- You might also consider "Solders and Soldering",by Howard Manko for
- sketchy properties. The International Tin Research Institute (ITRI,
- Uxbridge England) has a nice compilation of tin based solder
- properties which they will send you if you ask nicely. There's also
- the monograph "Solder Mechanics: A State of the Art Assessment",
- edited by D. Frear, W.B. Jones and K.R.Kinsman which may include
- useful information on solder properties and more importatntly, how to
- interpret published properties, i.e., what behavior to expect at what
- templerature and stress state conditions.
