New green laser markers for faster semiconductor applications

PowerLine F QS green laser markers

The latest PowerLine F QS green laser markers deliver a 3X increase in available power for marking semiconductor integrated circuits and organic materials. The high-power air-cooled fiber laser delivers up to 27 W of output power in the green 532 nm wavelength. This is 3X more than existing PowerLine F QS laser markers, while retaining all the performance and software advantages associated with these earlier models.

The combination of short wavelength and short pulse width enables shallow marking of semiconductors and heat-sensitive plastics. For example, the pulse width is only 1.5 ns and the beam quality is very high at M2 = 1.5. Shallow penetration is a particularly important requirement in most semiconductor marking applications because it eliminates the risk of photothermal damage to the underlying circuitry. The high quality circular beam allows for precise focusing that provides accurate marking with maximum contrast and clear, high resolution features. These excellent laser output parameters also make these markers suitable for cutting thin films.

Other useful performance features include the ability to set the laser repetition rate from 10 kHz to 900 kHz and to vary the laser power from 20% to 100%. This versatility allows the same laser marker to be optimized for different tasks, increasing its value and return on investment in many applications.

In addition to a range of scanner options, the new PowerLine F QS models can be configured with additional hardware/software options including "SmartMap3D" for freeform 3D marking. This option combines dynamic 3D focusing technology with 3D machine vision and powerful marking software. It is an easy-to-use technology solution that eliminates the cost and time of implementing specialized precision tools and simplifies the setup of the entire marking process. Additional software capabilities include on-the-fly marking support.

The operation of all hardware and software is integrated and managed by Coherent Laser FrameWork, which simplifies the design of sophisticated markers and facilitates the use of variable data (e.g. bar and serial codes).
