UV Laser Marking Machine for High-Tech Precision Materials

UV laser marking machines are ideal for marking high-tech precision materials due to their cold processing capabilities and high resolution. Here's what you should know:

Key Advantages for Precision Materials

1. Cold Marking Process: The 355nm UV wavelength causes minimal heat affectation, preventing material deformation or property changes.

2. High Resolution: Capable of producing marks with extremely fine details (down to 10μm), crucial for micro-components.

3. Non-Contact Processing: Eliminates mechanical stress on delicate materials.

Suitable Materials

• Semiconductors: Silicon wafers, IC chips

• Advanced Polymers: PI, PET, PEEK

• Medical Components: Implants, surgical tools

• Precision Optics: Lenses, filters

• Electronics: PCB, FPC, ceramic substrates

• Specialty Metals: Thin foils, coated materials

Technical Specifications

• Laser Type: Typically 3-5W UV DPSS laser

• Spot Size: 10-30μm

• Pulse Width: <30ns

• Marking Speed: Up to 7000mm/s

• Positioning Accuracy: ±0.001mm

Applications

• Micro QR codes for traceability

• Serial numbers on medical devices

• Branding on delicate components

• Anti-counterfeit markings

• Precision alignment marks

Considerations for Optimal Results

1. Material Testing: Always conduct preliminary tests to determine optimal parameters

2. Focus Control: Maintain precise focal position for consistent marks

3. Clean Environment: Prevent contamination of sensitive surfaces

4. Parameter Optimization: Adjust frequency, speed, and power for each material
