Flexible Interconnections

Flexstrip

ESCRIPTION

PPLICATION

FLEXSTRIP

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.

FLEXSTRIP

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.

FLEXSTRIP

JUMPERS

ESIGN

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.
