Subject: Solder: what kind of solder to use and why? 

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.
