Solder Sleeves with pre-installed Flat Braid: A preferred solder sleeve
is the Raychem S03 Series with the thermochromic temperature
indicator. These solder sleeves come with a pre-installed braid and
effectively take the place of items 5 and 6. For detailed instructions on
product use, refer to Raychem installation procedure RCPS 100-70.

Individual Solder Sleeves and Flat Braid
Solder Sleeves:
Reference the following MIL-Specs for general solder sleeves:
(M83519/1-1, M83519/1-2, M83519/1-3, M83519/1-4, M83519/1-5).
Flat Braid:
If the preferred Raychem sleeves are not being used, the individual flat braid selected should conform to
ASTMB33 for tinned copper and be made up of 36 AWG strands to form an approximately 19-20 AWG
equivalent flat braid. A circular mil area range of 1000 to 1300 is required. The number of individual
strands in each braid bundle is not specified.
Flat Braid as opposed to insulated wire is specified in order to insure
continuing airworthiness by allowing for visual inspection of the
conductor.
Secondary Method, Heat Shrink instead of Solder Sleeves:
Solder a Flat Braid (6) to the shield exposed through the window of the prepared cable assembly (4).
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 0.75" of Teflon heat shrinkable tubing (5) 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 and the Flat Braid (6) to be attached.
