High power nanosecond UV laser and green laser cutting PCB board Cutting PCB circuit boards, is it better to use a UV laser or a green laser?   PCB panels are often used to carry hardware with electronic chips. Under the current situation that the price of electronic chips continues to rise, how to make PCB panels into more practical and precious electronic chips has become a very important issue.

The high power UV laser is 355 nm wavelength, with a "cold marking" method, the laser beam diameter is only 20 μm after focusing, the UV laser's pulse energy comes in contact with the material in the microsecond. There is no significant thermal influence next to the slit, so no heat damages the electronic component.  

High power industrial uv laser cut pcb board Expert III 355 series UV DPSS laser, developed and produced by RFH, covers 10w-15w in laser power with short pulse width (<20ns@40K) ,superior beam quality (M²<1.2) and perfect laser spot quality (beam circularity >90%). It is widely used in PE/PCB/FPC cutting, glass & sapphire cutting, drilling, scribing & cutting used in high precision micromaching areas.

A major electronics factory in Dongguan recently ordered two 20w high-power UV lasers from RFH to cut PCBs of different sizes. Before that, they had already ordered a UV laser from RFH. According to Mr. Chen, the high power output of the RFH UV laser drives the cutting speed and makes it ideal for production on the fly.

UV laser cutting is a precise and efficient method for cutting PCBs. To use a UV laser to cut a PCB, you will need a UV laser cutting machine and a CAD file of the PCB design. Here are the basic steps for using a UV laser to cut a PCB:
