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 .
My soldering training said that use of solder braid gets more heat applied
to the PCB for a longer time,making pad lifts occur more.
Same for SoldaPults.
They specified the use of a temp controlled vacuum desoldering iron.
