Description: We don't want to hype this solder TOO much, but this could possibly be the best solder in the world. There, we've said it. This is a special blend made specifically for us and we love it. It all started as a quest to find the best solder to use in our production process and ended up being the best we've tried. The best part is that it's lead free and has a water-soluble flux core.

This package contains 1/4lb of solder and has a diameter of 0.032" (0.5mm).

Mix: 96.35% Sn (Tin), 3.0% Ag (Silver), 0.5% Cu (Copper), 0.15% Sb (Antimony).

  • A word of caution about water soluble flux. If not cleaned off with water (preferably hot) it will leave residue on your PCB that can eat away at the copper and cause trace and component faults. It is even more noticeable on fine pitch SMT components. When I used it in the past we always ran boards through a dishwasher but you can’t have non sealed parts on the boards like pots etc.

  • I bought this, but I haven’t really been able to enjoy it because it won’t flow with my iron. What’s the melting point of this solder, or I guess my real question should be what temperature does my iron need to be? I have a pretty nice old Weller iron with (according to my dad) a 700 degree (Fahrenheit) tip. I see that the copper has the highest melting point of 1,984 degrees, and the silver next in line at 1,763 degrees. Does that mean the tip has to be 2,000+ degrees, or is the concentration low enough to not matter?

    • I have had similar problems with my Weller when the tip gets oxidized. The readout says it’s heated to temp, but the temperature at the tip is actually much, much lower. Try changing out the tip and see if that fixes it.

  • What is the melting temp for this special blend.

  • Made in the USA, huh? I might just have to buy some to support whomever manufactured this merchandise.

  • This solder rocks! Love it! Best I’ve used…

  • Please post the flow temp. of your special blend!

  • Why does the MSDS state it has lead in it?

    “The best part is that it’s lead free…”

    • The MSDS states the lead (and other components) composition of a variety of products made by this company. This particular product is lead free. MSDS can be confusing at times, give it another look.

  • Noob needs guidance! Some of my joints appear to have a milky white residue after setting. What is the proper way to clean them to a shiny finish? I wasn’t too successful with water and a sponge. Thanks in advance.

    • I use warm water and an old toothbrush (but be sure you don’t use it as a toothbrush again!)

      • If it’s lead free, it should be fine to continue brushing your teeth with, no? I find that the flux helps break down tartar in some of those hard to reach places.

  • Is there a recommended temperature for this variety?

  • This package contains 1/4lb of solder and has a diameter of 0.032 not 0.020"

  • Is this rosin core, or water soluble?

  • Change text from “diameter of 0.020 (0.5mm)” to “diameter of .032 (0.81mm)”
