Re: [Paparazzi-devel] component soldering in a tiny 2.11

[Prashanth Thankachan]

If you are not sure of doing this dont do it, as the powersupply has
quite big legs and needs a lot of heat to remove it and some skill to
remove all the legs at once, also there are very fine tracks close to
it and may get damaged... I know about this because I ruined one board
in the process of removing and replacing a powersupply...
However what can be done is you can cut/slice the brunt power supply
with a dremel and remove all the pcb and leave the legs independently
on the tiny board.
Following this heat each of the legs sufficiently to melt the solder
and remove them one by one. This method worked for me
