You probably mean Ersin Multicore solder. There is some on eBay, says
on the label that there are factories in USA UK Canada and Malaysia

If you're really looking for some of this in the 60 /40 Pb.Sn variety, snap
it up soon when you find some. All of the solder is going lead-free in the
EU, and it will be illegal to use it commercially after June 2006, so I
suspect that there will be lots going cheap over the next couple of months
whilst dealers try to offload their remaining stocks. Equally though, there
will be many of us lead-free haters, who will be trying to buy it all up, to
leave us with a lifetime's supply ...

I think it was also Ersin who did " Savbit " solder. It had a trace of
copper in it as well as the lead and tin, and helped to keep pure copper
bits, such as were fitted to the Adcola ' poker ' irons, the early Antex
CN15's and the Weller guns, from getting eaten away by the corrosive action
of the flux cores. I don't suppose it would be relevant now with most tips
being iron clad, but the Antex needle tip that I use for surface mount chip
rework, is still a pure copper unclad type.

Count me in, I despise lead-free solder, it just doesn't work worth a
crap compared to the standard stuff. Joints tend to be cloudy and blobby
and it's hard to make it flow well. Guess I better stock up.

Absolutely, James. I have written whole pieces in magazines about the
hateful stuff. Soldering on printed circuit boards was, until a couple of
years ago, a tried, tested, reliable and mature technology. Bad joints,
except in the ' traditional ' places, had become a rarity. Now, I see more
and more, often on huge surface mount ICs, where you would never have seen
them before. There are also issues with mixing leaded and lead free solders.
Most of the current wisdom states that a joint with mixed composition, is
potentially more unreliable, than either type on its own. I think that it is
absolute madness to make it law such that a board originally fabricated
using leaded technology, has to be repaired using unleaded, after June this
coming year.

I currently have an issue with a device that I use many hundreds of in the
course of doing a modification to a particular industrial board that I see
hundreds of a year. Over here in the UK, none of the suppliers who deal with
this component, can supply me in the numbers I require, unless I am prepared
to commit to them ordering in a year's supply for me. For a little guy like
me, who is at the mercy of the whims of the company that I do this work for,
this is not an option. So I found a company in the US who can supply me with
as many as I need, when I need them and, even allowing for exchange rates,
shipping and import tax, can still supply me them for 2/3 what I have to pay
here. It has worked great for the last year. Now, on enquiring, it seems
that in the US, the lead free version of this component, is not going to be
offered so, lead free rears its ugly head again, and shafts me on this very
good business.

I wouldn't mind so much if someone could demonstrate to me the need for the
change. Apparently, over 80% of the world's mined lead, goes to automotive
battery manufacture. This has been exempted because there is " no viable
alternative to this technology ". Instead, vigourous recycling mandates have
been put in place. Fair enough. However, only 2% of mined lead finds its way
into solder, and again, new recycling mandates for end of life electronic
equipment, have been put in place throughout ( supposedly ) the whole EU.
I'm pretty sure that millions of people are not being lead poisoned as a
result of there being leaded solder in the electronics that they interact
with, and if the stuff is going to be properly recycled at the end of the
equipment life, JUST WHAT IS THE ISSUE ???

I would say just how long is it going to be before 400 people get killed
through a 747 falling out of the sky as a result of bad joints, or how long
before people start dying in hospitals ( " Charge to 300 - CLEAR !! "
click... fizzz ... " Oh SH** - someone bang the side quick ! " ) but
interestingly, as a result of strong lobbying, the avionics and medical
instrument industries, seem to have succeeded in securing at least temporary
exemptions. Now ask yourselves, what exactly does this tell us about lead
free soldering ... ??

Perhaps we should start ' CALFS ' - C ampaign A gainst L ead F ree S older

I would be interested in hearing other peoples experiences and thoughts on
this subject, anywhere in the world, and particularly anyone directly
involved at production or bulk maintenance levels. Feel free to mail me
direct if you would prefer not to be ' public ' on the group.

BTW, there will always be Tin / Lead solder available. Yes, Lead free is
being used in new fabrication -- BUT conventional tin-lead materials
(components) are NOT compatible with the new lead-free device finishes.
As part of the global transition to lead-free, component manufacturers are
switching to lead-free finishes -- BUT this takes time and inventories are
very large for some components.

Pure Tin and Tin/Lead alloy solders are used in other industries that do not
have these restrictions .. such as the stained glass industry, auto body,
restoration work, etc.

Our factory is moving to be RoHS compliant by the EU deadline of April.
From my reading of the directive you can still use lead solder and non-
RoHS parts for maintaining equipment sold before 1 April 2006 but not for
equipment after that date, even if same model.

I'm looking at using AIM's CASTIN as our Pb free solder, looks to have
the best properties for use in current type of soldering equipment we
use. I'm recommending keeping separate facilities for Pb and Pb free work
/ rework to prevent cross contamination.

Wes.

One place where lead-free has made a welcome appearance is in plumbing.
I'm an occasional handy-man, so when I bought a house a few years back
which had really BAD piping in the basement, I resolved to replace all
the crappy, mismatched and kludged up mess with new copper.

I was surprised to find out that all the supplies available were
lead-free (I suppose I shouldn't have been, but the last time I had
sweated any copper pipes was in the 70's). The old acid based flux
seemed different as well.

I determined to undertake this task with some trepidation; but to my
gratification, all went very well. The new stuff works just fine, and I
didn't have to worry about miniscule amounts of lead leaching into my
drinking water.

Considering what supposedly happened to the Romans, I guess it's not all
bad....

Isn't copper more poisonous? If you drop a lump of copper in your
aquarium the fish die. A lump of lead has no effect. To kill a tree
you hammer copper nails into it.

The nice hard water forms insoluble lead salts coating the inside of
the pipe. I'm sure the copper salts are soluble, and end up in your
tea!

Interesting. As I said, I'm only a part-time handyman...and most
certainly not a chemist or biologist.

I'll let someone with more background answer this one.

FWIW, copper is mandated for supply lines (from the meter to the house)
in my municipality.

In the UK it's plastic. Which replaced lead. ;-) But copper is still
common inside houses - although push fit plastic is a popular DIY option.

there's a couple of points that I would value your input on.

Organic compounds go straight through plastic pipes, so if you spill
petrol, or diesel on your drive, and the pipe is underneath, expect
your chances of not getting cancer to decrease.

Our habit of building new houses on old factory sites, (where did they
tip those heavy metal wastes/pickling acids etc?) worries me a bit
too.

Luckily, the Alzheimers from all the aluminium drinks cans, and those
battered jugs we kept the water in at school dinners means I soon
forget about

I'm also a believer in copper. And actually enjoy plumbing.

Given the amount of plastic packaging used for food and drink this is a
bit of a worry...

For a while we were allowed to use PVC for water plumbing, but after
many failures it was banned for use with pressurized water.

I believe the stuff we have buried outside to the houses is still some
sort of plastic, it's probably the same stuff as over there. Inside the
house it's all copper in most houses though, that's my favorite type of
plumbing to work with.

Roto=rooter replaced the line (galvanized iron) between two buildings on
my property with PVC. It worked fine for the five years we owned it.
However when the main from the street ruptured, I researched local codes
and replaced with hard-drawn copper...the only legally acceptable choice
here in Nashville. I believe the local codes are simply a rubber-stamp
of the National codes.

I did all the excavation and had licensed plumbers come out and make the
connections...also legally required.
