RFH green laser is used in PCB circuit board laser cutting, depaneling

UV Laser Diode cutting PCB with reduced thermal damage

PCB, or printed circuit board, a tiny electronic circuit. Its development history in our country is mainly in the past ten years. Coincidentally, RFH Laser was also established at that time. For more than ten years, the market demand for PCB circuit boards has been rising, whether it is front-end mobile phones, tablets, terminal routers, base stations, or back-end supercomputers. Along with the increase in quantity demand, there is also technical demand. It is obvious that the volume of PCB circuit boards is getting smaller and smaller.

However, the smaller the size of the PCB circuit board, the more difficult it is to process, and the price of PCB circuit boards in my country is still low, which requires manufacturers to continuously improve manufacturing technology to improve product performance and production efficiency, so as to maintain market competitiveness.

Cutting technology is one of the technologies that most PCB circuit board manufacturers want to improve. Currently, UV lasers and green lasers are the mainstream cutting equipment. However, the brands of lasers used by manufacturers are not the same, which is why some circuit boards look rough, while others look finer. There are many rough processes, but the fine ones must be top-notch.

A factory in Dongguan has first-class craftsmanship. The factory used 5 fully automatic PCB circuit board laser splitters, and purchased 5 RFH high-quality green pulsed solid-state lasers for the first time in cooperation. RFH high-quality green pulsed solid-state laser has excellent beam quality (M2<1.2) and pulse width <12ns@40k, which are strictly guaranteed in all frequency ranges. Therefore, the heat-affected zone during processing is very small, and the cut PCB The circuit board is neat and free of burr, no burning, no black edge, easy to mass produce fine finished products.

In addition to cutting PCB circuit boards, the 35W green pulsed solid-state laser can do more things, because it has a unique Q-switching control technology developed by RFH's top laser R&D team composed of professors and doctors from Tsinghua University. Laser application control needs, and it is an all-in-one design, which is convenient for equipment integration.

Los láseres de primer nivel son desarrollados y fabricados por empresas de primer nivel. Desde el control de inspección de calidad de adquisición y preproducción, hasta el riguroso proceso de ensamblaje, las pruebas de productos terminados, la inspección de calidad de almacenamiento y luego la inspección previa a la entrega y el servicio posventa, verificamos en todos los niveles para garantizar una calidad estable y consistencia entre los parámetros del equipo. y parámetros operativos reales. RFH muestra a los usuarios de la industria lo que es la máxima calidad.
