 If you're using shrinktube, make sure you've picked tube small enough to shrink tightly against the wire. The bulges and sharp bits will hold the shrink very tightly. If you have sharp bits that are too sharp or too long you can cut them off with cutters. Slide your shrink tube onto the join, and rub the iron all over it to make it shrink. If you're using shrinktube, make sure you've picked tube small enough to shrink tightly against the wire.

 Ladies and gentlemen, meet my friend Via. Also known as a through-hole, a via connects one side of a PCB with the other, using a metal cylinder connected on both sides to an trace line or component. Occasionally you're going to want to install a new component on a PCB with a via, and this is how you do it. Note one new thing: Tinning your via is a bad, bad idea. Sucking solder out of these little holes is a massive pain in the ass, so you'll want to insert your components un-tinned. Ladies and gentlemen, meet my friend Via.

 Shown here is an Integrated Circuit (IC) but the same principles apply for any component, be it a resistor, diode or flux capacitor. Simply place the leg of the component through the hole. Typically the component will be snug against the PCB to minimize movement, but this may not always be the case. In the interest of saving space resistors are often shoved in vertically, for example. Shown here is an Integrated Circuit (IC) but the same principles apply for any component, be it a resistor, diode or flux capacitor.

 Place your soldering iron against both the component and the via, so that both are heated, and then apply the solder. The solder should flow easily onto both parts. Note that it doesn't really matter which side of the PCB you do this on, as they're obviously connected, and the solder will often flow through the via. This makes it quite difficult to remove and re-use, so be careful - get the right component in the right hole the first time! Place your soldering iron against both the component and the via, so that both are heated, and then apply the solder.

 Remove the heat, and you're done! This is possibly the easiest thing to solder. Be sure to trim those long legs on the underside of the PCB tho, typically 2-3mm is the max length for anything sticking through the PCB. Remove the heat, and you're done!
