Will solder conduct electricity between two leads even if the leads are not touching?

I recently moved from a prototype to soldering the components. This is a very compact application, and I'm thinking some of the leads are not actually touching (which is why it isn't working), but the solder still provided a strong bond. Should the leads always be touching in order to eliminate a poor (or no) connection? Also, would it be poor practice to use a small snippet of 20 gauge wire as a "crimp" over two leads to ensure connectivity, or would this only complicate matters? Thanks!

Yes, but not as well as copper and solder's resistance may adversely affect or degrade the electrical signal.
If you're using the "snippet" to ensure the leads of the component are making good contact, that's no problem. If the "snippet" is acting as a bridge between the leads, then you are just complicating the connection.
Best best, make sure the leads are in good, solid contact and just solder them together.

Yes. However, solder has very limited mechanical strength, so it's best to contact the wires using a standard binding method prior to soldering. (twisted together, jhooks, etc.)

A good solder joint is undetectable from wire to wire contact.
