In the realm of product identification, the importance of clear and precise markings cannot be overstated. In particular, the ability to mark transparent plastic materials has become a crucial requirement for various industries. Enter the awe-inspiring world of 5W UV laser module marking, where technology meets elegance to create indelible impressions on transparent plastic surfaces.  

In recent years, with the continuous development of technology, ultraviolet lasers have been widely used in many fields. One application is black lettering on yellow heat shrink tubing. This technology is widely used in various industries such as electronics, communications, medical and military.

First of all, the ultraviolet laser is a high-energy laser beam with a wavelength range of around 355nm and has the characteristics of high precision, high speed and high efficiency. In the field of 3D printing, UV lasers are mainly used to solidify liquid photosensitive resin to form a solid laminated structure. Among them, 3W and 5W ultraviolet lasers are two common power specifications, which refer to the laser output power of 3 watts and 5 watts respectively.

RFH F9 series Water cooled UV laser's power range is 3w-5w .Comparing with its kinds, F9 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, F9 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.

Specializing in the field of high-precision processing, EXPERTIII 355-15-50 series lasers to provide you with a comprehensive and high-quality solution. Whether it is PE/PCB/FPC cutting, or glass, sapphire cutting, or high-definition micro-processing of drilling, marking, cutting, etc. , our laser can meet your needs. Our laser uses an efficient wavelength of 354.7 nm, covering a wide range of repetitive frequencies (10 khz to 200 khz) . Regardless of your application scenario, we provide excellent beam quality (m & LT; 1.2) . Moreover, we guarantee the consistency of beam quality in all frequency range. To minimize the heat-affected region, our laser uses a pulse width of less than 20ns@40k. This means that even at high frequencies, the processing is still excellent. In addition, we also use a unique q-switched control technology to meet the needs of various laser applications, in order to ensure the long life and stable operation of the laser, we also use the internal cavity self-purification system. This makes our laser not only long life, but also stable and reliable operation, in order to facilitate the operation and monitoring, we use the digital intelligent power control technology. This makes your operation easier and allows you to monitor the status of the laser in real time; in addition, our laser also supports communication with the computer and can be controlled externally through the R5232. This gives you more convenience and flexibility in your work. Our EXPERTIII 355-15-50 laser uses an integrated design to provide you with convenient equipment molding. Whether it is a small studio or a large production line, our laser can be perfectly adapted to help you achieve better results.
