    Sounds like we might be from the same background. Training school at
    Poulton-le-Fylde near Blackpool, by any chance ?

    Ah, right. I was one of the 'Redi Boys' that's Rediffusion. Eventually,
    Granada took us over, but I was long gone by then.

    Well, it seems that info was also bad. I called him just to find out
    what their experience had been so far and found that so far they are
    still exempt They have not made the switch.

    Thanks for your understanding. I was very reluctant to admit my
    mistake, but I felt that it was only fair to keep the discussion
    honest.

    The whole situation has become very complex, with two technologies now
    competing on geographical grounds. I guess if all your work, and that of
    your friend's place, is US based, and not for export over here, then you
    have no need to switch to RoHS approved components and solder, except maybe
    on the grounds of the caveat regarding not mixing solder types. By this I
    mean that I guess gear manufactured in lead-free technology is pouring into
    the US from the far east, but the fact that you have no *requirement* to
    preserve its lead-free status, probably means that it is getting repaired,
    for the most part, with leaded solder, which may not be the best thing for
    long term reliability. Not that this technology is reliable in the first
    place, of course ... !! d;~}

    I certainly don't know all the legal ins and outs, but my previous
    employer certainly made things that were shipped to all parts of the
    world. It was custom scientific gear, however, and certainly not any
    kind of a commercial mass-marketed product, so it remains exempt. They
    report that the exemptions get stricter every year, so they expect to
    have to deal with RoHS eventually and are just hoping for now that it
    remains a far distant problem.

    My friend did check with one of the techs today and was told that they
    have occasionally had to repair lead free boards that had come as part
    of more commercial products. He reports that it was quite hard to get
    the dead RoHS parts out of the board.

    Yes indeed - for all of the reasons discussed. A lot of it is to do with
    technique using the stuff, and if your friend doesn't have cause to work
    with it much, then he will not develop the necessary skills. I have a repair
    service for a particular LCD TV power supply board which is manufactured in
    lead-free. Almost invariably, when I receive them, someone has already 'had
    a go'. So the first thing I have to do is to clean up all their unskilled
    soldering work on electrolytics and so on that they have replaced. Often,
    once this has been done, the board then works ok, so ironically for them,
    they probably actually found and corrected the original fault, and then
    destroyed their diagnostic work, by compounding the problem with
    unsatisfactory soldering - which has almost always been carried out with
    standard leaded solder, which is not only illegal, strictly speaking, but
    ill-advised for reasons discussed elsewhere on the thread.
