Yeah, tiny is part of the problem.

The smaller the mass of the thing you're soldering, the quicker it heats up and the hotter it gets. So, almost as soon as the solder flows, the delicate bits attached to the lug get all incandescent on you, which is generally a bad thing.

A clip of fat metal of some kind between the lug and the delicate innards will (in theory) absorb the heat before it gets to the innards. And yeah, finding somewhere to attach the clip can be a creative challenge.

This is why they make those anemic little 7-watt soldering irons for electronics applications - they give you more time between solder starting to flow and total meltdown.

Maybe you've found the reason why normal people don't try to build a foot switch for the bead roller they build when they're fabricating a hard tonneau cover for their replica 550 Spyders.
