Desoldering MCU/EEPROM

[MrWho]

Hi Guys,


What temperature you are using for de-soldering ( don't wanna fry the chip ) ?

What size nozzle you are using for De-soldering ? thin one or a bigger one ?

Should I add some flux before de-soldering ?


And what temperature you are using for soldering it back... with soldering paste ?

Thaaank YOU

Hey,

Thank you and don't worry about your english you are doing great... My is far from perfect too...

Do you pre heat the legs ... or you just set 500C and once is on 500 you will start de-soldering how many seconds ?

Thx I appreciate the help.

Cool tux again, I think I will tape around the eeprom some masking tape to protect other components.

How about if I put tiny radiator on eeprom when desoldering would that help with heat
thx
