

Turn rate

90 °/s; 15–360 °/s

Environment values

Open Environment for the recorded scene environment values.

Field

Default; accepted range

Ambient temperature

21 °C; 15–30 °C

Relative humidity

45 %RH; 20–70 %RH

Airborne particle cleanliness (dust)

ISO 14644-1 class 5; classes 1–9, whole numbers

Downflow air velocity

0.4 m/s; 0–1 m/s

Room pressure differential

Coordinates and stored units

Stored lengths use millimetres and angles use degrees. The origin is the south-west floor corner: X points east, Y north and Z up from the floor.
