It can be challenging to ensure you get the exact amount of copper exposure you need.īecause the CO2 lasers cannot directly etch metal or cut it, we don't recommend cutting PCBs with this type of laser. The laser, specifically the FiberMark and Fusion FiberMark systems, can etch away the surface material to expose the copper beneath however, even though it is exceptionally precise, there can still be trace amounts of PCB material left behind. The following PCB applications do not lend themselves to being completed using the laser. While some PCB applications are laser friendly, others are better suited to a different kind of technology. Because the layer is so thin, the fiber lasers can also cut through that material. Our fiber laser was also able to mark the same white layer, however did not result in as much contrast.ģ) Engraving Through PCB material to expose copper layer.Įpilog's FiberMark and Fusion M2 Fiber Lasers are able to engrave through PCB material to expose the copper layer underneath. This 2D data matrix code was processed using a CO2 laser from Epilog. The PCB to the right contains a white area of engineered plastics that works well for barcodes, QR codes, or in this case, data matrix codes. Many PCBs are designed with a variety of components. This is an application we would want to test with the PCB you will be using in our Applications Lab to make sure it fit your needs. When marking directly on a PCB we are able to achive a low-contrast mark with both our fiber and CO2 laser systems. If you are looking to mark a printed circuit board with a bar code, logo, or serial number, this is also possible with our laser systems.īest system for this appliation: CO2 Laser or Fiber Laser. While Epilog's CO2 systems will cut through the PCB as long as there is no copper layer, our fiber laser systems (the FiberMark 24 and Fusion M2 Fiber Laser) will cut through both with and without the copper layer.Ģ) Marking graphics/text on pre-made PCBs. Operators can use an Epilog Laser system to cut tabbed perforations around each board out so they can be easily removed from the sheet.īest type of laser for this appliation: Fiber Laser. The images below illustrate a sheet of already created circuit boards. CorelDRAW Questions - All Categories - Connect With Us Epilog Laser 16371 Table Mountain Parkway Golden, CO 80403, USA. Ideal laser PCB applications:ġ) Cutting tabs on sheets of ready-made PCBs. Cutting and Engraving Different Line Weights 28499. Here we'll take a look at some different PCB applications and how they relate to the laser. The vast majority of printed circuit boards are made by bonding a layer of copper over the entire substrate, then removing unwanted copper after applying a temporary mask (by etching), leaving only the desired copper traces.ĭepending on the desired outcome, Epilog Laser systems can be used in various capacities in the PCB realm. They support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper sheets and then laminated onto a non-conductive substrate, such as G10 or FR4. Printed circuit boards (PCB) are most often found in a variety of electronic devices. Here we'll take a look at the some PCB applications suited for a laser as well as those that are not. The blinking light means the print job is still being transferred and is not ready to start.One of the most common questions we get at Epilog is "can your lasers do printed circuit boards?" The answer is multifaceted and, depending on the application, there are some ways to use lasers with PCBs. Also, make sure that the green Data light on the laser's control board is done blinking before pressing "Go".Or, if printing from PDF, not selecting "Actual Size" when printing. Can also be caused by having entered different dimensions for the page size in the Epilog print menu than what your artboard / document size is.If you are using vector lines and tell it to run a vector job, check to make sure the lines set to the correct thickness, as it may be treating thick vector lines as raster data.The same is true if you have vector data but tell it to run raster jobs. If you have only raster data, but tell it to run only vector cutting, there will be nothing for it to do since there are no vector lines to cut. The graphics file can be transferred to the laser cutter. Most of the time, this is caused by selecting the wrong Job Type in the settings menu. For laser cutting we use corel draw as a drawing making tool.Problem: You send a job, but when you press "Go" it immediately says Done without anything being done.Ĭause: While a job is sent to the machine, it does not contain any actual data for it to work with.
