This is a summary of some information on types of solder and their usefulness.
Summary: use the 63/37 Sn/Pb solder from Kester. It is eutectic and has a low melting point so that your opamps won't get damaged.
Eutectic:
We want our solders to be "eutectic" so that it goes from the liquid phase directly to solid with no intermediate slurry. This makes a reliable (and nice looking!) solder joint.
Lead:
The tin-lead solder is a good combo.
