General

This document covers cable preparation techniques and quality requirements

for the 3M™Round Conductor Flat, Controlled Impedance Cable, 7700 Series.

The primary cable inside the flexible foil covering is a mass-terminable ribbon

cable, constructed on a fixed-pitch interval to facilitate insulation displacement

from the primary cable only under the socket to prevent shorting. Removal of

the covering can be accomplished as described in this document or with similar

tooling and techniques.

To enhance the precision control of the Carpenter Model 47 Cable Stripper,*

a few targeted upgrades were added. A micrometer on handle number two

and bushings were added for accuracy and tolerance. The blade orientation

was flipped and the angle was sharpened to 45° to better pierce through the

3M cable 7700 series flexible foil covering. A strip length stopper has been

added to save time with cable alignment.

Guidelines

The following tips are recommended when preparing

and terminating the 3M cable 7700 series.

Preparation

• Take care to keep the new cut edge of 3M cable

7700 series perpendicular to the outer edge

of the cable for easier termination to connectors.

polyolefin insulation.

• Cycling step five 2-3 times may aid removing

the foil covering for increased conductor count

cable samples.

Termination

• Push connector outer wall flush against covering,

but leaving a minimal gap of exposed

ribbon cable.

displacement contacts.

• To maintain 3M socket assembly 451 series integrity,

excess foil covering must be removed for clearance

under socket assembly ears.

Inspection

• Insulation of exposed ribbon cable should not be

scrapped or sliced. See Figure 13.

• Any remaining foil covering on sides of prepared

cable should be removed. See Figure 14.

• Insulation around the conductors should not

be pierced. See Figure 15.
