    I work in the industry here in US. Most work i in aerospace. Luckily most my
    ccustomers are well aware of problems with lead-free solders. I'm seeing
    more and more of them specificly specifying by contract "No Lead Free
    Solder". Even started seeing this from European customers.
  2. What problems are you seeing?

    If buying an airline ticket, for your piece of mind, specify to the
    travel company that you would like to travel by plane with electronics
    assembled using _leaded_ solder....

    There have been strong objections from aircraft builders, avionics
    makers and the military, on reliability/safety issues caused by growing
    whiskers of tin shorting out adjacent joints.

    This will not be a problem. The avionics and medical instrument industries
    have been exempted from this piece of lunatic legislation.

    Tin whiskers is one problem. That is not the biggest one tho. I've seen
    reports that none of the (common) lead free solders are as reliable: they
    fatigue quicker.
    Aerospace is very conservative. Unless there is a compelling reason to
    change something, and you can show that it works, don't change it. So I
    expect lead solder to be used for quite a while longer (if not forever)
