All: I have two partial pounds of Multicore left. With all the RoHS stuff
in play, it appears that standard solder is getting harder to purchase.
Where do you guys purchase your solder?

Reminder that the Collins Net will be on this evening at 8 PM EST on 3805
Khz.
Is there any interest in starting an AM net on 3805 Khz starting at 7 PM EST
on Monday's? I wouldn't mind getting on immediately before the Collins Net
to serve as net control.
Thanks

I have always used 60/40 Rosin Core Solder for soldering.
Is there anything wrong with soldering older boards in the older rigs using
Kester Rosin Core 63/37 Alloy.
Looks pretty close to me, but I am not sure since I have never done it.
Sure is a lot cheaper.
Tnx

63/37 is the solder to use - Kester is good but Ersin "Multicore" is the
best. 63/37 is the mixture that turns from molten to solid the quickest
- 60/40 has a larger "plastic" temperature range.

IIRC, and I'm pretty sure I do, 63/37 is the eutectic alloy: the one
that goes directly from molten to frozen with zero plastic state in
between.
IMHO, the only time you want to use something else is when you're
soldering stuff that requires silver-bearing solder, such as Tek scope
terminal boards.

Bill,
As long as the subject of application is a boatanchor, you have the
right stuff.
Do not throw away the 60/40. Thats good enough for lots of things also.
Some times fast is not always best.
63/37 works well on printed circuit boards also.
If it has a printed circuit card, is it a boat anchor?
Are those two item mutually exclusive?

Of course not! The SRR-13 (and its relatives, the FRR-23, SRR-11, etc) has
the tubes soldered down to PC boards. It weighs about 70 pounds and thus
easily qualifies for boatanchor.

Hello All-
I worked in Albuquerque, New Mexico for Electronic
Parts Company for 16 years (1977-1993). We stocked
60/40 rosin core solder by the 1/2lb and 1lb. spools.
We also stocked 63/37 Ersin Multicore solder in one
pound spools. For general purpose applications
including printed circuit board applications, I do not
recall any complaints about using the 63/37 as a
substitute.
I agree with using 63/37 as a substitute for 60/40 if
the former is unavailable. It should work just fine.

Unless, of course, you are working on an audio amp with tubes like
304TLs. Then you MUST, ABSOLUTELY MUST, use WECo 123 solder, made only
in the Oshkosh factory by Swedish elves, or our sound clarity may be
fatally impaired.
Actually, the 63/37 is eutectic and makes very nice joints. The Kester
44 has a good flux that does not corrode even after decades. It's the
stuff NASA and the USAF have used for at least 25 years.

63/37 eutectic has a 1 degree plastic range. Been using it for a couple
decades now
commercially and hobby wise.

63/37 eutectic has a 1 degree plastic range. Been using it for a
couple
decades now commercially and hobby wise.
Just to pick up a couple of loose ends:
The 63/3 means 63% tin, 37% lead and is the metal alloy of the solder.
That's the same manufacturer to manufacturer.
The Kester 44 is the FLUX type. I think it's RMA... Rosin, Mildly
Activated (or Active). Likely Ersin uses a somewhat different flux.
Finally, the o.o15" OD is a bit thin for BA work. That just means you
will have to feed more length of bthe stuff.
I've been using the Kester 44 for at least 25 years and it works very
nicely. One caution: it may start to get harder to get soon as the EUC
and others have banned lead.

I too used Multicore for years and years. I must say: "BEWARE!" Multicore
has some newer solder fluxes that are absolutely awful! Maybe the kind that
washes off easy or whatever. Anyway, make sure you get the OLD type flux
combination! I have a pound of Multicore here that is unusable.

Sandy,
What's wrong with the newer stuff? What does it do? I've always preferred
Multicore to anything from Kester (despite the fact it makes good joints
that
look like cold solder joints).
