Great for SMT soldering!
I was stubbornly trying to use 0.8mm solder for everything. Although it works well for larger through hole parts, it very easily creates excess solder blobs when trying to solder fine pitch surface mount parts.After limited success with 0.8mm, I finally decided to try this thinner solder. It is a game-changer! So much easier to control how much solder is being applied. I can highly recommend this alongside 0.8mm solder and some decent flux for the vast majority of soldering tasks!

0.3mm (0.0118 inch) dia, about smallest available. 63/37 flows more easily than lead-free solder
This is a very good choice for fine-pitch soldering. For best results, use a fine-tip soldering iron.

For making electrical connections
Melts @ low temperatures , contains proper amount of flux

Decent quality - Not the best for fine electronics
This is decent quality solder. It’s not amazing but not terrible. I recommend using a 0.3 or 0.6mm wire for small electronics work such as HDMI replacements etc, this stuff is too thick

Easy to use
This soldering wire is way easier to use than your average mm they give out in a kit. Great packaging and lots of choices.
