TIP #
tip-089-when-desoldering-don-t-be-afraid
Why? The solder transfers heat to all the pins at once and you can easily remove the component. Do not worry to short all the pins with a lot of solder. It can be easily removed.

TIP #
tip-060-use-the-same-number-of-pins-and
Why? You want to clearly see from schematic where each pin is connected. It's very important when checking schematic and connections.
