Lead free solder - need advice

[Olafur]

I am ordering from big web shop in Europe and I need solder wire. They have plenty of it but it's all lead free.
For soldering automotive wires and repairing (older) PCB I have used something like 60/40 or 63/37 in the past but these days seem to be over.

Should I choose; Sn96,3Ag3,7 ; Sn97Ag3 ; Sn96,5Ag3,5 ; Sn95Ag5 ; Sn99Cu0,7Ag0,3 ; Sn95Cu4Ag1 ; Sn92Cu6Ag2 ;
Sn96,5Ag3Cu0,5 ; Sn95,8Ag3,5Cu0,7 ; Sn95,5Ag3,8Cu0,7 ; Sn95,5Ag4Cu0,5 ; Sn98,3Ag1Cu0,7 ; Sn99,3Cu0,7 ; Sn97Cu3 ; Sn96Cu4 ;

Really quick and dirty web search didn't bring up much useful.

I find lead free solder needs a small about of added liquid flux to flow well when soldering. Personally I like Chipquik smd291 no clean tack flux in syringe form.

Sorry I am no help here. For electrical work, I am still using 63/37 SnPb rosin core.

Go to Ebay and look for Kester 44 Rosin core 60/40 lead solder. There's usually tons of it online.

Due to ROHS, you will not be able to order lead solder from the EU, but you can order it from elsewhere.
Do not attempt to repair lead soldered PCBs with lead-free solder. It will not end well.
