The application of 20w uv laser in electronic products

In the manufacturing process of electronic products, laser technology is widely used, from the internal circuit boards, ICs, screens, connectors of electronic products to external power lines, data lines, plastic or metal shells, etc.

A good UV laser marking machine, as a rookie in the laser industry, has emerged in the electronic product manufacturing industry in the past two years. Gradually complete the replacement of fiber laser marking machines;

The reason why UV laser marking machine is more and more widely used in the electronic product manufacturing industry mainly comes from its technical advantages:

uv laser | green laser | Ultraviolet lasers | uv dpss laser | nanosecond laser | UV laser source | Solid State Lasers

The wavelength of the ultraviolet laser beam is in the 355nm band. The laser beam in this band has strong energy and low heat. When processing workpieces, the ultraviolet laser generates much less heat than the fiber laser in the near-infrared band and the carbon dioxide laser in the far-infrared band. When the metal sheet is used, the metal sheet processed by the UV laser marking machine will not be deformed due to excessive heat; at the same time, the high energy characteristics of the UV laser beam also make the UV laser marking machine suitable for stripping the surface coating of materials;

Most of the electronic product marking applications that ordinary consumers can see daily come from the plastic shells, adapters or data cables of electronic products, such as: trademarks, logos, specifications and other information on products such as power banks, plugs, earphones or adapters In the past, such plastic products were generally printed with ink or processed by fiber laser marking machines; fiber laser marking machines have extremely high requirements on the material of plastics when processing plastics, because some plastics are processed by fiber lasers at 1064nm. The foaming and carbonization effects of the wave band lead to uneven plastic surface after laser processing, and at the same time, the plastic color changes unevenly, and there are many explosion points; such a marking effect greatly affects the brand image of the product;

The 355nm UV laser processing is different. Almost all plastic materials have good laser absorption characteristics in the 355nm band, which makes the UV laser marking machine do not choose materials when marking plastic products, regardless of the composition of the material. The marking machine can mark the plastic shell and the sheath layer of the data cable with high contrast, delicate and smooth marking effect, which can greatly improve the perception of the product brand image; at the same time, because the UV laser marking machine does not choose Plastic materials, so for most cost-conscious electronics manufacturers, it also makes it possible to use cheaper materials to make products, for example: better PC materials on the market are several thousand more expensive than poor quality materials The same is true for HDPE materials; and the UV laser marking machine can print good results on any material.
