As I've been getting further into electronics, I've been starting to hand solder surface-mount PCBs. While that hasn't been too bad at the 0805/0603 level, the smaller-pitch ICs and sockets are close to the edge of what I can reasonably manage (and, of course, are the expensive components when I stuff it up). I've started looking at the option of converting a cheap bench top oven into a reflow oven for these sorts of things, which seems to be a pretty popular project. While some people just use the oven as-is, I'd ideally like to use lead-free solder paste, it looks like I'll have to do a little bit of hacking. I'm fine with insulating the oven internally (which shouldn't be too hard), but most projects appear to embrace the US enthusiasm for hacking at mains wiring without a licence. I'm not keen to do that myself, so thought I might ask here to see if anyone has had any experience with this kind of DIY project. A couple of more specific questions: Has anyone had any experience with some of the plug-in controllers such as Reflowster or Beta Reflow controller V3? Any other suggestions welcome as well, obviously From my reading here, I've often seen people say that you can have your own work signed off by an electrician as being safe. Is there any chance that I could wire up the relays for one of the more elaborate controllers (e.g. ControlLeo2 or X-toaster and have an electrician look over it, or would I need to employ someone more specialised? Thanks in advance for any advice!
