Benchtop IR Reflow Ovens

I'm wondering if anyone has any opinions or experience with small benchtop IR reflow ovens like these:

The one on ebay appears to be a clone of the maddel model.

I've been trying to decide whether its better to get one of these small IR ovens or a good hot air rework station. Anyone have experience with both? Comments or opinions?

Thanks

Isn't that the one that nathan had such fun with? Look in the tutorials section.

It's the mini clone... I haven't used one, but the big brother really didn't work for us. I've also heard from a SFE customer that his mini was DOA from Hong Kong.

heh I had my money saved up for one of those mini infrared reflow ovens, but since it sounds like they don't work very well, I bought a convection toaster oven, hot air rework station, and a nice oscilloscope instead.

Now I have two other questions:

1) Can toaster ovens be used for soldering both sides of a board? It would seem they would only work for single sided, or am I wrong?

2) Can a hot air station be used for soldering those tiny chip capacitors and resistors? Doesn't the air blow them around?

Thanks,
Doug

I turn the air down when soldering 1206s, 805s, sot23s and such. You might want to be a little careful with how fast you heat with hot air. Could cause thermal shock or over temp. I've broken ceramic chip caps.

However, I find that the little stuff goes pretty fast with an iron so usually don't bother with paste. Just tin a pad, hold the part in place with forceps and touch the iron to it. a little flux on the part helps a bit. Then finish the rest of pads with solder and iron.
