Nanosecond laser is used for precise dicing of GPP wafers.
Product advantages:
• High processing quality
The cutting line width is narrow (taking ultraviolet dicing as an example: including HAZ ≤ 30 ± 5 μm) , small edge collapse ≤ 10 μm
• High processing efficiency
UPH ≥ 15 (take 40mil, 5-inch GPP wafer as an example, including automatic loading and unloading)
• Good processing stability
Nanosecond laser has high power stability and good beam quality (M ² < 1.5)
