Mini Solder spool - 60/40 lead rosin-core solder 0.031 diameter [100g]

If you're into making kits, this 100g (about 1/4 lb) solder spool is a perfect pick. It's just the right amount - not too much like those 1 - lb spools and not too little like the 'pocket clip' vials. With a 0.031 - inch diameter and 60/40 'no clean' rosin core, it's great for all through - hole soldering and some larger SMT soldering, especially when used with wick. Note that this solder isn't lead - free, but it's okay for European/UK customers for personal use only, not for production.

Using this solder spool is easy. First, make sure your soldering iron is heated to the right temperature. Then, touch the tip of the iron to the area you want to solder, and when it's hot enough, apply the solder. It'll melt and flow easily to create a strong connection. When soldering larger SMT components, using a wick can help make the process smoother. Remember, this solder is not lead - free, so it's only for personal use if you're in Europe or the UK. Don't use it for production work. To maintain the quality of the solder, store it in a cool, dry place away from moisture and direct sunlight. This will prevent it from oxidizing and keep it ready for your next soldering project.
