Tried awg 28 solder (28 guage wire width) ?
I got myself some kester  RMA FLUX 28AWG 63/37 
comes in 2.2 kg(1LB) pack. (not cheap but worth it).

Any similar sized (fine)solder should be fine.

What iron tip size are you using ?

And what method are you using ?



No don't use a normal iron with solder paste.
You will end up with a big mess.
