One final note -- soldering is not gluing. It is an alloying process.

With few exceptions such as surface mount devices you should think of the solder as a conductive filler for good current flow and not a support mechanism.

Good advice to say the least. Before soldering insert-type parts be sure to clean the leads so there is no surface oxidation left. Even new parts should be prepared.
Empty PC boards should be cleaned before use to assure good solder connections. Reusing PC boards as when making changes or modifications it's import to clean off all flux residue before installing new parts. My favorite chemical is a good flux cleaner. I've included a link for one example:
