lead-free-solder-with-silverBack when I was just a little kid, way before blogs were invented, my Dad ran a side business installing sound systems in churches. I remember hanging around and watching him solder custom audio cables at home some evenings, and for some reason, I was always dying to get in on the soldering action. It just looked fun. But far be it from any responsible parent to allow their 8 year old daughter to wield a soldering iron, so I was out of luck.

My Dad eventually wound down the custom audio work, and as a result, I pretty much forgot about soldering as less lethal-for-kids projects like friendship bracelets, crepe paper flowers and paint-your-own ceramics came my way. Fast forward to 8th grade, that magical year when public school kids get to experience the wonders of Home Ec, Sewing, Drafting and Wood/Metal Shop, all in two whirlwind semesters. When the “make-a-wire-guy-and-permanently-weld-his-feet-to-a-piece-of-sheet-metal-so-he-looks-like-he’s-walking” portion of the program rolled around, the almighty soldering iron came crashing back into my life, but this time, I was the one holding it.

It’s been around 17 years, and despite the fact that I enjoyed my brief stint as an underage solderer, what I remember most is the flux. The gunky, nasty, greasy tins of flux that we had to dunk our solder into. Without fail, we’d always use too much or too little, and would either end up with a joint that wouldn’t take, or a mess of excess flux spitting and running everywhere. But believe it or not, flux issues can get even worse.

While the excess flux issue was annoying for Junior High-aged me, I imagine that it’s even more frustrating for people who, say, make a living soldering printed circuit boards. While soldering is a vital part of electronics in general, residual flux on circuit boards can cause shorts and electrical leakage, or interfere with a board’s thermal properties. And if you’re not careful while trying to remove flux residue, even more damage can occur.

That’s why MG Chemicals’ lead-free flux-core solder is so great. Filled with a core of just the right amount of flux, this solder leaves behind a bare minimum of residue, so there’s little or no cleanup involved. Whatever flux residue does remain is hard and nonconductive, so it doesn’t carry the threats of diverting electricity or causing shorts. As a bonus, the silver-infused lead-free formula saves you from inhaling potentially harmful lead vapors, but also leaves you with solder joints that have excellent conductivity.
