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 

contact (IDC) connector terminations. It is critical to remove the foil covering 

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.

Set blade depth

 (See Figures 4 and 5)

a.

   Lock a test sample of cable into the Upgraded 

Carpenter Model 47 using Handle 1

b.

   Open micrometer just more than cable height 

c.

   Close micrometer a small increment and  

slice blades using Handle 2

d.

   Cycle Handle 3 to test strip foil covering

e.

   Open blades, remove sample, and  

inspect per guidelines below

f.

   Repeat steps c, d, and e until foil  

covering is removed but insulation  

is not damaged
