Joe,
I mis-remembered, saying Permatex's parent co. It is the Loctite parent
co. that now owns Multicore Solders. Henkle.
However , google on Multicore Solders brings up the distributor list from
the link I will embed here.

Apparently some government agencies and their contractors like to see excess
rosin flux removed and train their people to do so. I'm not sure why they do
that, but in the environment in which Elecraft rigs are capable of being
used this is completely unnecessary.

Thanks for the brief explanation of why the NASA solder specifications
are what they are, and the explanation of eutectic.
If anyone wants to know more about it,
http://en.wikipedia.org/wiki/Eutectic does a fair job, and includes a
phase diagram and is a good reference.

I checked the referenced link, and it contains the following statement: The
eutectic point is the point at which the liquid phase borders directly on
the solid ? + ? phase, representing the minimum melting temperature of any
possible alloy of ? and ?.
As I read that the liquid phase BORDERS on
The Kester solder Mouser part nos. are different in present Mouser catalog.
However, by inspection of the numbers which are similar I can tell you that
nos. containing 6040 are 60/ 40 solder.
Nos. suffixed with 88xx seem to all be NO Clean type, which you do NOT
want to use!
Most likely you have
Stuart,
please help me get educated; why would one not want to get the No
Clean type? It sounds as though it would not be corrosive, since you
don't have to clean it...
And if one wanted to go leadless these days what would be the best choice?
And differences between rosin and resin core
Perhaps I can offer a partial answer, Dave.
The best no clean solder (meaning it does not need to be cleaned for a
good, secure and stable joint for many, many years) is the same rosin flux
solder we've used for many years.
Rosin is NOT corrosive except when heated. At normal temperatures
