[Boatanchors] Multicore solder specifications?

[D C *Mac* Macdonald]

The Sn63 indicates a composition of 63% tin.

Normally this goes along with a Pb (lead) composition

of 37%.  63-37 Tin/Lead solder has the lowest melting

point possible of these two metals.  It is known as

"eutectic" solder and is highly desirable when you want

to use the least possible amount of heat when soldering.

 

The 63/37 solder is also weaker, if I remember correctly.
