In MAKE 01 we have a great soldering primer, here’s another to check out from the Edinburgh Engineering Virtual Library. “This written guide will help beginners and novices to obtain effective results when soldering electronic components. If you have little or no experience of using a soldering iron, then EPE recommends that you practice your soldering technique on some fresh surplus components and clean stripboard (protoboard), before experimenting with a proper constructional project. This will help you to avoid the risk of disappointment when you start to assemble your first prototypes. If you’ve never soldered before, then read on!” Link.
