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.

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.

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:

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 ;)

I used to this when I had more time than money, the only way to get
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.
