UV laser application trends
Laser beams typically provide a low-pressure alternative to mechanical printed circuit board processing, such as milling or automatic board cutting. But ultraviolet lasers have the benefit of other lasers that limit thermal stress. This is because most UV laser systems operate at low power. What is the application trend of UV lasers?
Small heat affected zone
By using a process sometimes referred to as “cold ablation”. The UV laser beam produces a reduced heat affected zone that minimizes the effects of edge processing. Carbonization, and other thermal stresses, while using higher power lasers. These negative effects usually exist.
Excellent positioning accuracy
Ultraviolet lasers have a shorter wavelength than visible light and are therefore invisible to the naked eye. Although you can’t see these laser beams, these shortwaves allow the UV laser to focus more precisely, resulting in extremely fine circuit characteristics while maintaining excellent positioning accuracy.
In addition to short wavelengths and low workpiece temperatures. High-energy photons in ultraviolet light allow UV lasers to use in large PCB circuit board combinations. From standard materials such as FR4 to high-frequency ceramic composites and flexible PCBs including polyimide. Various materials such as materials are suitable.
High absorption rate
Ultraviolet lasers exhibit extremely high absorptivity when applied to resins and copper, and have an appropriate absorption rate when processing glass. Only expensive excimer lasers (wavelength 248 nm) will achieve better overall absorption rates when processing these primary materials.
The variability of this material makes UV lasers the best choice for a variety of PCB materials in many industrial applications, from the most basic circuit boards, circuit wiring, to advanced processes such as pocket-sized embedded chips.
Precision focusing ability
Ultraviolet laser systems directly from computer-aided design data to processing boards mean that no intermediaries are need during board production. Coupled with the precise focusing of UV light, the UV laser system can implement highly versatile solutions and repeat positioning.
Yinggu·picosecond UV laser
The picosecond UV laser produced by Yinggu Laser has a series of advantages such as narrow pulse width, short wavelength, high photon energy and small focusing spot, which makes the processing size smaller and the processing precision can be further improved.
This picosecond UV laser can be said to have unique advantages in the field of precision laser processing. Compared with similar products, it is more prominent in terms of function and cost performance, and it is a good choice.
