MG Chemicals - 4884-227G 63/37 Rosin Core Leaded Solder, 0.025 Diameter, 1/2 lbs Spool

This is high-quality stuff, believe me it is not easy to find solder this good anywhere else. Melts properly and flows smoothly. This small diameter solder works great for very fine jobs.

This solder flows very well and is very controllable due to the small size. It doesnt leave a large amount of flux behind but theres still enough that I would suggest getting some flux cleaner if you want your board to look perfect.

Novice solderer. Working great for me so far. Seems to be the right size for doing electronics.

This solder works great, flows easy but sets quick. I would recommend this to a friend, 63/37 is the only way to go for ease of assembly when building circuits.

MG never disappoints. Always great quality and consistency.
