Is the wicking of solder down the wire causing a rigid wire for the first inch or so preventable? Besides a pull test, is it possible to visually recognize a poor solder connection? -------- Michael Fleming Read this topic online here: http://forums.matronics.com/viewtopic.php?p=499385#499385 ________________________________ Message 2 _____________________________________ Time: 01:28:16 PM PST US From: Art Zemon Subject: Re: AeroElectric-List: Soldering Big Connections Michael, Bob's instructions are super complete and very detailed because that's what Bob does so well. I followed his instructions and have now attached two whole connectors so I consider myself an expert. :-) I can tell you that the process was much simpler and less intimidating that it seemed from reading the instructions. I stood my propane torch up on the table. That left me one hand to get the connector only near enough the flame to melt solder and a second hand to wield the solder. I melted a ton of solder into the connection and, when I was done and things had cooled down, it felt mechanically quite secure. This is a very low risk project. If you try it and get poor results, all you have wasted is a bit of wire and a cheap connector or two. If in doubt, use a short scrap of wire and practice a time or two. -- Art Z.

Remember, *all* joints have stress risers; even crimped joints using PIDG terminals. The metallic insulation grip and the extended nylon terminal insulator assist with moving the bend (stress) point away from the crimp point, but the wire still needs external support. With a little practice/experience, you can ID an obviously bad solder joint, but if you start with clean conductors and terminals use a bit of electronics-type flux, and keep the wire/terminal stationary while it cools, you'll likely be fine without the ID experience. An obvious bad joint will often have a rough, dull gray, almost porous appearance on the exposed solder, and will sometimes have a convex appearance rather than concave at the point where the solder meets the copper, where the exposed solder looks analogous to a ball of mercury sitting on a surface instead of flowing out smoothly to meet the surface of the copper.

Wrap a band of conductive metal (aluminum is good) around the insulation up close to the fitting and clamp it in place. This forms a heat sink. 2. Use minimal solder flux only on the portion of the bare wire that will be inside the connector. 3. Crimp the connector to remove air space. 4. Add heat and solder from the far end of the connector (end opposite the insulation) only. 5. When the temperature is right the solder will draw into the connector. 6. Stop adding heat and solder when the solder arrives at the insulation. 7. It's OK to quench in cold water. Cheers!
