Aluminum Oxide sheet surface stripping application
Now the more the electronic products become thinner, many mobile phones, tablets, computers are using a lightweight alumina as a product shell. Using the Q-Switch Laser to mark the conductive position on the thin aluminum plate.It is easy to cause material distortion, and the back produces the ” convex package “. Directly affect the appearance of aesthetics. The use of the MOPA laser small pulse width parameters. That can make the material difficult to deformation, shading also more delicate bright white. This is because the MOPA Laser uses a small pulse width parameter to allow the laser to stay in the material for a shorter period of time. And has high enough energy to clear the anode layer,so for the thin alumina plate surface stripping anode processing, MOPA lasers are a better choice.
Anodized Alumina application
use lasers to mark Black trademarks on the surface of anodized alumina materials, model, text and so on. The application in the last two years gradually by Apple, Huawei, ZTE, Lenovo, and other electronic manufacturers widely used in electronic products shell, used to mark the black mark, model and so on. For this type of application, only MOPA lasers are available for processing. Because the MOPA Laser has broad pulse width and pulse frequency regulation range, using narrow pulse width. High frequency parameters can be marked on the surface of the material black effect, through different combinations of parameters can also be marked with different grayscale effect.
Electronics, semiconductors, TO precision machining Applications.
So if you need to mark on some precision objects,MOPA is better.
There is no any touch feeling.There is no any burning trace.And also permanent marking.
