Re: busy: solder temp
- Bill is correct. The higher the tin ration, the higher the melting
point and also the higher the strength of "a well made joint". One
thing to be carefull of is "cold solder joints". This usually occurs
when the rail (or wire) moves as the solder is cooling. The joint will
have about half strength if that happens. It usually has a frosted look
rather than the solder being shiny. With rails, since we are trying to
keep all the solder under the rail, a little to much heat is better than
not enough, but not too much.
It has been years since I went through the solder certification program
and there are a lot of new things being used nowadays. New fluxes and
solders (even lead free ones). One of the fluxes we use at work is a
water based one, rather than having to use alchahol to clean up with.
DEFINATLY stay away from the acid based fluxes. They are fine for
plumbing pipes and such, but not hobby stuff or anything with circuit
