Precision Die-Punch for Trimming the Conductors of Flat Conductor Cable 
A precision die-punch will trim the conductors of 
FCC to a width of 0.040 in., adapting the cable for 
termination with a standard FCC plug which em-
ploys a window piece with 0.048 in. openings and a 
conductor spacer with 0.044 in. wide slots.
Before insertion into the die-punch, the cable is 
cut square and stripped with a stripping tool. An 
adjustable guide, flush with an edge of the cable, is 
moved right or left until the center of the insulation 
(between the most central conductors) corresponds 
with the registration mark on the die. The registra
-
tion assures that the conductor material is trimmed 
symmetrically from each side of the conductor when 
the punch is lowered and raised. This operation 
trims each conductor to a width of 0.004 in. and 
consistently leaves 0.035 in. spaces between adjacent 
conductors.
