Iron-on / toner transfer is great for making prototypes, but as you have
found, the results are not quite up to production standards.
Photographic method is better. You can make the artwork using
acetate film (Staedtler or similar) and a laser printer. For best
results, I print two sheets and stack them for better opacity
of the circuit tracks. I use a standard 500W halogen outdoor
light from B&Q as the UV source for exposing the photo-sensitive
PCB and a weak water/caustic soda solution for developing the boards.
This works well for simple, single-sided boards.

OK. I'd been hoping to avoid the light method, purely because of space constraints and relative tightness of cash. I'll have a look into doing it, but I'm a bit sceptical of buying a bunch of developer and UV lights just for a single use.
I might just practice a bit more with the press'n'peel stuff first, though. ____________________ '10 SV650SF, '83 GS650GT (it lives!), Questionable DIY dash project, 3D Printer project, Lasercutter project |

I don't know if this helps.
2 layer boards are $5 per square inch (with 3 copies of your board included in that price) and ship in under 12 calendar days from ordering.
4 layer boards are $10 per square inch (also including 3 copies of your board), go to the fab once a week, and have a 2 week turn time from the fab.

I'm so lost in The Geek Zone, it's like you all speak a different language
I have no idea what Mr Ridah actually said, but if that makes the milling machine any use I can probably sign you in one weekend and you can work your genius magic on it, or I can speak to our department resident circuit genius and he can tell me what files it runs on. Or something.

How many, what size and complexity?
I made this single sided board for an Atmel 328 uC ( Arduino )
using .9mm drill and vee bit from a vector/dxf file.
I've made smaller ones for my Home, brew flasher units and stuff
and more of an enthusiastic amateur than expert
