Best way to solder small wires. Wrap a bit of the 30AWG wire in a spiral around the 20AWG wire and solder. Put a bead-sized amount of rosin flux on your finger and rub it over the exposed wires. Try to coat the wires as evenly as possible so theres a thin layer of flux on them.

The shrink tubing has hotmelt glue on the inside and once you apply heat to the center solder band the solder melts the wires are held firmly in place the glue melts then the shrink tubing draws down on the wire.

Then I take fine stranded wire and pull out one strand. This is often used in aerospace but is the worst for solder. Put rosin flux on the spliced wire to help the solder adhere better.

I will be using a power probe butane soldering gun. BTW the wire shown in the OP photo appear to be silver plated PTFE insulated. If you did the cable and the tag at the same time by the time the solder properly melted the wire insulation would have started to melt.

Clean about 01 inches of insulation and carefully tin it. This will help conduct heat to the wire. Sold in the electronics department.

Soldering small wires to very small connections such as unused pins on QFPs First tin the connection point. Ad Quality Solder Wire Drawing Machine. This has a smaller metal area so wont need as long to melt the solder This time I usually put the wire through the hole in the tag and bend it slightly inwards.
