    hey all--

    i have a 4 digit LED which has three pins broken off, as well as a
    68HC11 board which has a transistor that broke off. in both cases, the
    leads severed right at the edge of the package, so there's no wire
    sticking out to reattach to. i can't figure out how i would solder it
    back together, i'm guessing its impossible.

    i've seen/heard of some solder alternatives, like adhesives that are
    very conductive. can anybody comment on the appropriateness of these to
    my situation and/or recommend a good brand to buy.

    any and all help is much appreciated,

    Replace the transistor, but the LED display can be resoldered by
    cutting into the plastic around the lead and soldering, or replace
    with 4 separate digits, or fish another one out of a used clock or

    Yup, that'll work :) my personal preference is to use a Dremel (tm) to
    grind away the plastic rather than cutting it, it does less damage if
    you are careful. Wear SAFETY goggles!!!

    The other repair trick I have used is that "conductive" copper/silver
    paint (Electrocure) used for repairing car demisters. Just the thing
    for reconnecting severed leads on thin film solar cells, these worked
    100% of the time unlike the circuitry connected to them ;-)
