For SMD projects, rather than repairs, you can use a domestic oven to
solder the boards. Ideally, get a small table top model (the type of thing
student or caravaners use) but I did a test run in a full sized kitchen
one. The key thing is to be able to get to 230C or so at least.
You need to plot a graph of the way the oven temp rises using a
thermocouple (I borrowed one but they are cheap enough to buy). Basically
you put the board it with all the components held in place by solder
paste.
Set the temp to about 200C and watch as it rises. When it gets to 100,
turn
oven off for 3 min, this is known as drying time and is to drive the
solvent from the solder paste, them set temp to 250 or as high as you can
if lower. Now watch carefully, as soon as the solder paste melts and flows
to make the joints, turn off the oven and open the door.
I've tried this a couple of times and the results are surprisingly good.
No
dry joints, no moved components.
The graph will help you predict when things are about to 'happen' and the
thermocouple is essential if your oven temp. gauge isn't accurate.

Following on from your repeated childish sneer about vapourware and your
inability to establish your own bona fides in respect of completed projects
I suggest that what you type above really does take the biscuit in
terms of confabulatory Walter Mittycism?
