16. CABLING TERMINATION
A. General
(1) Terminate all individual cable shields which are not “dead ended” using a
solder sleeve and braided pigtail (equivalent in cross section to shield braid
with center conductors removed) or optionally the braid pull-out method.
Use the smallest solder sleeve that will fit over the cable shield and the
braid pigtail.
(2) The shield pigtail may be either a wire segment (of sufficient diameter
equivalent to shield braid with center conductors removed) or another small
braid segment. Wire segments are used when the cable shield is
terminated to a connector contact or a terminal lug. Braid segments are
used when the cable shield terminates at a back shell or EMI spigot,
terminal lug, or split support ring used to terminate a braid sock. ZAP
assemblies with multiple terminations may use either wire pigtails, braid
pigtails or a combination of both.
(3) For back shell shield terminations, the individual cable shield shall be
terminated at the end of the cable maintaining the minimum length of
unshielded conductors with the shield pigtail installed at the back end. The
solder sleeve may end up inside the back shell depending on the length of
the unshielded portion of the cable.

B. Solder Sleeve Assembly
(1) Remove the outer jacket using a thermal stripper or other suitable means,
exposing 0.25 to 0.38 inch of shield braid.
(a) When using a suitable tool other than a thermal stripper to remove
jacket, score jacket lightly and bend cable to complete jacket
separation. Do not cut completely through cable jacket.
CAUTION: Cutting through the cable jacket may result in damage to shield.
