(5)
Increase the temperature until the two solder preforms are fully
melted.
(6)
Let the temperature of the assembly decrease for a minimum of 15 s
before you remove the contact from the fixture.
(7)
Check of the contact set-up.
(a) You can only set up the contact correctly if you can see the conditions that follow :
-
the two solder preforms are out of view
-
the overlap of the color conductor.
(8)
Move the braid(s) back along the body of the contact.
(9)
Cut the braid to the dimension shown.
(10)
Engage the screening feature ferrule until it touches the contact shoulder.
(11)
Increase the temperature of the screening feature ferrule until the solder is fully melted through the holes.
(12)
Hold the ferrule with a tool while you apply heat. Let the temperature of the assembly decrease for a minimum of 15 s before you remove the contact from the tool.
(13)
Check of the ferrule set-up.
____
NOTE : Make sure that the braid is correctly wet with the solder and that you can see the braid through a minimum of 2 holes in the screening feature ferrule.

BLANKING PLUGS - DESCRIPTION AND OPERATION
R _______1. General The blanking plugs installed on aircraft have the following codes: E0616 NSA938153 (ex NSA937911)
___________________________________________________________2. Connection Procedure for Blanking Plugs E0616 and NSA938153
R A. P/N Identification (Ref. Fig. 001) NSA938153 BA 2000 E0616 BB 2000 | | | | | --------- Size code | --------------- Material code | BA: Polyamide | | BB: PTFE | | BC: Thermoplastic ------------------------ Standard P/N
B. P/N Characteristics (Ref. Fig. 001)
R R R R (1) Temperature For material code BA, maximum operating temperature is 135 deg.C (275.00 deg.F). For material code BB, maximum operating temperature is 260 deg.C (500.00 deg.F). For material code BC, maximum operating temperature is 175 deg.C (347.00 deg.F).
(2) Color (Ref. Fig. 001)
C. Installation. (Ref. Fig. 002)
(1) General The blanking plugs must be mandatorily installed:
(a) In the non-pressurized zones - in all the unused cavities of the standard electrical connectors fitted with grommets.

- in the cargo compartment underfloor zones or according to
specific requirements shown on the installation drawing (e.g in
sensitive zones under floor, in cargo compartment, under
insulation mats, vertically-mounted connectors etc.)
