R  (Ref. Fig. 005, 006, 007, 008, 009, 010, 011, 012, 013, 014, 015, 016, 017, 
R  018, 019) 
R 
R  - Move the selected sleeve horizontally along the coaxial wire and bonding 
R  wire assembly. 
R 
R  - Turn the sleeve as it moves along the bonding wire to make sure that it 
R  does not catch on the strands. 
R 
R  - Center the solder preform on the stripped part of the bonding wire and 
R  shield. 
R 
R  - Install the assembly in the applicable tool but do not turn it. 
R 
R  - Heat the center of the sleeve until the sleeve shrinks :
 the solder ring melts and flows into the strands of the bonding wire and
 shield and the sealing rings melt and flow.
 The collapse of the solder ring does not show solder flow. Continue to
 apply heat until the solder flows into the strands. 
R 
R  - Let it become cool for a few seconds before you handle it. 
R 
R  - Make sure that the solder sleeve is correctly shrunk (Ref. Fig. "Defects
 representation"). 
R 
R  - Do a check : 
R  .that there are no balls of solder, 
R  . correct shrinkage of the sleeve (no flaring), 
R  .that there is no overheating, 
R  .that there is no solder rejection (cable SJ and ST ...). 
R 
R  - Insulation procedure (for wires HG and WC only). 
R 
R  For wire HG (Method F)
 Install the shrinkable sleeve (detail F6).
 Retract the sleeve. 
R 
R  For wire WC (Method G)
 Strip the triaxial wire conductor.
 Install the three shrinkable sleeves (1), (2) and (3).
 Retract the sleeves (1), (2) and (3) (detail G3).
 Attach the two bonding wires with the cable tie (detail G2).
 Install the shrinkable sleeve (4) on the two ferrules.
 Retract the sleeve (4) (detail G4).
