solder alternatives?

[Mark Haase]

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,
mark

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
somesuch.

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 ;-)
