Femtosecond Laser Drilling
Lasers naturally exhibit Gaussian beam characteristics, which tend to cause natural taper due to exit energy attenuation. Through professional beam shaping technology and process path optimization, we can minimize taper and precisely machine zero-taper holes, positive taper holes, and reverse taper holes in materials up to 2mm thick, compatible with almost all materials including metals, plastics, and ceramics.
Special-Shaped Zero-Taper Holes
"Zero-taper holes" refer to holes where the wall is completely perpendicular to the material surface, with consistent inlet and outlet diameters. As precision fluid/gas transmission channels, hole taper directly affects flow rate, pressure, and reaction efficiency.
Core application scenarios of zero-taper holes include: GDI engine injectors in the automotive industry, microfluidic chips, drug delivery devices and implantable sensors in medical devices, Probe Card microholes in semiconductor testing (R angle ≤ 4μm), and special fiber spinneret microholes in high-end textiles.

Reverse taper holes are mostly used in scenarios requiring improved fluid passage rate or reduced surface friction:
•Aerospace：Reverse taper holes in cooling systems can enhance fluid circulation efficiency and improve thermal management performance;
•Biomedical：Reverse taper holes in implantable devices reduce tissue friction, with controllable taper and processable inlet/outlet radii. Surface quality reaches Ra0.4, with no burrs or chipping
10:1 Aspect Ratio Taper Holes
Utilizing the natural taper characteristic of laser drilling, taper holes with an aspect ratio of 10:1 can be processed.
With inherent flow guidance, they are suitable for scenarios requiring directional fluid transmission.

Array drilling, which creates hundreds to thousands of microholes in thin materials, is widely used in various filtration scenarios: cell sieves, liquid screens, printer inkjet plates, automotive injection nozzles, semiconductor wafer stepper air filters, aircraft oil filters, etc. Femtosecond lasers enable ultra-high-density, high-quality screen processing with key parameters as follows:
•Machining Precision: ±1 μm
•Positioning Precision: ±1 μm
•Drilling Diameter Range: 3µm - 100µm
