solder alternatives?

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 ;-)
