Best halide-free general use hand solder?

[Mixka]

Hello everyone!

I just get my solder roll finished and are about to buy new one.

I don't remember what solder it was, because all labels are gone. All I can remember is that it was containing some amount of silver and it was halide-free, because I can't stand it.

I look Mouser, TME, Farnell and RS Online and these is what I found:
Stannol 810691 (5,50€/100g) Sn60/Pb40 F-SW33/REL0 Crystall/Kristall 400 (multicore 2,2%)
Stannol 640053 (5,50€/100g) Sn60/Pb39/Cu1 F-SW32/ROL0 HF32 (singlecore 3,5%)
Multicore 288498 (13,44€/100g) Sn60/Pb40 F-SW32/ROL0 Crystall/Kristall 400 (multicore 2,2%)
Felder Löttechnik 20.600.52037 (7,44€/100g) Sn60/Pb40 F-SW32/ROL0 (singlecore 3,5%)
Felder Löttechnik 20.720.52037 (12,65€/100g) Sn62/Pb36/Ag2 F-SW32/ROL0 (singlecore 3,5%)
Kester 24-6337-8834 (15,33€/100g) Sn63/Pb37 F-SW32/ROL0 245 (singlecore? 2,2%)

All of those is available in 0,5mm diameter.

I googled those, but can't find about anything usefull comparison or info. This was only opinion what I found: https://www.eevblog.com/forum/beginners/multicore-solder/ (Reply #10), but Stannol and Multicore have newer version available today. And I think that silver contain Felder is also new one, because datasheet don't have any mention about it.

Do you have any opinion of those or even better idea? All help appreciated!

halide-free, because I can't stand it

I didn't notice that halide-free flux fumes are any bit less nasty. Actual flux is what matters IMO, halide-free does not mean anything in this regard (unless it is some relatively active flux with high halide contents).

I agree. I still have a roll of Stannol HF34 solder on the shelf, which I could not bring myself to use up because of its extremely biting fumes. HF34 may be untypical; it apparently is a particularly active flux (based on organic acids, optimized for minimum residue on the PCB). In any case, it is halide-free and nevertheless very unpleasant to work with.

As a side note, I realized that I was confused regarding the term "halide free" vs. "halogen free", and found this brief explanation somewhat helpful:

Ok. Maybe it was just coincidence then, becouse I tried three solder before current one and all was including halides. For me, it was not just unpleasant. I got almost immediate headache, extremely dizziness and hard to breath feeling. With this halide-free I can solder all day long without anything. I have large open work place with good ventilation, but it was not helping with those earlier ones.
