    Is anyone using voc free, leadfree solder in there wave process??
    Like to discuss some things about it. I have 25 years in the
    manufacturing of printed circuits.
    This process is much more diffacult than they lead us to beleive.

    Surprise !

    Lead-free solder is junk.

  4. Of course it is. OTOH its the stupid idea of some crackpot European
    beuracrats that don't know a damn thing about metallurgy, yet are busy
    screwing the entire world in their half assed attempt to keep any
    foreign electronics from being imported.

    Don't you also have some pretty draconian and nonsense lead regulations over
    there too, Michael ? I seem to remember reading that there are regulations
    regarding the disposal of CRTs now due to the lead in the glass faceplate.
    The whole world is going mad ...

    If you're not under pressure to go lead-free on your solder already, trust
    me, it's coming ! The whole of the far east's production for europe is now
    done in lead-free, and I guess they just ship the same basic products to the
    US also. I can't imagine them running parallel leaded and lead-free lines,
    and component inventories. Is the stuff that you guys are repairing now
    built in lead-free, and what are your experiences of it so far ? Have Sony
    insisted that their gear is repaired with lead-free components and solder
    there too ? I'm assuming that you don't have any actual legislation yet that
    compels you repair in lead-free ?

  6. One of the talking heads on the TV news was yammering on about "Every
    TV ever made has 27 pounds of lead in it" I have TV sets that only
    weigh a few ounces. Where the @#$%^ is the rest of my lead? ;-)

    it turns out that when the EPA calculated the amount of lead in the
    glass of a CRT, they ground it to a fine powder before using acid to
    separate it from the dust, then multiplied the amount by a huge number.
    Its as phony as Global cooling/ warming/ climate change. :(


    CRTs are supposed to be returned to the manufacurer, still under hard
    vacuum. WTH are we supposed to do we do with broken ones, or gassy
    tubes? I say we load all the crappy CRTS, and scrap electronics in
    resurrected B52 bombers and drop it on the Chinese factories that keep
    spewing out this crap.


    No, but its getting a lot harder to find components that are tinned
    with real solder. I have some nice tin/lead/silver solder for the fancy
    work, and some older Ersin Multicore .031" 60/40 for regular work. With
    my current health, it looks like a lifetime supply. The equipment I
    worked on before becoming disabled was exempt, being that 95% of it went
    to government agencies around the world. If they insisted on lead free,
    we told them to get lost. its amazing how fast you get an exemption
    when they NEED your custom built equipment.

    That situation is much the same here, with avionics, military and medical
    having exemptions. I'm not sure about civils like the emergency services. We
    are just going over to a 'secure' comms system here for emergency workers. I
    wonder which technology their new kit is built in ?

    Yep, that's the method of determining the amount of lead in the glass that I
    read about. See ? You're closer to being like us over there, than you
    thought d;~} !!

    On the global warming front, it's funny to see how an idea can gain
    momentum. 35 years ago, all the talk was of us being about to enter a new
    mini ice age. I remember this very clearly, as I had my town library get me
    in a book called "The Weather Machine, and the Threat of the Ice", that had
    featured in a TV programme that was on at the time.

    Whilst I'm on TV programmes, there was one on over here on the station
    called "Channel 4" a couple of months back, called "The Great Global Warming
    Swindle". It really was an excellent and well made documentary, an hour and
    a half long, and well worth seeing if you have the slightest concerns about
    the validity of global warming, and its causes. This programme has caused
    such a furore here, that Channel 4 have now released it as a DVD. If you can
    get hold of a copy through Amazon or somewhere, I can really recommend it as
    essential viewing to get the other side of the coin, for making yourself a
    balanced viewpoint.

    It's on YouTube under "The Great Global Warming Swindle". I have it as
    one video, but it now seems to be available only as six parts.

    Water based solder would make it even more difficult :)

  11. Whatever is cheapest at the moment, of course. They don't believe it
    will ever be needed to save their lives, so they don't give a damn.


    I have nothing against most of the people of Europe, but I think they
    should pull their rabid dogs off-line. They give a bad impression to
    the rest of the world. I met a lot of tourist when I worked in Orlando
    about 20 years ago. Most of them were nice (Even if they were hard to
    understand.) but some did their absolute best to piss off every American
    they met.


    They were ranting about "The new Ice Age!!!" when i was in grade
    school. All kinds of horror stories about species becoming extinct
    because the only habitable area would be a band about 100 miles wide at
    the equator. Some were even calling for massive projects to level
    mountains and haul them to the sea to make more land available at the
    equator. they were as rabid as the Global Warming crowd, and had as
    much bad science in their propaganda. When I pointed out that the
    equator doesn't stay centered under the sun they called me a
    troublemaker and continued to spin tales of wars where everyone wanted
    that thin band of land to live on.


    I have no problem with real science, but most of what I hear is just
    wild theories. I'll see if I can find a copy of that program.

    Yes, do that. I'm sure that you will enjoy it. It features many genuine
    scientists who hold alternative views to what's being peddled as ' the
    reality of global warming ' at the moment ... Ian, above, has said that it's
    available on YouTube so I guess that's a good place to start. If you think
    Europeans in america were bad 20 years ago, you want to take a look now ...
    As you know, I visit quite regularly, and my countrymen make me cringe,
    bringing their little bits of England with them ( silly soccer shirts and
    the like ). It's too easy and cheap to travel across the pond now, so
    everyone, including those who do not know how to behave in someone elses
    country, can afford to go. Incidentally, most people in the UK don't
    consider themselves to be 'Europeans', having spent hundreds of years
    repelling Johnny Foreigner from our shores ...
