This is the Spektrum Soldering Jig
While soldering might not be every hobbyist's favorite task, Spektrum developed the Spektrum Soldering Jig to make your life easier. This jig features an adjustable and movable alligator clip to hold wire exactly where you want it.
Both male and female ends of IC2, IC3, and IC5 connectors are embedded in this jig, so simply plug your connector in, and solder away.
Plugging your connector into the opposing style connector keeps your connectors from warping due to heat or moving allowing you to solder with unmatched precision. As a bonus, this also holds 2.0mm to 7.0mm bullets for easier soldering.
