Set-up procedures for sockets, cables and guides
Standard flat cable
To assemble
standard flat cable,
the cable width is
guided between:
• The narrow end guide area.
• The side of the end guide with the viewing port
feature.
Adjustments to plate
Various adjustments are required to the locator plate,
depending on which socket connector or cable is
being assembled. 3M
™
Locator Plate 3443-94 is the
recommended assembly aid. (See Figure 1)
The Locator Plate 3443-94 can be used to assemble:
• .100" x .100" and .100" x .200" socket connectors
with and without the center bump feature.
• Socket connectors with standard flat cable and
with ground plane cable.
Ground plane cable
To assemble ground plane cable, the cable width is
guided between:
• The wide end guide area.
• The side of the end guide that does not have the
viewing port feature.
End guide set-up
To adjust the position of the end guide for the
connector length position, lift the end guide up and
move it to the left or right.
The viewing port on each end guide must align
with the appropriate connector conductor size. The
connector conductor size is specified by the numbers
on the respective labels.
To adjust the end guide position for the .l00" x .100"
or .l00" x .200" connector, lift and rotate the end
guide 180° so that the viewing port points to the
respective .100" x .100" or .l00" x .200" label guide.
Center bump feature
The center bump connector does not require any
special set-up procedure.

Shut height adjustment procedures
Assembly Press
Casting
The shut height setting is referenced in the .100" x
.200" Backplane System Chart and .100" x .100"
Grid System Chart on page l. Shut height settings are
guidelines for proper termination depth.
The shut height should be adjusted from the base
before the 3M
™
Locator Plate is put into place. The
3M
™
Presses 3316 and 3640 are adjusted with a
knob at the top of the press. The 3M
™
Press 3335 is
adjusted with the collar on the press shaft, and the
3M
™
Press 3830 is self-adjusting.
3.1
Place the shut height gauge 3436-1D across
the base of the assembly press. Lower the
handle of the press until the handle casting
makes contact with the press casting. (See
Figure 2)
Determine the type of assembly press you are
using:
• With the Press 3335, lock the shut height
adjustment collar toward the base of the
press shaft. (See Figure 3a)
• With the Presses
3316 and 3640 Presses,
turn the shut height adjustment knob until
the bottom of the press shaft contacts the
desired position on the shut height gauge.

Connector/cable assembly procedures
Grasp a socket cover strip between the
thumb and forefinger of both hands, with the
liner facing you. Rotate the outermost cover
down against the adjacent cover on the strip,
breaking it from the liner. Pull laterally away
from the strip, leaving a clean adhesive edge
on the removed cover. (See Figure 4)
Firmly press ribbed side of cable into
alignment grooves on cover. The adhesive will
help it stay in place. (See Figure 5)
Visually inspect to insure that:
• Cable is properly aligned to cover grooves.
• Cable end is flush with cover for end
terminations, or perpendicular to cover for
midspan terminations.

Place the cable/cover sub-assembly between
the guides on the 3M
™
Locator Plate, cover
side down. (See Figure 6)
Orient and position connector body —
contacts down over the cable/cover sub-
assembly, engaging cover retainer devices
with body slots. (See Figure 7)
Lower the assembly press handle fully to
complete the connection.
Raise press handle and remove completed
assembly. Visually inspect to insure that:
• Cover is fully seated and parallel with the
body.
• Cable is properly aligned with the cover
grooves.
• Cover retaining devices are completely
engaged with the body.
