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.


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.


The tin-lead solder is a good combo.
