l 75 µm ≤ precipitable dust diameter ≤ 150 µm
Take the following measures to meet the requirements:
l Use dustproof materials for ground, wall, and ceiling construction.
l Use screens on the door and windows facing outside. The outer windows should be dust-
proof.
l Clean the equipment room regularly and clean the air filter monthly.
l Wear shoe covers and ESD clothing before entering the equipment room.
