SolderSleeve One-Step Wire and Cable Terminators
Installation Procedures for CWT and B-155 Products
1.0 Introduction
SolderSleeve one-step terminators provide electrical termination in a wide variety of
interconnect applications. One-step terminator capabilities include terminating wires to
component terminals, ground wires to cable shields, terminating coaxial cable, and wire-to-
wire splicing.
A precisely engineered, fluxed solder preform within the heat-shrinkable thermoplastic sleeve
provides a completely soldered, strain-relieved, encapsulated termination. The one-piece
design of one-step terminators simplifies installation, while their transparent insulation sleeves
make inspection easy.
2.0 Application Equipment
Equivalent tools may be used.
Steinel HL-1802E, HL1910 IR-550 Mark II Infrared Heating Tool
or HL2010 Hot-Air Gun MiniRay Infrared Heating Tool
CV-5300 Hot-Air Gun Process Belt Heaters
CV-5000 Thermogun Holding Fixture AD-1319
AA-400 Superheater
3.0 Part Selection, According to Application
Select correct part number from the SolderSleeve One-Step Wire and Cable Terminators
Selection Guide (H54335) or consult the technical data sheet (or Specification Control
Drawing) of the product (shield terminations, wire-to-wire splices, wire to component
terminals or for coax terminators).
4.0 Termination Procedure
WARNING
Follow installation instructions carefully. Use adequate ventilation and
avoid charring or burning during installation. Charring or burning the
product will produce fumes that may cause eye, skin, nose and throat
irritation. Consult Material Safety Data Sheets RAY5103 (for CWT products)
and RAY5104 (for B-155 products) for further information.

• For a small gauge wires, (up to 1mm
2
), and when a mechanical attachment is required,
secure the 2 wire ends, by twisting them together. Align carefully the strands in order
to avoid any poke through of the sleeve. See Fig. 1 and Fig. 2.
In other cases, align wires in such a manner that all strands are parallel.
Then, slide the sleeve over the splice area and center the solder preform of the sleeve at the
center of the splice length.
Fig. 1
Fig. 2
2.
The splicing operation is made easier by using the recommended holding fixture
(AD-1319), keeping the wires aligned and the sleeve positioned during the termination.
3. Heat solder preform until it melts and forms a fillet between the conductors.

Note:
For making connections directly to printed circuit boards using CWT-38XX-W3 or
B-155-38XX-W3 part numbers, use cable preparation described for shield termination in
Section 4.1. Adjust strip length of center conductor to accommodate desired spacing between
PCB mounting holes.

1. Position the smaller or center conductor one-step terminator so that the end is against
the folded shield, and the solder preform is visually centered over the exposed center
conductor.
