Mopa Laser Marking Machine in Alumina Sheet Surface Stripping Application
Nowadays, electronic products are getting thinner and thinner. Many mobile phones, tablets and computers use thin and light alumina as the outer shell of the products. When using a Q-switched laser to mark conductive potential on a thin aluminum plate, it is easy to cause deformation of the material and produce a “convex hull” on the back, which directly affects the aesthetics of the appearance. The parameters of the MOPA laser with a smaller pulse width can make the material not easily deformed, and the shading will be more delicate and brighter. This is because the MOPA laser uses a small pulse width parameter to make the laser stay on the material shorter, and the energy is high enough to remove the anode layer, so for the process of stripping the anode on the surface of the thin aluminum oxide plate, MOPA Lasers are a better choice.

Advantages of mopa laser marking machine
1. Flexible control, independent adjustable pulse width and frequency
2. Pulse shape controllable
3. Large adjustable range of parameters
4. Strong system upgrade ability
Use laser to mark black trademark, model, text, etc. on the surface of anodized aluminum material. In the past two years, this application has gradually been widely used by electronics manufacturers such as Apple, Huawei, ZTE, Lenovo, etc. for the shell of electronic products , used to mark the trademark, model, etc. of the black mark. For such applications, currently only MOPA lasers can process them. Since the MOPA laser has a wide range of pulse width and pulse frequency adjustment, the parameters of narrow pulse width and high frequency can be used to mark the black effect on the surface of the material, and different gray scale effects can also be marked by different parameter combinations.

Why Mopa can mark color on metal, whats the difference with normal fiber marker ?Generally, the pulse width of laser marking machine is fixed, the range is about 80-120ns, and the frequency is 20KHz-80KHz
MOPA laser marking machine (take IPG’s 20-watt as an example) has an adjustable pulse width of 2-200ns and a frequency of 1.6KHz-1000KHz. The MOPA laser marking machine has many pulse widths and a wide frequency range, so there are many combinations of various parameters, which can There are many kinds of effects, and there are many suitable materials and products. The function of stainless steel color marking and aluminum black marking is also one of the main functions of mopa laser marking machine.
