Although extremely fast lasers and continuous (CW) lasers can also be used for engraving applications, more or nanosecond pulsed fiber line lasers are used. The nanosecond laser pulse is short and the maximum output power is high, which is especially suitable for PCB laser engraving. soldering dust extractor

The design scheme of the main oscillating power amplifier circuit (MOPA) allows consumers to choose the pulse width easily and freely, and the repetition frequency reaches 4MHz. For example, the pulse tuning technology of SPI laser company can make the pulse width adjustable within the range of 3ns~2μs, which brings customers the opportunity to improve the pulse characteristics, and then enhance the quality or high efficiency of laser engraving. trumpf laser cutting machine dust collector

The laser can carry out engraving on the copper surface. An environmentally friendly processing technology (nanosecond pulsed laser) is to engrave printed circuit boards (PCBs) on copper foils, while the traditional method is to create complicated conductive pathways based on chemical corrosion. The copper layer is relatively thin, generally 40-100µm thick, but the metal material layer can be easily removed according to the engraving technique, exposing the FR4 substrate. As in the case of the VIN logo, changing the main parameters of the laser can eliminate all remaining debris on the FR4 silicon wafer. In addition, the laser can also cut copper sheets into required specifications. Although laser-engraved circuit boards are not suitable for mass production, they can be quickly manufactured using PCB prototypes. vacuum fume extractor for laser machine dongguan
