C3 Laser

Applications

Laser marking is the most flexible type of direct part marking available today! The ability to change various laser parameters offers users the ultimate in control, quality and speed versus competitive marking technologies. C3 Laser’ Fiber Laser Marking Systems utilize the latest advancements in laser-based material processing.  They offer significant advantages over solid state Nd:YAG lasers and have the ability to mark a wide variety of materials using different techniques.

Our system is able to produce a mark with the following techniques:

  1. Surface Etching:  A surface etch usually gives a bright contrasting mark. It is ideal for marking on coatings without penetrating through, such as Chrome, Nickel, etc. 
  2. Surface Annealing: Most common when marking on stainless steel.
  3. Ablation: The ability to remove surface treatments (i.e. Coatings of paint) to create high contrast without damaging the base material – widely used in backlit material processing, such as backlit buttons.
  4. Paint Removal: The process of burning or vaporizing the a coating of paint that is either on metal or plastic. Most common for backlit buttons.
  5. Engraving: The process of vaporizing a material to dig into the part.
All of our Fiber Laser Marking Systems feature the ability to mark Alphanumeric characters, Linear Barcodes, 2D Symbologies such as Data Matrix Codes, Schematics, Logos, Serial Numbers, Lot Codes, Security Codes, Graphics, OCR Codes and more.

Quartz Welding
Quartz glass carriers, wafer boats, windows, diffusion oven tubes, and domes used in semiconductor industry can now be welded quickly and efficiently.

Weld quality is greatly improved and well controlled. Defective components are virtually eliminated leading to greatly reduced production costs.

Mirrors
Mirrors used in telescopes and astral-physical devices can now be structurally welded to virtually any shape or size. Previous size limitations of 5 meters no longer apply as a result of the very low stress incurred in the welding and the high quality of the joint.

Camera Lenses
Components such as camera lenses are at present welded by the flame method. The quality of the weld is poor since the weld is built up slowly layer by layer and severe optical dislocations are present in the lens "window" area around the weld edge. Our technique has been used to greatly improve the effective lens aperture by eliminating these dislocations.

Multicoat Panel Paint Removal
Excellent results were achieved with the Q-switched Fiber laser on backlit and radio buttons for a variety of automotive applications. High brightness and contrast are typical for dark paint removal from multilevel paint on clear acrylic. The uniqueness of the fiber laser for this specific application is that the Fiber Laser completely replaces the Green beam while adding unmatched reliability and simplicity to the process.

The paint was removed from the plastic parts using a Fiber Laser Marking System. Several different laser parameters were tested and were able to completely remove the paint. The move delays and the focal distance were optimized in order to produce a more uniform paint removal without causing any melting of the plastic.

Metal Surface Marking & Etching
Useful for component identification, bar-coding, inventory, and others, the Fiber Laser provides quick and maintenance-free solutions for the growing demands of the automotive and aerospace industries.

Flat Panel Display
Cutting materials: LCD Glass, CF
Product: 17” TFT LCD, 2 x 0.7 mm
Type of Laser: CO2 300 Watt
Laser power used: 180 Watt
Cutting Speed: 400 mm/sec for TFT and 500mm/sec for CF side.

From CF side 16” TFT LCD, 2 x 0.7 mm were cut on with combined scribe/break method in one pass. The TFT side was scribed but not broken. Breaking of the TFT side was done on a stand along the breaker to achieve final separation of the panel. ITO coated and Chromium Coated glass was scribed from the glass side and broken manually.

Glass Dicing
Cutting materials: Glass
Type of Laser: Fantom™ Laser 250GL

With exposure in Biometric ID devices it became necessary to find a method of precision separating of glass panels into individual components without generating any debris on the glass surface.

TFT Panels
Cutting materials: 2 x 0.55 mm (and 0.55 + 0.7 mm) Glass
Product: 17” TFT LCD, 2 x 0.55 mm
Type of Laser: Fantom™ Laser 250GL
Cutting Speed: 600 mm/sec for TFT

Small TFT panels for Cellular Phone Application. Full separation with extremely high quality corners was achieved.

Marking and Stainless Steel
Cutting materials: Stainless Steel
Type of Laser: Q-Switched Fiber Laser
Laser Power Used: 20 Watts

The parts were marked using 420 mm focal length lens and a working distance of 493 mm. The parts were surface annealed to create a contrasting mark. The parts were marked at a frequency of 40kHz at a speed of 5 inches per second, using approximately 16 watts of power.

Etching and Annealing on Steel Tools
