RoHS solder - which type?

[Spehro Pefhany]

Just starting to play around with this stuff.

I picked up a roll of 0.8mm Sn99.3 Cu0.7 solder on spec, and to my
surprise it solders just fine on my WTCP iron with a '7' tip.

It just looks rather crappy when it solidifies- a bit like a cold
solder joint. Still, not that bad.

Is the tin-bismuth alloy solder any better or worse?


Best regards,
