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

This is the One Solder For Everything. The flux is effective, but at only 2.2% doesnt leave a huge mess. The diameter is stiff enough to be easily used, but thin enough to provide good control for everything but the tiniest SMDs. The alloys is eutectic lead/tin, the best all around choice available if you can use leaded solder (which you really want to do). I have several different solders available, almost all leaded. This is one of the best all around-- up there with Kester and Alpha.

This 63/37 (tin/lead) solder has worked out very well for work with thru-hole components on a PCB. I have built a QCX transceiver and have no complaints from the solder department. I may be tempted to use this thin-gauge solder on a SMD project that is in my future. It may be a tad too fat for that; maybe. This solder matches my experience with Kester solder. Both good.

Wonderful!

I needed a small-diameter solder to attach some SMD parts and found this 25-mil roll on Amazon. Turns out that I could really use something even smaller, but this works well and has a good flux core. Keep in mind that this solder does contain lead, so its not RoHS-compatible. But solder with lead sure flows nicely.

Eutectic solder as advertised, works without that dreaded plastic-y phase you get with 60/40 blend. The rosin core is plentiful and aids in keeping tips clean and lean (and smells lovely! But thats neither here nor there, perhaps I shouldnt be enjoying the fumes as much as I do haha). Definitely recommend this for anyone doing electronics work or anyone looking for a eutectic solder. Good value for a half pound roll, which if I ever finish I will buy once again.
