why 60-40 solder?

Multicore set the standard in the UK for many years and what they
suggested/supplied was what industry used. As everything was hand soldered
then,
it had to be a solder and flux with as wide an operating temperature range
as
possible.

During my brief stint in England (1977-78) I got some Multicore solder and
found it very easy to work with. Is it still available? In the USA?

Ersin Multicore Savbit, 5 core solder. lovely stuff, it has a small
percentage of copper added to the alloy to preserve bit life, and still
available in the UK.

If you wiggle the connection. you have a lot better chance
of making a connection with 60-40. First thing I think of.

Well, maybe I'm wrong.
One way to find out.

huh ????

that solder has 37 % lead in it.!!!!
and thats crap , i work in a company that uses exclusively 60-40 solder and
we ship weekly 3500 pcbs a week to the eu .
where u get your info ?

Actually the importer is on the hook, not the manufacturer...

But, there are exceptions to the rule, I'm sure he fits one of them.

It is illegal to produce boards with lead, just check the internet on
RoHS. It is allowed in military applications and some medical devices
as reliability is lower.

Let's be clear that the United States has less stringent regulations.
AIUI, commercial (as opposed to consumer) boards for sale in the U.S.
may still use leaded solder.

As far as Mark's belated entry into this old thread, I assume he's
trolling.

I think it's perfectly legal to rework boards using lead/tin solder if
the boards were originally produced with it and because of that you can
still buy led/tin rosin fluxed solder.

Hmm.. I didn't realize that there were any regulations on leaded solder here
in the USA. I just thought we got consumer grade crap that was manufactured
for sale in the EU that happens to be ROHS compliant.

Ditto. I'd love to know about any laws banning leaded solder in the USA
so I can get a jump on starting my new multimillion-dollar recycled home-
electronics business.

ah-so. Apparently my confusion on this issue hasn't worn off yet.
*Somewhere* I thought I heard that consumer grade electronics had to be
RoHS compliant, but it might have been a dream...

I do know that California has some RoHS restrictions. I also know that
several of our customers who market globally require us to comply with
EU RoHS assembly standards so that they can market worldwide without
trying to keep track of which unit has lead and which one doesn't.

So it's likely that even stuff manufactured in the U.S., for sale in the
U.S., has the feared lead-free solder in it.

I saw an article the other day that said that Arnie had personally blocked
some lead-restrictive potential legislation in his capacity as governor of
ca. Ah I've just found it. Don't know if it will make it through the
newsgroup server system, but here it is copied below ...

California vetoes ROHS-expansion bill
Edited by Suzanne Deffree -- EDN, 1/10/2008
California Governor Arnold Schwarzenegger has vetoed an assembly bill that
would have more closely aligned California’s ROHS
(restriction-of-hazardous-substances) law and regulations with the EU
(European Union) ROHS directive. The bill, AB 48, would have expanded
California ROHS to include all electrical and electronic equipment, as
opposed to its current requirements for “covered electronic devices,” which
include nine video-display devices that the state’s Department of Toxic
Substances Control regulations list. The bill also aimed to require that all
electrical and electronic equipment that manufacturers sell in California as
of Jan 1, 2010, comply with EU ROHS stipulations for lead, mercury, cadmium,
and hexavalent cadmium.

Schwarzenegger sent the bill back to the California legislature in the fall,
stating in a memo that the bill’s approach “is largely unworkable and
instead of the benefits it seeks to accomplish, could ultimately result in
unintended and potentially more harmful consequences.”

The governor noted the exemption language for spare parts and refurbished
products, claiming that, as written, the bill would make many electronic
products prematurely obsolete and force their retirement years earlier than
necessary. The California legislature is expected to try to pass this or a
similar bill again in 2008.

Showing that Arnold is not just another pretty face. Implementing RoHS
as mandated by the EU for solders may actually cause the release of greater
amounts of toxins into the environment than use of traditional lead-tin
alloys. There have been studies that address this issue, and the "benefit"
of EU-style RoHS is far from clear and certainly not unalloyed (pun intentional).

So EU-style RoHS regulation for solder:
1) results in poorer quality products
2) may actually worsen the environment relative to what would be with use of lead-tin
Sounds like typical politco-think. Jump too soon on some bandwagon because it sounds
good, then refuse to even look publically at the evidence that perhaps it was a mistake.
Just quietly grant exemptions to pressure groups with enough lobbying clout or soft
money ...

Politicians, Bah Humbug. (And, yes, I vote; not just complain.)

As 99% of electronics that consumers buy originates in places other
than in the USA you'll end up with exactly the same Chinese, Korean
and Japanese crap that RoHS has forced on Europe, it might have some
RoHS components, it might have lead free solder but it will have what
the production plant has to hand and what stickers they have. You CAN
pay for proper quality control but it costs. Produce it within your
own borders and you might end up with something that will last, but on
the downside it will nearly always cost ten times as much as the
import.

It is impossible to get it through thick politicians heads that
solidly built equipment with 60/40 solder and replaced every 10-20
years is much better for the environment than stuff that barely makes
it into the consumers home before going completely tits up.

I'm still using the same amp and turntable I bought in 1980, the same
CD player I bought in 1987, the same main TV I bought in 1989 and the
same portable TV I bought in 1980. The VHS Video I bought in 1983 was
only recently retired with the purchase of a Digital Terrestrial Hard
Disc Recorder. I doubt it will last 10 years let alone 25.

Other than a few caps, the odd semi and a few dry joints, they haven't
really needed any major work. I reluctantly threw out a couple of
17" monitors last week - down the dump there was a huge pile of
discount shop brand TV's that looked at the most a couple of years
old.
