Means of going from a pdf file board image to a file to engrave from?
07 June 2018
I restore old test gear and sometimes have to make new boards as some old PCB's suffer from poor track adhesion when repairs are attempted. I have fixed up a huge linear bench DC power supply but really I would like to make new boards. I use a thermal wax printer to put the layout taken from a Photoshop modded photograph of an original single sided board onto clear sheet and then use photo resist to make a board. but I'd like to get an engraver and try that method. Hence I need a means of going from a black and white pdf image to a file suitable to run on the engraver. Any ideas if this is possible and if so how to achieve this please? There's a link to the images I would want to convert here, the images are actual size: Thanks for any ideas! A means to convert to a format a pcb fab house could work with is another possibility, I am happy to drill the holes manually on my milling machine. -- Best regards, Chris mailto:chris@... |
You can convert the scanned image to a vector image, the vector can be used

to run the engraver. Eg: That was done using CorelDraw with the default setting so can be improved on. CorelDraw doesn't do the best job, but I already had it open. I usually use VectorMagic for this stuff. InkScape has an image to vector converter as well, that's free but I've not used the converter. Tony -----Original Message-----file to engrave from? |
The Pulsonix PCB software I use can convert PDF files to Gerbers. I could probably convert that file for you.

Sorry, it looks like I was wrong about Pulsonix being able to convert from PDF to Gerber. It does work the other way round, but that isn't much use.

Here is a PDF to Gerber converter: Leon On Thursday, 7 June 2018, 17:58, Leon via Groups.Io <leon355@...> wrote: Sorry, it looks like I was wrong about Pulsonix being able to convert from PDF to Gerber.

Hello Tony, and everyone else who replied.

I have been away working but now I am back I will experiment, the info has been extremely useful, thanks a lot!! If I do not succeed would anyone be interested in doing 3 decent vector images or something i can send to a PCB fab house? I would happily pay a reasonable sum by Paypal gift! I can provide evidence that I am not a bandit ;) Thursday, June 7, 2018 You can convert the scanned image to a vector image, the vector can be used Eg: That was done using CorelDraw with the default setting so can be improved InkScape has an image to vector converter as well, that's free but I've not Tony --

really clean gerber files was to trace every line by hand with new tracks and pads. A layout software that can import pictures was vital for that so you can draw over it. These days, I have more money than time and am not interested. I would say it should take someone proficient about an hour for the first board and less for each one after that, that is for boards that are "good enough" rather than "can't tell the difference". Your PDF is very clean, surprisingly so (old layouts are often crappy), so if you can find a technical way to convert this you might be in luck. But the problem is gerber files are essentially "go from point a to point b in a straight line" style instructions, the curved lines are a real problem and must be interpolated from segments. The same issue applies to a mill by the way, these boards really suit themselves much better to a photo process or toner transfer. ST On Fri, Jun 15, 2018 at 5:44 PM, Chris Wilson <chris@...> wrote:
