In the cheap electronics i dont think you can do much . I work on the
cheaper stuff , basically brand new store returned items such as small
stereos & such .
Sometimes foils lift just by handling the board and pushing or tapping
lightly on parts .
I would say keep your soldering tips in good clean condition and dont
heat anything very long . If you can get hold of the part first and pull
on it while quickly heating the pads the part will pop out then very
quicky use de-solder braid to clear the hole .
Use lower heat irons . High heat can very quickly fry whatever holds the
pads on .

An iron with a built in 'solder sucker' helps a lot.

Radio shack has an el-cheapo with a red rubber bulb that works well, or one
can buy an expensive vacuum equipped desoldering station (with temperature
controlled iron).
