355nm UV laser etching PCB/FPCB circuit board

Ultraviolet laser can mark various characters, symbols and patterns on the surface of circuit board PCB/FPCB, and the character size can range from millimeters to micrometers. In addition to effective anti-counterfeiting, it can also realize the control and traceability of product quality. Whether it is fine processing or processing efficiency, it fully meets the current needs of PCB/FPCB marking processing.

On Monday morning, I received a customer from Jiangsu who needed to purchase a 355nm UV laser for PCB/FPCB marking processing. The customer said that he originally used a certain brand of laser on the market, but soon discovered that the light intensity was indicated during the use of the ultraviolet laser, and the workpiece was burned. He asked us what solution could be provided.

In fact, the design of each brand laser is different. If it is an RFH EXCELLENT series laser, you can change the "laser mode" parameter value to "Hold" mode; if it is an EXPERT series laser, you can increase the "QS low power" value to reduce the indicator light. If the laser is unstable after the indicator light is weakened, the internal control mode optimizes the LBO temperature to increase the power, and the LD temperature to increase the power. If it doesn’t work, it can only be returned to the factory for repair.

However, in addition to the above-mentioned problems, the lasers currently used by the customer also have power attenuation, so he decided to purchase 5 new 355nm ultraviolet lasers at RFH.

For the PCB/FPCB marking processing industry for 13 years, the Expert III 355 series of UV diode pumped pulsed solid-state lasers developed and produced by RFH have a power range of 10W-15W, using a unique laser cavity design, acousto-optic Q-switching technology, and high The precision cooling system, small size, and high integration have established an excellent brand image in the field of PCB/FPCB engraving QR codes.

The Expert III 355 high-power UV laser has a short pulse width (<20ns@40k), so during processing, the heat-affected area is small, and it is not prone to scorching and deformation; it is strictly guaranteed in all frequency ranges. Beam quality (M²<1.2) and perfect spot characteristics (spot ellipticity>90%); The inner cavity has a self-purification system, which makes the laser long life and stable operation; RFH design and production of UV lasers are controlled by a fully digital intelligent power supply Technology, simple operation, convenient monitoring, also supports communication with the computer, and can control the laser externally through RS232; integrated design, convenient equipment integration.

As we all know, there is a one-to-one correspondence between the power supply and the laser, and the stability of the power supply control system determines whether the laser can maximize its performance during operation. RFH has the advantage of independent research and development of laser dedicated power control system, which can update the power control system functional modules in time, and improve the functional modules according to laser requirements. This is also one of the reasons to ensure high power stability and long life of RFH lasers.

13 years of development and precipitation, RFH research and development, each laser product produced can maintain consistent stable quality, constant beam quality, high-efficiency power consumption under extreme industrial and scientific research conditions, with excellent cost performance and high reliability. It has won high recognition and a good reputation from users in all walks of life at home and abroad.
