Maybe time to use one of the free schematic capture programs, KiCad etc, and produce the gerbers needed.
Certainly be cheaper in the long run! ;)

I see none VSOP detail in there, thus the most elementary paper and ion method is more than good for pcb production at kitchen, balancing all things on the feet. Paper method allows a 0,1 mm ptch with about 20-50 micron inaccuracies. If more exact is needed, the Positivus-20 process allows about 50x more exact result, thus VSOP have more better look made on Positivus. Only one case is pardonable to order somewhere else is if the through-metallisation is demand. Simply that process is to so simple in kitchen to brew.
PS- first of methods demands an iron with electronically stabilized temperature 180+/- 10C. Normal iron walks between 110 and 350 with cycle of about few minutes. Paper must be as older as better. Nowaday paper is contrindicated, but all from sixties or early seventies is better as best.

You seem to have 3 choices:

1) Search this term "convert png files to gerber". Lots of possibilities will come up.

2) Use toner transfer or photoresist to transfer to a PCB and etch your own or find someone to do it for you. I prefer using photoresist for finer detail.

3) Redraw the schematic using any electronic CAD package. Get a proper (vector) PCB file and create the Gerber's from that.

I would probably opt for Option 2, as I suspect the conversion (Option 1) will have some difficulties, but it could be worth a try. If I wanted something I could sell, I would go to Option 3.

Thanks for all your reply's

I am trying to recreating the part of the design that I need, in PCB Artist.
I need a "place holder" for the LM1812 it is a N18A package

I am having difficulty finding a common IC that's still available in the package N18A

Creating a component from scratch is a bit more tricky

Can anyone help?

thanks

DH

It seems you will be linked to that manufacturer. Why not use something that will allow a choice?

Whatever you use, creating a component footprint is one of the basic things you need to know how to do. What is the specific footprint? Is it a standard that may be used for other devices?

EDIT:
If this is the package you need, it looks like a common DIP 18 package:

I didn't check every dimension, but 0.100 spacing and 0.300 wide is pretty common.

You mention getting the PCB's made, so at some point you will need the like's of Gerber files etc, wouldn't the effort be better spent learning a program that will do this. as suggested earlier? ;)
And also where you can create schematic symbols as well as device footprints, if needed.
