[Elecraft] defluxing PCB's

Tue Apr 22 23:31:01 2003

I really don't know.  I've soldered one heck of a lot of stuff over the 
years, always using simple ol' 60/40 activated rosin solder -- nothing 
special.  And I've never (I repeat, never) had a joint that I couldn't 
inspect with ease.  I suspect some are dwelling as much too long on their 
solder joints as they are on this topic.

best wishes,
