Re: [Xylo-SDR] Toaster oven

Before I'd waste the time and money on modifying a toaster oven and
buying the solder paste (which is quite expensive) I would invest in a
stereo boom arm microscope with about 10x magnification.  That,
combined with a nice small soldering iron tip, will allow you to
easily solder the 0.5 mm pitch parts.  You can get a brand new boom
arm microscope with light and 8" working distance for about $250.

See my blog for more info: http://pcovington.blogspot.com/

You still need to be able to inspect your solder joints if you use the
toaster method anyhow... the microscope does double duty as an
inspection scope here...

Now, for BGA's, the microscope won't help you.  Take a look at
SparkFun.com for info on his shop...  He uses a hot plate and it is
superior to the toaster oven method in many ways.  He explains why... 
Good reading...
