Can I use the kit in a small oven of 600w and with 9 liters of capacity?
I dont see why not, but at 600w, it will have a long ramp up time unless it is well insulated.

I have T-962A and after many burned boards and partially soldered boards I can now use it to produce perfect repeatable results.  I've made several hundred pre-production boards in that oven.

The biggest problem, as with Dave's new oven, is the base is a solid piece of metal and it conducts all the heat away from the boards (especially 0.8mm PCBs).  To get around this I have some old FR4 boards I use to lift the corners 1.6mm (or sometime 3.2mm if it has a massive copper plane or big Module.  So long as there are no parts where you lift it it will be fine.

Also one of the heaters is better than the other so I have to put the boards towards the back to get it right... which can be helpful if you have lots of copper in one place and less at the other end of the board.  You can more evenly heat it this way.  They're not that shit when you know them and what beats the toaster oven is the cooling fan which cools them after reflow ready for the next batch.

Also you want to run it through once first time before you use it to warm it up!

I'd be concerned using any reflow oven like that in an office.  I take my boards from the office and reflow them in my garage as the fumes put me to sleep!

Hey guys.

didn't read all the posts on this topic, so sorry if this question already was answered.

what do you think, is this device capable of reflow bga components or would you have to heat up the µC so much to reflow the solder underneath so it would destroy the controller?

background to this particular question is: a while ago i was thinking of buying a quadcopter kit, but the controller board would require bga soldering, the fully assembled board would cost 150€ ( yep, i'm from germany ) more then the non assembled one.

now i'm wondering if this reflow oven could solve such assembly problems for those kits.

I bought a BETA layout controller some time ago, although I use a different (convector) oven.  I wrote a Graphical User Interface (GUI) which interfaces to the BETA layout controller, making it much easier to configure the unit to match a specific solder profile and also to monitor and plot temperature in real time.  It's a free download, for anyone that would like to use it:

Looks like they have updated the reflow controller to V3 Pro. Someone already bought it?

Here is a project much like this that showed up on Hack-a-day.

This looks like it would be much more flexible the one you tested in this video.

Just thought I would toss this in there...
