With the continuous development of technology, PCB circuit boards have become an indispensable part of electronic equipment manufacturing. However, in the production process of PCB circuit boards, depaneling is an important link. Traditional depaneling methods mainly use mechanical cutting or stamping. However, these methods have some problems, such as inaccurate cutting and burrs. Therefore, finding a more efficient and accurate deboarding method has become a top priority. In recent years, the application of high-power UV lasers in PCB circuit board depaneling has attracted more and more attention. This article will focus on the application of RFH high-power ultraviolet lasers in PCB circuit board depaneling.
With the continuous advancement of science and technology, laser marking technology, as an efficient, accurate and flexible processing method, has been widely used in various industries. RFH high-power UV laser, as one of the laser marking technologies, has received more and more attention in the field of metal marking due to its unique advantages.
20w High power uv laser engraving metal . 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.
To meet the market demand, RFH newly developed S9 series solid state pulsed UV laser in 2020. Comparing with its kinds, S9 series solid state pulsed UV laser features more compact and delicate design with more stable laser output.Its compact design suggests no necessity in building big light path, which reduces space and cost to a great extent and makes it easy to be installed into flying laser marking machines. In addition, S9 series UV laser has more stable laser cavity of better extensibility, which means the same laser cavity can be made into lasers of different powers whose stability are greatly improved.
