I use the standard 60/40 (or 63/37) lead-based solder, with a flux pen. The solder I picked is 0.020" diameter flux core, which is kinda small but for the SMT parts I work on (0603, 0.5mm) it's just right.
You have to choose between water-clean and no-clean. No-clean is better for hand soldering, since you don't have to clean it, but two caveats: First, it conducts some electricity, and acts like a 300k resistor between adjacent traces. Don't use it for high-impedance analog stuff. Second, it's harder to clean off when you *do* want to clean it, like off stencils or sensitive analog stuff. Water-clean, however, must (should?) be cleaned off after soldering. You'll want some copper desoldering braid. I'm trying some 0.050", which seems about right, although a little smaller might be more appropriate for the parts I deal with. It comes with or without flux; get "with" - I got without and I find myself fluxing my desoldering braid to get it to work well. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
