Mopa Fiber Laser Marking Engraving Machine

MOPA fiber laser parameters can be adjusted in a wide range. Therefore, in addition to covering conventional nanosecond laser processing applications, it can also use its unique narrow pulse width, high repetition frequency, and high peak power to achieve some unique precision processing applications. for example:

Alumina Sheet Surface Stripping Applications

Today's electronic products are becoming thinner and thinner. Many mobile phones, tablets, and computers use thin and light aluminum oxide as the outer shell of the product. When using a Q-switched laser to mark conductive bits on a thin aluminum plate, it is easy to cause deformation of the material and a convex hull on the back; which directly affects the aesthetics of the appearance. The use of the parameters of the smaller pulse width of the MOPA laser can make the material not easily deformed, and the shading is more delicate and bright. This is because the MOPA laser uses a small pulse width parameter to make the laser stay in the material shorter, and it has enough energy to remove the anode layer, so for the processing of stripping the anode on the surface of the thin aluminum oxide plate, MOPA Lasers are a better choice.

Anodized aluminum black application

Use a laser to mark black trademarks, models, characters, etc. on the surface of anodized aluminum materials. This application has gradually been widely used in the casings of electronic products by Apple, Huawei, ZTE, Lenovo, Meizu and other electronic manufacturers in the past two years. On the top, it is 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 narrow pulse width and high frequency parameters can be used to mark the black effect on the surface of the material, and different grayscale effects can also be marked by different parameter combinations.

Color laser marking

Color laser marking is a new type of laser marking process. At present, this technology only has MOPA lasers to mark color patterns on metal materials such as stainless steel, chrome, and titanium. When coloring stainless steel materials, the color change of the surface layer of the material can be changed by adjusting the laser beam, so as to obtain decorative effects of different colors. For the stainless steel product industry, the color of the marking pattern can be added, and various edits can be made as desired. Character pattern, convenient and easy to operate: environmental protection and pollution-free; marking speed is fast, which can greatly increase the added value of stainless steel products and enhance the market competitiveness of stainless steel products. Add value to the product.

Electronics, semiconductors, ITO precision processing applications

In precision processing such as electronics, semiconductors and ITO, fine scribing applications are often required. Due to its own structural reasons, the Q-switched laser cannot adjust the pulse width parameters, so it is difficult to make fine lines. The MOPA laser can flexibly adjust the pulse width and frequency parameters, not only can make the drawn lines fine, but also the edges appear smooth and not rough.

MOPA laser marking machine is suitable for the fine marking process of metal and non-metal materials, such as laser engraving of digital product parts, mobile phone back cover, IPAD, aluminum blacking, mobile phone keys, plastic light-transmitting keys, electronic components, integrated circuits ( IC), electrical appliances, communication products, sanitary ware, tool accessories, knives, glasses and watches, jewelry, auto parts, luggage buckles, cooking utensils, stainless steel products and many other industries.
