PCB laser engraving: laser co2 smoke purifier is needed to make circuit boards with laser engraving body

New technology and new process improve the productivity of PCB laser engraving and ensure the quality

The laser can carry out engraving on the copper surface. A new type of processing technology (nanosecond pulse laser) is to engrave a printed circuit board (PCB) on a copper sheet, and the traditional method is to create a complicated conductive path based on chemical corrosion. The copper layer is relatively thin, usually 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. laser co2 fume extractor for cleaning equipment

Laser engraving is essentially material removal, and the entire process of a laser effect removes only tens of microns in depth. Therefore, the entire process of material removal is relatively slow. The removal rate achieved at this stage is measured per cubic millimeter, and the high removal efficiency is determined by the average power. To complete high-quality laser engraving and high-efficiency material removal at the same time, the most important thing is to choose an improved processing plan. Because grating ruler scanners usually produce furrows, there are problems such as low depth removal and residual surface roughness. Therefore, unless the engraving regulations are not high, this type of processing technology is generally not recommended. laser co2 fume extractor for southeast asia
