several points (Make sure the copper foils are pressed between the cement floor and
semi-conductive floor and is connected with the grounding cable).
l
EMI Protection Requirements
Electric field strength is 300mV/m and magnetic field strength must not exceed 11GS.
l Dust-Proof Requirements
The density of dust particle whose diameter is larger than 5μm must be less than
à
30000/m
Dust particles must be non-conductive,
à
non-corrosive.
The following measures are recommended for dust-proof in the lab:
Doors and windows must be sealed. The external windows must be sealed with
à
double-layer glass and the doors must be sealed with dust-proof sealing strips.
The ideal condition is to seal the lab with a shutter equipped with a dust filter
device.
Work clothes and slippers must be kept clean and changed regularly.
à
It is recommended to place operation equipment in outer room, thus avoiding
à
frequent access and opening/closing of lab door.
Keep a higher relative humidity within the permissible range in the lab to reduce
à
static electricity adsorption of dust.
Walls and ceiling of the lab must be painted or pasted with wall paper. It is better
à
to use lusterless paint.
