Ultra-Violet (UV) Laser Ablation
What is UV laser ablation?
Ablation is defined as removal or erosion of something. Ultraviolet laser ablation is technology used to mimic the wearing a way of natural objects that are usually found in nature; like the erosion of rock or evaporation of snow.
The UV laser ablation process explodes material rather than melting it, which results in a sharper, cleaner edge and less thermal influence when laser cut. A-Laser operates on a wide range of materials with our UV laser ablation systems, from polyimides to precious metals to thermal substrates. Additionally, these materials are seen with adhesive combos that are clad or bonded. Our UV ablation specialists have built a vast library of tools to accommodate these various material combinations, their thicknesses, and cut requests of our customers.
By utilizing UV laser ablation, we can achieve incredibly intricate and complex patterns without charring the material and maintaining tolerances of +/- 12 microns or .0005″.
Ultraviolet (UV) Laser ablation will produce finely cut and detailed features in precision parts manufacturing for industries ranging from medical to engineering. This application is typically used on non-metal parts but can also be used on ultra-thin metal as well.
What sets A-Laser apart from the competition is offering cutting services with UV lasers that run at over 7 watts of power. Our lasers have:
- 20 micron beam
- Pulse repetition rates up to 250 kHz
- 355 nanometer wavelength
- Pulse length <100 nanoseconds
- Contact free laser ablation ensures material integrity
Kapton (Polyimide) and PEEK (polyetheretherketone)
Two materials our laser cutting service sees often are Kapton and PEEK. Both cut very nicely on the UV laser cutting systems and both are used for highly technical applications in a wide variety of industries. For our purposes, we know that both Kapton and PEEK laser cut with very little carbon residue, hold tolerances very well, and laser cut with very clean edges. We are curious if anyone out there wants to debate the features and benefits of thermoset vs thermoplastic films such as Kapton and PEEK. Our laser cutting service works with a wide range of engineers, so it would be very interesting to hear input from the various industries.
