15W UV laser cold processing marking pcb circuit board QR code

Early in the morning, I communicated with a customer for more than a month and returned an order contract to purchase 5 15W ultraviolet lasers at a time for the laser marking of two-dimensional codes on pcb circuit boards.

Thank customers for their support and trust in RFH.

Ultraviolet laser is a short-wavelength laser. Generally, frequency doubling technology is used to convert the infrared light (1064nm) emitted by the solid-state laser into 355nm (triple frequency) and 266nm (quadruple frequency) ultraviolet light. The photon energy is very large, which can match the energy levels of some chemical bonds (ionic bonds, covalent bonds, metal bonds) of almost all substances in nature, and directly break the chemical bonds, causing the material to undergo photochemical reactions without obvious thermal effects (nucleus, Certain energy levels of the inner electrons can absorb ultraviolet photons, and then transfer the energy through the lattice vibration, resulting in a thermal effect, but it is not obvious), which belongs to "cold working". Because there is no obvious thermal effect, UV laser cannot be used for welding, and is generally used for PCB circuit board marking and precision cutting.

The wavelength of the ultraviolet laser generator is 355nm, the light quality is high, the focal spot is very small, it belongs to the cold light source and the processing heat hazard zone is small, so it can carry out ultra-fine marking and material marking, which has a higher actual marking effect. The specified customer preferred product.

In 13 years of technical strength accumulation, the power of RFH UV lasers has been increased from 3W-5W to 8W, 10W, and 15W to meet market development needs. The substantial increase in power has doubled the processing performance. Next, the RFH Laser Editor will introduce to you how powerful a 15W UV laser is. Take our Expert III 355 ultraviolet pulsed solid-state laser as an example:

The Expert III 355 series ultraviolet laser with a power of 15W can quickly cut, scribe, perforate PE, PCB, FPC, glass, sapphire, ceramics and other non-metallic materials, and can achieve ultra-fine processing effects, such as not burning Edge, non-carbonization, low thermal effect, and unique Q-switching control technology, which can be suitable for various laser application control needs, so it is evaluated as a "high-precision laser processing master" by domestic and foreign industry users!

The excellence of this RFH laser comes from many aspects:

All Expert III 355 UV laser products are produced in strict compliance with the "Quality Management System" regulations

From procurement-pre-production quality inspection control-rigorous assembly process-finished product testing-warehousing quality inspection-pre-delivery inspection-after-sales service, each level is checked to ensure stable quality and consistency of equipment parameters with actual operating parameters. This is the reason why the service life of RFH brand lasers is better than that of peers

Expert III 355 UV laser is produced in a dust-free workshop

The clean production environment ensures that all electronic components are produced dust-free and free from pollution.

A team of professors at home and abroad independently developed the Expert III 355 UV laser dedicated power supply control system. The power supply and the laser have a one-to-one correspondence. The stability of the power supply control system determines whether the laser can maximize its performance during operation. RFH has the advantages of independent research and development of power supply technology, which can update the function modules of the power control system in time, and improve the function modules according to the needs of the laser. 13 years of R&D technology accumulation, domestic and foreign professors, doctoral level R&D team. This is a solid backing for the stable operation of RFH's entire laser system.

 Power supply + laser head + cooling system, complete system sales From the user's point of view, RFH has launched a complete laser system sales program to ensure the stability of the entire laser system and maximize its performance

The Expert III 355 ultraviolet laser adopts a fully digital display, supports communication with a computer, and can remotely monitor the laser. The integrated compact design facilitates equipment integration.
