Sculptured Jumpers
Flexible circuit technology incorporating rugged termination features
General Description
A general purpose interconnection system using established Sculptured circuit
technology which combines maximum flexibility with rugged termination features.
|
Benefits
- Space and mass savings
- Standard jumper lengths up to 101.6mm (4 inches)
- Custom jumpers on request
- Hand, wave or reflow solderable
- Differential conductor thicknesses combine flexibility
with rugged terminations (see figure 2)
- Straight or formed fingers for surface mount or through
hole soldering
- Elimination of connectors
- Plugs into standard sockets
- Superior current carrying capacity and heat dissipation
- Good flexibility
- No tooling charge for standard jumpers
Termination Fingers
Sculptured jumpers feature unique integral termination fingers for maximum
strength and reliability. (See Fig 2) These can be formed in various ways.
Connectors
Sculptured jumpers are suitable for use with many standard PCB-mounting
socket headers. (See Fig 3)
Design Tips
- When required, fingers should be formed prior to solder
assembly and it is normal for this to be undertaken by Teknoflex on your
behalf.
- For ease of assembly a maximum cable width of 75mm is
recommended
- Include a 10% service loop in the cable length for strain
relief
- Wherever possible it is cost effective to specify one
of the standard insulation lengths. These sizes, which are available with
a 2.54mm (0.1 inch) pitch and without artwork design and tooling charges,
are detailed opposite.
- Consult our engineering team and/or refer to our Designers
Guide during the design process.
Options
- Pre-tooled standard jumpers are available
- Surface or through hole mounting
- Standard jumper lengths to 101.6mm (4 inches)
- Custom jumper lengths to 558.8mm (22 inches)
- Conductor pitches down to 0.635mm (0.025 inches)
- Polyimide, Polyester (PET), Polyethylene naphthalate
(PEN) dielectric films
- RoHS compliant electrolytic matt tin standard finish. Other finishes to order
- Custom finger patterns
- Raised contact points (RCPs)
- Surface mount interconnects (SMIs)
- Flame retardant dielectric materials.
