(2) Push the solder sleeve over the exposed shield braid so solder sleeve shall
be approximately centered over the exposed shield braid.
(a) To avoid heat concentration which might split or otherwise damage
the solder sleeve, the end of the shield ground wire insulation, if not
preinstalled, should be positioned approximately even with the inner
edge of the seal ring.
(b)
Maintain the relative position of the solder sleeve, shield ground
wire and shield braid during assembly.

(c) Use tinned copper braid Alpha P/N 1223 (3/64 inch) or equivalent
for pigtail. Lap pigtail braid or wire segment with wire shield and
place solder sleeve over assembly.
(d) Shrink the solder sleeve in accordance using infrared or hot air
heaters. Apply the heat uniformly, periodically rotating the solder
sleeve during the heating process. Do not allow the infrared or hot
air heater to touch the solder sleeve or wire during the heating
process (touching of the heating guard is acceptable).
(e)
Inspect for conformance to criteria for installed solder sleeves per
the following:
(i) No appearance of the solder perform ring will remain.
(ii)
In the case of solder sleeves with indicator rings the
following also applies: It is necessary that the indicator ring
has completely disappeared or melted.
NOTE: If the process continually results in less than 100 percent
melting of the indicator ring there may be a problem with the
process which should be corrected before further
processing.
– If infrared heating is used, the problem is usually caused
by a dirty reflector.
– If hot air is used, the sleeve may not be centered in the
hot air reflector.
