Does anyone on here make PCBs?

I need a small batch done on the cheap, and I'm struggling to get consistent results with that press'n'peel stuff.

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.

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.

Haven't done it for ages now, it's so much nicer to do double-sided boards with solder masks and use an online service if you don't mind waiting 7-10 days to get a decent price.

I don't deal with electronics stuff so might be barking up the wrong tree, but we have a circuit board milling machine at work if that's any good to you?

Etching is ok for clumsy big circuits. Small stuff they can done very well but getting it right verges on impossible as the timing, strength and temperature have to be well controlled. Ferric chloride is terrible at staining things, and those things in turn can quite happily stain other things, and you won't be getting it out. Milling avoids these problems but replaces it in the case of small circuits with depth control of fine cutters which snap easily.

Confused I'm so lost in The Geek Zone, it's like you all speak a different language Laughing

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.

I'm honestly lost with this stuff

I wrote that post after getting back from the Science museum in London Laughing

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
