Lead free solder - exposed in a UK national newspaper

    What exactly can be recycled from say a PC?
    As far as I can see the steel casing and perhaps some copper if it is not
    too widely distributed , fragmented, needing human separation and plastic
    separation environmental problems.
    RoHS for recycling implies component level recycling - recycling 3 to 10
    year old pc ICs - pull the other one.
    Failing that, recycling processed sand and hard plastic after desoldering,
    very unlikely. Leaves just the solder itself, which is just as recyclable
    with or without lead presumably .

    That would appear to me to be the nub of the matter, so it sounds as though
    you agree with me that this 'ease of recycling' thing is a subtle shift of
    tack to better handle the changing wind direction ...

    I know that they do recover gold from gold-plated connectors and IC pins,
    but other than that, I agree that there's not a lot that can be recycled
    from a purely practical point of view in terms of cost-effectiveness, both
    from purely monetary and energy budget considerations.

    A couple of microns ?
    Since when have "IC pins" had gold on them ?

    Indeed and it seems almost no-one in Europe wants to touch the stuff. Trying to
    'recycle' electronics pcbs strikes me as an utter waste of time. What do end up
    with of any use ? Nothing !

    Since they put about a million of them on the bottom of a big chunk of
    ceramic, called it a processor chip, and then tried to persuade all those
    pins to make a good electrical connection via a ZIF socket ...

    I saw a TV programme about a facility in the UK that recycles computers, and
    removes the gold from various bits and pieces at a 'secret' location, and I
    was astounded by the amounts of gold that were recovered, that not only made
    this worth it from a recycling point of view, but also extremely financially
    lucrative for the company doing it.

    Take a look at this link for more facts than I could give you

  5. We buy and use IC chips with gold pins, which we form, and recycle the
    cut leads from.

    You are only about three decades off, and the industry has NOT stopped
    using them.

    Mil spec parts have gold all over the connection wires and leads on
    many of the devices made out there.

    Since the advent of COTS, designs typically incorporate both mil and non
    mil parts together to complete a design for a contract.

    In other words... whatever it takes to get 'er done!

    I have more than one co-worker with a car with LED headlights.
    Infinity, Lexus, BMW and others do this already.
    I have LED bicycle headlights myself.
    And the last is a nice change from jumbotrons.
