Fiber laser cutting pcb.

A 20 watt fixed pulsewidth fiber laser will approaches 1mj of energy per pulse at a pulsefrequency of about 20 khz and 20 watts of output power. Fiber lasers are able to cut through thick exotic metal alloys with laser precision and cleanliness. Back to tutorial index. Wuhan hglaser engineering co ltd.

For plates with a thickness of up to 4mm nitrogen can be used as the gas for high pressure cutting. The fiber laser enables us to engrave the copper layer of the fr1 and once it has been removed we can cut the board with the co 2 laser. Analysis of laser cutting materials fiber laser cutting effect structural steel. Laser cutting a pcb with a co 2 fiber trotec laser cutter introduction.

Laser processing fr 4 g10 is possible with a 9 3 or 10 6 micron co 2 laser with no significant difference between the quality produced by the two wavelengths. Laser cutting a pcb with a co 2 fiber trotec laser cutter. Welcome to buy high quality laser equipment for sale here from our factory. 2 marking graphics text on pre made pcbs.

Best type of laser for this appliation. The 1 06 micron fiber laser is not used for cutting this material as the wavelength is not readily absorbed. The material will get better results when it is cut with oxygen. Laser etching pcb s was also of interest to me as i was hoping to get rid of the messy fecl3 etching but cutting that copper would require quite a bit more power i understand.

When oxygen is used as a processing gas the cutting edge is slightly oxidized. For price consultation contact us. Because of this a 20 watt fixed pulsewidth fiber laser is not allowed to work at pulse frequencies lower than 20 khz. We re well known as one of the leading laser cutting machine laser marking machine laser welding machine laser cleaning machine laser tube cutting machine manufacturers and suppliers in china.

Testing a fiber laser that is used for engraving anodized aluminum surfaces as a pcb prototyping tool. They extend the benefits of laser cutting to a whole new range of materials. 60 watt co 2 laser 30 watt fiber laser. Fixed pulsewidth fiber lasers have a damage threshold of about 1mj of energy.

Works great if you get the settings right but usually the pcb epoxy laminate gets charred.
