(7) There should be no strong electromagnetic interference signal near the installation place of the equipment, and a radio transmitting station or a relay station is avoided around the equipment.
(8) The equipment is prevented from being placed in environments with serious dust such as metal polishing and grinding and the like, and is prevented from being operated in low-light environments.
The washer, workplace must remain bright.
(9) Some environments must be provided with electrostatic shielding measures such as installation of antistatic floors, grounding of equipment housings, and the like.
The plasma is only generated if the energy density is above a threshold value, which depends on the contamination layer or oxide layer being removed. This threshold effect is important for effective cleaning while ensuring the safety of the substrate material. There is also a second threshold for the occurrence of plasma. If the energy density exceeds this threshold, the substrate material will be destroyed.
In order to perform effective cleaning on the premise of ensuring the safety of the substrate material, the laser parameters must be adjusted according to the situation so that the energy density of the light pulse is strictly between two thresholds.
Each laser pulse removes a thickness of the contamination layer. If the contamination layer is relatively thick, multiple pulses are required for cleaning. The number of pulses required to clean a surface depends on the degree of surface contamination. An important result resulting from the two thresholds is the self-control of the cleaning. Light pulses with energy densities above the first threshold will reject contaminants until the substrate material is reached. However, the substrate is not damaged because its energy density is below the damage threshold of the substrate material.
