connection contamination soldering insulated wires

robogary
robogary over 1 year ago

I bought a some devices for my current E14 project that came with 30 AWG pigtails.

The pigtails were about 3 inches long with about a 1/16th inch stripped on the end.

All the different techniques of joining 2 ends of wire before soldering look great, until you are working with 28 or 30 AWG wire. 

I did what I could to make a perpendicular leg with the pigtail wire. The extension wire I stripped a bit further, enough to make a hook, and kinda crimped the hook around the bent wire. 

The third hand clamp was absolutely necessary. Once the wires were hanging from their almost hooks and sorta loosely crimped, I touched with solder and aligned.

Even being quick and careful, the wire insulation was right in there with the hot solder joint and in some cases contaminating the solder joint.

Anyone have detailed experience with the integrity of a small wire solder joint contaminated with insulation ?

    30 AWG wire is my favourite choice for board-level connections such as bodge wires on PCBs or point-to-point wiring on a board when prototyping. Often it is silver-plated, and solders well. If it is oxidized…

    A lot depends on what it is. PTFE can be difficult to strip but tends to stay the same shape while soldering the wire. Watch out for fumes though. I often use a pair of 'Helping Hands' with thin wire,…

    A close inspection of the joint with high magnification is likely the easiest way to get a feel for the quality of the joint. A picture would help. Flux is useful for joints like this.
