Because the RFH UV laser demonstrated excellent performance in terms of stability, the customer decided to sign a long-term cooperation contract with it. RFH UV laser S9 will be widely used for high-precision marking of text, patterns and other information on various medical devices and pharmaceutical packaging.

During a recent visit, our customer got to know RFH in depth and was attracted by the outstanding performance of our high-power UV laser Expert III 355. After careful consideration, they decided to purchase this device and apply it to various information markings on printed circuit boards (PCBs).

Recently, an old customer from Spain once again purchased RFH's Exper III 355 high-power UV laser. This is the second time they have purchased RFH's laser. This not only reflects customers' recognition of RFH products, but also highlights RFH's excellent quality and performance in the laser field.

RFH D9 series Water cooled UV laser's power is 3w .Comparing with its kinds, D9 series UV laser features with rugged sealed cavity, extremely compact size, simple and robust, high stability, high efficiency, high reliability and excellent laser beam quality.Its compact design suggests no necessity in building big light path, which greatly reduces space and cost and makes it easy to be installed into UV laser marking machines. In addition, D9 series cavity structure has more stability and more excellent scalability, which means the same laser cavity can produce multi-power lasers , and the stability of different power ranges is greatly improved.

In recent years, with the continuous development of science and technology, low-power 5W ultraviolet lasers have become more and more widely used to blacken PCB circuit boards. This technology can effectively concentrate the laser energy in a small area, causing the temperature of the area to rise rapidly, achieving the effect of instantly melting and vaporizing the copper foil on the PCB circuit board. Below, this article will introduce in detail the application of low-power 5W ultraviolet laser to blacken PCB circuit boards from several aspects.

UV lasers, especially those with 10W power, have been widely used in various industrial applications. In addition to marking and engraving on a variety of materials, this laser can now also cut thin metals.

Copper foil is also one of the common components in electronic applications. It is a cathodic electrolytic material and a thin, continuous layer of metal foil deposited on the base layer of the circuit board. It serves as the conductor of the circuit board. Copper foil is a very thin copper product. The thickness of paper-like copper is expressed in microns. Generally between 5um and 135um, the thinner and wider it is, the harder it is to produce. Simply put, copper is pressed into very thin sheets, which is copper foil.

Leather is a widely used material and is also synonymous with high-end. It is often used to make clothing, shoes and hats, bags, furniture and other products. Leather has the characteristics of soft texture, durability, and beauty. Leather marking is to engrave text and patterns on the surface of the leather, which is not only personalized but also promotes the brand.
