You really should do a Google Groups search before asking.

** The amount of work has increased.

Pb free solder is often brittle and cracks easily under thermal cycling,
stress or vibrations.

Standard procedure round here is to remove it with wick and use some real
60/40 Savbit solder to make the repair.

Arent't there some legal issues with that?

**You tell us - fuckhead

But round here = Australia where the RoHS directive is not law.

Nor is it law in Japan, North America and most places.

And would not give a shit if it was.

This week a 6 month old amp with 2 separate PbF faults found. Plus loads of
other problems. Test with dummy load , then speaker. Place back in the cab
and supposed final test - another damn intermittant fault. Maybe just
induced by my localised handling on the power amp is enough to have
disturbed another only just holding lead-free solder joint. Luckily the
owner has another amp he cab use and this one can sit until next week when I
may be in a calmer frame of mind .

Of course. The increased number of failures due solely to solder
joints has kept many a service department busy. Reworking with
"decent" solder is the simplest treatment.

I've still not found out what they do in the automotive industry, re
electronic engine management etc. All components will have that "lovely"
mirror finish of tin tinning on all leads plus lead free solder? AKAIK they
do not have a derogation to use proper solder. Cars are parked often in sub
zero temperatures to start tin-pest and then extreme heat cycling and
vibration is use, next to an engine ,is guaranteed to crack PbF. Toyotas
,with a mind of their own , comes to mind.

Finally a fairly civil post that I can agree with from you.
I know it's just bait and tomorrow there will be a subject
Meat Plow is a MORONIC FUCKHEAD but we're very used to it.

The lead free solder flows at higher temperature than lead. So you have to be careful the heat you put on the components you're soldering.
The original reason for lead in solder, was to prevent conductive 'whiskers', which grow
from the structure of tin. This can be important in very low voltage, current devices.
The compromise was apparently ok with modern devices (getting rid of lead), because
it was reasoned that today's devices are cheap throw-aways, and the whiskers won't
form in the three years of the useful life of the device, before you toss it.
I'm old enough to remember the engineers doing studies on the effects of whiskers, to
extend the lives of the company products. Something that manufacturers don't worry
about anymore.

Well....
I found this:
Begin quote
.. I don't know whereabouts in the world you
are, but across Europe, strictly speaking, it is actually illegal to use
leaded solder, or non RoHS components, to repair anything manufactured in
lead-free after implementation of the RoHS directive, which was June 2006 (I
think) in the UK.
end quote.

so I asked...rather politely...I think...

I give the above quote more credence as it is not riddled with name calling
and four-letter terms of endearment. Also, the tone is quite civil.

Hmmmm...civil...I should find a word with which you'd likely be
familiar? It's about being nice to people.

Note that I didn't ask if YOU cared. I asked if there were issues.

No, just trying to learn. Why would you think that, BTW?
As to the other denizen with an itchy flame-thrower finger, of course I
Googled before posting here.
Newsgroups are getting awfully twitchy these days.

Well....
I found this:

** Totally asinine to post an unidentified quote.

How like you.
I give the above quote more credence..

** It says nothing different to my post.

I live in Sydney, Australia you know.

Note that I didn't ask if YOU cared. I asked if there were issues.

** I were given a precise, detailed reply that when right over your pointy
head.

Piss off TROLL.

** Find me one example of a person being successfully prosecuted over it.

There is virtually no way to get caught, no easy way for outsiders to know
and nobody gives a shit.

Not in Europe it isn't. There are heavy fines for doing that.

** The fines may exist in theory, but can you show if anyone has been fined
for using the wrong solder for repairs ?

There are many obvious, simple defences to such a charge and almost no way
to get caught.

Get real.

For the UK, section 14 of the RoHS Regulation

A producer putting non-compliant EEE on the market on or after 1st July 2006
shall be liable on summary conviction to a fine not exceeding the statutory
maximum, which the Home Office says is currently £5,000. Or "on conviction
on indictment to fine" - there is no statutory maximum.

Producers failing to provide documents showing compliance within 28 days of
an official request shall be liable on summary conviction to a fine not
exceeding level 5 on the standard scale. Level 5, coincidentally, is also
£5,000 at the moment.

Failing to retain technical documentation for four years after EEE has been
put on the market is also a not-exceeding-level-5 fine.

EEE= electrical and electronic equipment
