Secondary Method:
Solder a Flat Braid (item 4) to the folded back shield on the prepared cable assembly (item 2). Ensure
a solid electrical connection through the use of acceptable soldering practices. Use care to avoid
applying excessive heat that burns through the insulation of the center conductors and shorts the
shield to the signal wire. Slide a minimum of 0.75 inches of Teflon heat shrinkable tubing (item 3)
onto the prepared wire assembly and shrink using a heat gun. The chosen size of heat shrinkage
tubing must accommodate both the number of conductors present in the cable as well as the Flat
Braid (item 4) to be attached.
Teflon Heat Shrinkable Tubing:
Reference the following MIL-Spec for general Teflon heat shrinkable tubing
(M23053/5-X-Y)
