The RHTOV20 was a fair bit taller and much deeper, so it had a lot more empty thermal mass to deal with. I compared both in the store and I figured the 9L size of the Sunbeam will really help with getting a nice steep profile, especially with a boost element which I'll be adding in as well (I have some thicker gauge power cable for the mains connector to cope with the extra wattage just in case). I was tossing up between this and the Russell Hobbs RHTOV20 with convection. I got the oven today too (Sunbeam BT2600): All the reviews I've seen have said, cheap means melting adhesive and smoke. You could end up going through 3-5 rolls of cheaper tape and still not find something suitable. If I was building more of these or decided to flog the other boards off then that's a more economical solution (it would work out about half the cost), however you do get official support if you buy from whizoo.Ĭlick to expand.I ended up getting the official stuff off Amazon - įor the price difference, time and cleanup possibly required, I wouldn't bother with the cheap stuff. However, with OSHPark it would be $42.60USD for three boards and the rest of the components would make it almost the same price. I also considered building a software compatible controller myself from here. I will check it out and see if I can install an convection fan later. All the convection ovens are all much larger and quite pricey. I'm still tossing up over the Sunbeam BT2600, the sizing is right. If their shipping was cheaper on the build kit, it would totally be worth it provided their SSRs are to spec (I noticed the ones in your post aXLe are branded differently, so these might be fine). The kit seems to be pretty good in terms of pricing, I've only saved a little by using existing/ordering the parts. I have sourced all the other parts as well from my misc bins and online (the legit thermal tape being the most expensive). These will help me reduce space and I was also concerned about the quality of the SSRs that the build kit comes with. At the very least some opinions of the oven/controller combo performance.Įdit: I've ordered the ControlLeo board/enclosure only as I found a couple of old and used Crydom d2440d Dual SSRs sitting in a junk bin at work. To date I've been hand soldering (including hot air reflow) or using a hot plate which works OK for leaded solder but at some point I'm going to have to go lead free!Ĭlick to expand.I'm looking at doing this exact build, I would definitely be keen for a thread (and would be happy to add to it once I run my build). I'm yet to find a cheap assembly place for small runs (20 boards or so) thus the purchase of this kit. I've been panelising boards lately on a small panel suitable for the Stencil8 stencil system - using that and an oven should speed up small volume runs even though I will still be manually placing components. It is supposed to be able to achieve a decent reflow profile with fairly even heat distribution - partially thanks to an additional booster element that is supplied with the kit. The kit it pretty comprehensive, though there are additional items such as external insulation that I will have to source. Most of the documented builds are with US model ovens - I need to find a decent local one - recommendation is for around 1600W output. ![]() I just received a ControLeo2 kit in the post today ( ) and am now on the hunt for a suitable toaster oven to mod ControlLeo2 or X-toaster and have an electrician look over it, or would I need to employ someone more specialised? Is there any chance that I could wire up the relays for one of the more elaborate controllers (e.g. 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.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.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. 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. 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'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 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). As I've been getting further into electronics, I've been starting to hand solder surface-mount PCBs.
