Surface mount component soldering

[Serum]

A friend of mine once had an issue with a microprocessor in a beamer; i remember he removed all the shrink wrapped items and put it in an oven.

you can get very tiny blow-holes for a paint removing. If you know a certain part is damaged, just put the soldering iron on that particular part and let the heat flow through..

You can solder an SMD part with a very small tip on the soldering iron. Remove the tin from the board before you start soldering though, otherwise there might appear a weird tension in the part/weld to remove tin you can use litze.
