I use AD accels in the exact same package at work, the hardest part of soldering them is heating the package itself. The solder pads run up the side, so soldering it with a soldering iron is very doable. It just takes a beefy temp controlled iron to heat the case. I use a weller SP80 iron with up to 80W and its still slow at first. I prefer to tin the pads on the board with plain solder (no need for paste) sit the chip on top of the board, add a bunch of flux and heat the whole thing on a hot plate to pre-heat it, and use a hot air pencil to flow the solder. I would imagine you could do something similar without hot air, and just the hot plate, just watch the temp carefully. If hot air isnt available, a hot plate and soldering iron will work. Tin one pad, and use that to hold the chip in place as you solder the rest of the leads. Without a hot plate, you'll just have to put a blob of solder on the iron and wait for the chip to heat up before it solders nicely.
