Introduction
Marking size : stardards marking size 200*200mm.
Keyboards transparent marking application adopted 200*200mm marking len or 175*175mm marking len.
Keyboards general marking use 300*300mm marking len.
It adopted infrared laser source which is special designed and produced for the high precision non metals and metals laser marking application.
Sophisticated resonant cavity design, and adopt of international first-line brand of laser devices, so that the laser is more stable,multi-parameter adjustment to meet a variety of processing needs.
Infrared – Laser source
Application advantages
Ultra high pulse stability and power stability.
Superior beam quality.
Arbitrary switch between pulse and continuous modes of operation.
No material selection, multiple colors keyboards can be marked.
The marking of pervious to light products（transparent process by laser） is one of the most difficult applications in laser industry. Some domestic companies have become famous enterprises just because they master this application. This technology has been transferred from the automobile industry to the 3C industry. Electronic products such as light-transmitting keyboards, electric toothbrushes and routers have been used and will be more widely used in the future.
For example
Transparent Laser Process
What is the difficulty of pervious to light products?
As shown in the figure, the product has at least 2 layers of paint, each layer of paint thickness is only a few microns. It is necessary to control the laser to cut off the black paint on the surface and leak out the red paint and blue paint below without damaging the paint layer below, and ensure the edge is neat and the color is bright.
This requires very high laser, not only the laser can adjust the power, frequency, pulse width and other parameters (most lasers cannot adjust the pulse width), but also very high power stability, pulse stability (all less than 3%), extremely superior beam quality (<1.3).
Which lasers are used to do transparent process ?
(Infrared Laser )Q-switched end-pump laser is the most suitable, with a wide processing range, and can be processed with different colors and thickened paint layers.
The MOPA fiber laser has a narrow processing range and is only suitable for black coatings fine .And others color and coating not good enough.
