A better solution to try using a heat gun in tight places. Try using a product called CHIPQUIK (SMD1). All you need is your soldering iron. The product lowers the melting point of the existing solder. The chip then just lifts off.?

Simple components are easy. Clear the pads of solder and tin one pad only with a small dab of fresh solder. Hold the part in place with tweezers and heat the tinned pad until the solder melts and wets the part. Then solder the other end of the part. You have to be fairly quick about it or the part will heat up enough that the other soldered end will melt and the part will move around.
Or of you have two irons you can tin both pads, place the part, and heat both end at once. The part will magically center itself on the pads when both sides are molten.
Again, practice on some scrap boards.
My friend K0NEB, who writes the kit building column for CQ magazine, has talked of using a hot plate to heat the whole board up but I have never used this method. Probably not a bad idea to at least pre-heat the board this way for complex parts like the attenuator chip.
