Jumpers are multi-
conductor board-to-board interconnect
devices, pre-plated and ready to use -
without wire stripping, cutting to length,
or solder preparation. They provide a
convenient, reliable alternative to
conventional point-to-point wiring for
high density, high-vibration PC board
interconnect applications.

Jumpers may be
repeatedly flexed without failure.
Flat/round conductor design and
one-piece
construction
give
vibration-proof reliability and longer
life than conventional wiring systems.

ESIGN
A
DVANTAGES
• One-piece construction.
• Round copper conductors rolled
flat for high flex life, tin-plated for
easy soldering.
• Round-to-flat transition zone permits
flexing stress to be distributed
evenly throughout flat conductor area.
• Round-to-flat
design
provides
vibration-proof reliability and long life.
• Round-to-flat transition zone acts
as a hinge between PC boards;
allows boards to be opened for
fabrication and servicing, then
closed for compactness.
• Round pin ends facilitate PC board
insertion and long life.
• Choice of conductor pitch to
accommodate virtually any PCB
hole
pattern;
tightly
held
tolerances.
• Available in 4 insulations for high
volume commercial use as well as
military/aerospace applications.
• Jumpers may be “connectorized”
to mate with other industry-
standard headers.
• Jumpers may be used as part of
FLEXPAC
®
assemblies.
