If you're doing only a couple of boards then I find it's better to get a local shop to make the boards for you. There are many ways to etch the boards and for most, UV etching seems to work the best - therefore, you will spend a lot of $$ buying proper equipment. Alternatively if you are on a tight budget you can still draw / etch by hand - but the chemical solutions aren't cheap to buy.

Do the homework and price out what a PCB shop can make them for you. For me, it was a no brainer getting boards done locally and tin plated. You can check out my PCB on my website

Super_BQ,
What kind of $$ we talking about here? The places I've looked at it would have been well over $100 (CDN) for one board.
I noticed your bio said NZ and Canada; have you got a cheap source here (Canada)?
p.s. Nice site. Nice projects!

Default Prices

PaulB,

I did 6 boards (4 main + 2 power supply) for a total cost of $140 NZ which is around $23/board - also includes tin plating. Max. board dimension was roughly 14cm x 14cm (didn't matter if the boards were much smaller as it would be the same cost). The local shop charged $40 for filmwork ($20 for each PCB layout) so in the future if I do decide to make my own UV etched boards, I can use these negative film slides.

Now let's talk about savings. Converting those prices to Canuck money ($1nz=0.67cdn). We get a price of around $15 cdn per board. Of course it may be far fetch to compare Canadian labour rates to NZ labour so I expect not many people in Canada can take advantages of these savings.

For a home based UV setup. Locally in NZ you can spend at least $150 for a proper UV box. Then you need to buy special UV lightbulbs. So easily $200 on hardware. I havn't looked around in Canada for prices because places like Radio Shack don't normally stock those items (i know places in Vancouver that do carry those items). Not a necessity but i'd buy a heater for the etching fluid which is another $80nz.

Then you have to look at etching the boards after UV baking the PCB. You can use the powder stuff (just add water) or the liquid ferrous sulphate stuff. The powder stuff is cheaper but doesn't work as good - $20/liter. The key to making clean PCB is to keep the etching solution hot.

Optionally, the boards can be tin plated or simply laquer laminated to protect the copper from oxidizing. $10 fix.

I'm surprised where you live to get boards done is so expensive. I was expecting no more than $50cdn each. I sure hope that includes resist plating or at least, tin plating.

Brendon

Your prices sound pretty reasonable. It's been a few years, I should check around again. There are sources for bulbs and things, but I want to design & solder stuff, not play with chemicals and etching vats.
I was hoping you'd say you found a great cheap Canadian source for boards...

no way :-
UV light setup, 35
chemicals - 20
board - 10
laquour - 5
a little time and care - free

you don't need a heater or any fancy UV box, just make ur own out box of all that MDF lieing around , get a couple of small UV striplamps and fittings, bobs ur unkle

PCB milling machines are getting cheaper, have a look at <a href="http://www.techsoftuk.co.uk/page49.htm">Roland MDX-15 MDX-20</a> 3D Scanning and Modelling/Milling in one.

Theres a downloadable demo PCB layout programme on PCB CAD/CAM page.

Regards
James

I gotta get me one of those!!!

The milling machines would be fantastic, although at 2050, you would need to be making a lot of PCB's. Maybe a small business could be built around one of those...

Default UK Pound vs Kiwi $

You're forgetting the UK pound is worth 3.33 times the NZ$. So adjusted for NZ currency:

UV light setup, $116.55
chemicals - $66.6
board - $33.3
laquour - $16.65

To the original poster, here's a Canadian link that will help you: (if you want to do as much by hand as possible and not worry about neatness of the etched PCB:
