So I had heard that for PTH soldering flux isn’t needed, but, hell if I can manage it. I use and abuse that flux pen I’ve got to get things together nicely. I’m thinking it might be that I’m using wire cored with a no-clean flux so maybe that’s the problem. (Kester 275, lead-free)So, what’s your favorite solder and why? Is no-clean a scam? Yeah yeah, I’m probably going to get crap for going lead-free but it’s a bit of a preference.
With PTH soldering flux is a must (dipping). If hand soldering most roll solder has some kind of rosin core which provides the flux.
If your want to go lead-free “multi-core” solder is the way to go. I think they have the best lead-free solder for hand soldering. It is more expensive, but if you have a nice soldering station (really needed for lead-free), you will never regret using multi-core solder.
Just as a note. The only place in the US which I have found sells it, is Newark. They like all their products, so be prepared for the price.
