"The first 3.5ís did not flush worth a crap."

LOL!

two words: Siphon Jet...

-----------------

Eutectic solder may at the end of the day produce better solder joints because it has less of the mushy phase. "Cold" solder joints can be caused by the solder being disturbed during the mushy phase.

I had to buy some more Cardas Quad today and while Google searching found some interesting marketing spin on a Cardas Tri product page. The retailer claims the phone company had to reheat joints made with 60/40 solder every year, for reliability, until eutectic 63/37 solder was discovered.

" When the phone company used this type of solder on their main frames, every joint had to be reheated once a year to insure reliability."

It would be interesting to know if there is any historical truth to that...

We never reheated anything back in U.S.S.R. Solder was used POS-61, it contained Antimony, 0.5%; Tin, 61%; and Lead, 39.5%
For electronics organic pine rosin was used. I still remember that smell...

Edit: there was so called Solder type A, but it was used for phone cables only. It was exactly 63/37.

60/40 is a general purpose solder with a pasty range for a little workability.
For soldering electronic components use a eutectic designed for soldering electronic components.
The cheapest and easiest available eutectic is 63/37.
There are many others but all are more expensive and less likely to be widely available.

Here are a few other snippets from that marketing pitch:

"Today, all printed circuit boards use 63/37 eutectic solder.".......not if they are ROHS compliant.

"Cardas reports never having, or hearing of, a single failure in one of these joints.".....well George apparently hasn't seen any of my solder work

I am using leaded WBT 4% silver - excellent stuff
WBT 4% SILVER SOLDER (Lead based)

By the way old marry days in the USSR I was taught that silver is must for a good solder :-)
