I don't use reflow either mind, it's all manual stuff with a regular iron - ok for small runs, but it takes an hour or two to do one polarshield board. SMT is actually nothing to be afraid of, once you've done it once the mystery disappears, seriously, and you wonder what all the fuss was about. If you're just a bit handy anyway. Mess up a couple of components, just knock them off and try again. As long as you baby the pcb a little so that you don't get it too hot and risk lifting the traces, it's actually easier than through-hole. As a guide, I am a very amateur soldererer, and I've only ever ruined one board, and that wasn't even my first one. But aye, less forgiving. I think having the right equipment makes a difference.
I stick the pcb down with blu-tack,
- use close up magnifiers (http://uk.farnell.com/jsp/displayProduct.jsp?sku=1834302&CMP=e-2072-00001000&gross_price=true),
- a flux pen to flood the area that you're soldering (http://www.somersetsolders.com/product.php/223/75/no_clean_flux_rework_pens) (though I'm sure you can often get away without that, depending on what technique you use),
- 22swg solder (http://www.rapidonline.com/Tools-Equipment/Rapid-Premium-Lead-Free-Solder-22swg-100g-Reel-85-6612/?sid=bd445df9-52b7-4286-a390-85f8d6f3b9fb)
- Antex TCS-50 iron with a 1.0mm chisel tip
- Decent tweezers (http://www.somersetsolders.com/product.php/815/339/precision_stainless_steel_tweezers___7sa)
Whether you want to bother with all that stuff really depends on how often you think you'll use it. I know I won't go back to through-hole unless I am deliberately making something that is more accessible to other builders. Also since folks like ITead or Seeed or elec-freaks offer pcbs so cheaply, it's hard not to. Drilling hundreds of holes? No thank you.
I'm in NO hurry to assemble more than I have to, but I could do the smt stuff. The biggest problem with it is that I can't test an unfinished board without some kind of clever test jig, and that's more £££.
Price for PCB on it's own would be about £6, plus components about £12, with soldering done about £26. Postage for a pcb would only be a few quid though, even worldwide. The lcd is about £12 if you got it through me.
What I want to avoid is making something that lots of casual people want, but can't afford to get on a whim, so I'd love to get something on the go that was really cheap. Not there yet.
