Although soon lasers and continuous (CW) lasers can also be used for engraving applications, more or nanosecond pulsed fiber lasers are used. The nanosecond laser pulse is short and the maximum power is high, especially when it is suitable for PCB laser engraving. high quality gas filter

The design of the power supply circuit (MOPA) of the main fluctuating power amplifier circuit allows customers to easily and happily choose the pulse width, and the constant frequency can reach 4MHz. For example, SPI Laser's Pulse Tuning (PulseTune) professional, can make the pulse width adjustable in the range of 3ns~2μs, which provides customers with the opportunity to improve the pulse characteristics, thereby improving the quality or efficiency of laser engraving. high quality laser engraver fume extractor

The laser can engrave on the copper surface. An energy-saving manufacturing process application (nanosecond pulsed laser) is to engrave a printed circuit board (PCB) on a copper sheet, and the traditional method is based on chemical corrosion to cause a complex conductivity method. The copper layer is relatively thin, generally 40~100µm thick, but the metal composite layer can be easily removed according to the engraving expertise to expose the FR4 sheet. Like the VIN logo example, changing the basic parameters of the laser can remove all remaining debris on the FR4 monocrystalline silicon wafer. In addition, the laser can also cut the copper sheet into the required specifications. Although laser-engraved pcb circuit boards are not suitable for mass production, they can be used for rapid production of PCB prototypes. high quality laser fume extractor
