Ultrafast Laser Physics and Material InteractionsIndium Laser Cleaning Settings
When laser cleaning Indium, you must start with a cautious low-power setup to avoid melting its soft surface, unlike tougher metals that handle more heat. Begin by pulsing gently to penetrate its high reflectivity, which reflects energy better than copper does. Slowly increase scan speed across the area, ensuring even passes that restore its conductive finish without warping. This approach clears contaminants while preserving Indium's malleability for electronics use.

Parameter Relationships
Shows how changing one parameter physically affects others. Click any node to see its downstream impacts and role.
Power Range
Amplifies damage risk in Pulse Width. Keep low to maintain safety margins.
Spot Size
Same power in a smaller spot creates much higher energy density.
Pulse Width
More power means higher peak intensity. Too much can damage the material.
Pass Count
Using more passes means you can use lower power and still get the job done.
