What solder should I use?

[ramiroelliot]

I currently have 0.6mm lead-free solder with 2% flux, but I was wondering what other people used to build their pedals. I can see that a lot of people prefer leaded solder, but I'm also curious about thickness. Is 0.6mm too thin? Does the thickness matter? I'm doing perf board soldering.

Same here, Kester 44. I use .5mm in order to do the occasional SMD things. It needs to be flowed in fast for bigger joints.

I also use Kester 303 (water soluble) in .8mm for a lot of stuff, mostly because I still have a lot of it. I think I slightly prefer the .5mm but I don't plan to try anything thinner.

I've also got Kester 44 63/37 at .020 for nearly everything.
