Alumina/Aluminum oxide sheet surface stripping application:
Nowadays, electronic products are getting thinner and lighter. Many mobile phones, tablets, and computers are using thin aluminum oxide as the outer casing of the product. When the Q-switched laser is used to mark the conductive position on the thin aluminum plate, the material would easily get deformed, which directly affects the beauty of its appearance.
Mopa laser has smaller pulse width which can get less deformed result and the shading is more delicate and bright. Because MOPA laser uses a small pulse width parameter to make the laser stay in the material for a shorter time, and has enough energy to remove the anode layer. Therefore, for the processing of stripping the anode of a thin alumina plate, MOPA Laser is a better choice.
Anodized aluminum blackening application:
Marking black trademark, model, text, etc on the surface of the anodized aluminum material is widely used in electronic manufacturers such as Apple, Huawei, ZTE, Lenovo, etc in the past two years. For this type of application, MOPA lasers will make an excellent result. Because MOPA laser has a wide pulse width and pulse frequency adjustment range, thus the parameters can be adjust with narrow pulse width and high frequency to achieve black result on surface and the different gray scale effects can be marked by different parameter combinations.
Electronics, semiconductor, ITO precision processing applications:
In precision machining field, such as electronics, semiconductors, and ITO, it is often necessary to use fine scribing applications. Due to its own architecture, the Q-switched laser cannot adjust the pulse width parameter, so the line drawn is difficult to be fine. The MOPA laser can flexibly adjust the pulse width and frequency parameters, which not only makes the line drawn fine, but also the edges appear smooth and not rough.
The main advantages for mopa as follows: (Normal function for Mopa, use JPT laser source LP+)
1. Alumina/Aluminum oxide sheet surface stripping application;
2. Anodized aluminum blackening application;
3. Electronics, semiconductor, ITO precision processing applications.
It not means Q switched cannot have same function, but means MOPA made better result than Q switched.
Meanwhile, Mopa laser source has extra function that is color marking on stainless steel.
