FFC Cable Assembly Manufacturing for Australia
Custom flat flexible cable assemblies engineered for space-constrained applications. ZIF/LIF connector selection, drawing-defined pitch, shielded and unshielded configurations for consumer electronics, medical devices, automotive, and industrial equipment.
What is an FFC Cable Assembly?
An FFC uses parallel flat copper conductors laminated in insulating film. Specify body and reinforced terminal thickness separately.
Exposed cable ends insert into board-mounted ZIF or LIF receptacles. Match contact face, terminal geometry and pin order.
Board-to-display and board-to-board links require electrical, mechanical and environmental validation for the intended application.
Why Australian Engineers Choose FFC Cable Assemblies
Review routing space, contact geometry and operating conditions before selecting an interconnect.
Ultra-Thin Profile
Check clearances for the cable body, reinforced ends, shield and connector.
Signal-Integrity Planning
Specify signals, grounds, impedance and measurement method. Pitch alone does not establish high-speed performance.
Weight & Space Planning
Compare the mass and installed envelope of the selected cable and connectors against the alternative assembly. No fixed weight saving applies to every design.
Automated Assembly Compatibility
Follow the selected connector operating instructions for insertion, locking and removal. Confirm actuator clearance and assembly access in the enclosure.
EMI Shielding Options
Specify a shielded construction when required by the system EMC design. Define the ground connection and verify performance in the intended assembly.
Cost-Effective at Volume
Compare quotations using the same drawing, connector selections, tooling requirements, inspection plan and order quantity.

FFC Cable Manufacturing & Inspection Planning
Define the drawing, sourcing and inspection requirements before production
Design & DFM Review
Review part numbers, netlist, orientation, routing and acceptance criteria.
Material & Connector Sourcing
Confirm component availability, material references and supplier documentation.
Precision Cutting & Termination
Prepare cable length, exposed contacts and reinforcement to the receptacle drawing. ZIF/LIF mating does not require crimping.
Testing & Inspection Plan
Agree continuity, insulation, visual and any dielectric checks against the drawing and component specifications.
Define FFC Acceptance Before Production
Document the inspection scope and acceptance limits for the selected cable and connector combination. Test voltages, durations and sampling must be agreed; they cannot be inferred from the cable name.
- Continuity and short-circuit checks against the approved netlist
- Insulation resistance limit, test voltage and duration from the agreed specification
- Dielectric test only at the specified voltage and duration
- Retention check and sampling per the connector instructions
- Visual checks for exposed contacts, reinforcement and damage
- First-article dimensions against the approved drawing
- Required lot identification and inspection record fields

FFC Cable Design Guidelines for Engineers
Key considerations when specifying FFC cable assemblies for your next product design
Pitch & Conductor Selection
Choose pitch and conductor count together with the connector footprint, routing envelope and electrical requirements. Use the public examples below as references, not as a universal availability range.
Define each signal and return path in the netlist. Review ground allocation with the system designer rather than assuming that extra conductors guarantee EMI performance.
Bend Radius & Routing
Static bending forms the cable during installation; dynamic bending repeats during service. Obtain the permitted routing radius from the selected cable supplier. No universal thickness multiplier is stated here.
Keep bends and strain away from the terminal and stiffener transition. For repeated movement, specify an FPC designed for dynamic flexing or a dedicated dynamic FFC and obtain supplier qualification for the actual motion.
Shielding Considerations
Decide shielding from the complete signal path and EMC environment. Interface names or clock frequency alone do not establish whether an unshielded cable is suitable.
Specify shield termination and ground connections in the system EMC plan, then validate the assembled product.
Connector & Locking Selection
ZIF and LIF describe insertion-force arrangements; top and bottom contact describe the mating face. Flip and slide locks have different operating motions. See the manufacturer references below.
Select retention and vibration performance from the exact connector specification. A LIF label alone does not establish better vibration resistance. Check the footprint, actuator access and cable exit direction.
FFC Public-Specification Reference & Ordering Checklist
Public manufacturer specifications checked for this reference. These are part-specific examples, not factory capability ranges, customer results or a declaration that the example cables mate with the example connector. Confirm the current drawings for the ordered parts.
Contact orientation: specify exposed faces at both ends
Same-side and opposite-side describe the exposed conductors when the cable lies flat. Molex 15266 calls them Type A and Type D; Würth WR-FFC calls them Type 1 and Type 2. Use the manufacturer designation plus an end-view drawing; do not assume a universal Type A–D naming scheme.
| Public cable example | Pitch / circuits / length | Exposed contact faces |
|---|---|---|
| Molex 152660029 | 0.50 mm / 4 / 30.00 mm | Type A: same side |
| Molex 152660030 | 0.50 mm / 4 / 30.00 mm | Type D: opposite sides |
Source: Molex 15266 series chart — exact part rows.
Source: Würth WR-FFC — Type 1 / Type 2 definitions.
Top contact and bottom contact describe the connector contact location relative to its mounting plane, not the cable type code. Check each exposed face against its receptacle in the installed routing, and verify pin order separately. Matching pitch alone is insufficient.
Stiffener thickness: use the finished terminal stack
Specify PET or PI reinforcement as required by the selected construction, its location and adhesive. Total terminal thickness = local cable base stack + stiffener; include adhesive once. Do not add the stiffener to the insulated body thickness if that body stack differs from the stripped end.
Hirose FH12 recommended FFC construction: 0.107 mm local base stack (including adhesive, calculated as 0.295 − 0.188) + 0.188 mm polyester stiffener = 0.295 mm total. This falls inside 0.30 ± 0.05 mm (0.25–0.35 mm). A 0.250 mm stiffener would give 0.357 mm, outside that range. This is a datasheet calculation, not a measured build; the Hirose FH12 specification governs. Check the finished thickness tolerance, not only its nominal value.

Connector fit: pitch, width, insertion and lock
| Interface check | Verified example / acceptance basis |
|---|---|
| Pitch and contact span | Hirose FH12, 0.5 mm horizontal interface: pitch 0.50 ± 0.05 mm; contact span A ± 0.05 mm. |
| Cable width | Same interface: width B ± 0.07 mm. The 20-contact row gives A = 9.5 mm and B = 10.5 mm. |
| Insertion depth | FH12: insert fully, parallel to the PCB; exposed conductors face down for bottom contact and up for top contact. Close the actuator while keeping the cable seated. Use the selected drawing for the insertion datum; exposed length is not insertion depth. |
| Flip lock | FH12 uses a rotating ZIF actuator. Lift to release, seat the cable, then rotate closed; follow its handling precautions. |
| Slide lock | Molex Easy-On Slider series: open the slider, position the cable, then push the cable and slider into the connector. Use the exact series instructions. |

ZIF means zero insertion force; LIF means low insertion force. These terms do not specify which cable face is contacted or prove vibration retention. Confirm the contact side, latch motion, terminal plating and permitted cable geometry for the exact part.
Cable dimensions and bending: keep supplier conditions attached
Molex PS-15266-001 Rev. G distinguishes the insulated body from the reinforced connection area. The figures below belong to that family specification; they are not general FFC ranges. Confirm the individual sales drawing, particularly where a catalogue part differs from the family coverage.
| Parameter | Molex PS-15266-001 Rev. G reference |
|---|---|
| Pitch / cable width | 0.50 ± 0.05 mm / W = 0.50 × (N + 1) ± 0.06 mm; N is conductor count. |
| Body / connection-area thickness | 0.27 ± 0.05 mm / 0.30 ± 0.05 mm. |
| Exposed / reinforcement length | 4.00 ± 0.80 mm / 8.00 ± 2.00 mm. |
| Reinforcement tape | Polyester plus adhesive, 0.15 mm nominal; this is not the finished terminal thickness. |
| Flex-life requirement | At least 50,000 cycles at R = 10 mm, 100 cycles/min and 23°C. Supplier specification requirement, not a result measured by this assembler. |
Source: Molex PS-15266-001 Rev. G, sections 2.2, 2.3 and 3.2.
Static bending means forming the route during installation; dynamic bending means repeated motion in service. For dynamic duty, select an FPC designed for that motion or a dedicated dynamic FFC, with supplier-qualified life at the actual radius, stroke, speed, temperature and loading. An FPC label alone is insufficient.
The cited flex test radius is a test condition, not a universal minimum bend radius. Obtain the static routing limit and dynamic qualification from the selected cable supplier. Keep strain away from the connector and stiffener edge. No unsourced thickness multiplier or lifetime guarantee is used here.
FFC ordering and inspection checklist
Unfilled planning checklist: record requirements before ordering, then add actual inspection observations. It contains no test results.
| Item | Specify / inspect |
|---|---|
| Pitch | Cable and connector part numbers, pitch tolerance, contact span and cable width against both drawings. |
| Conductor count | Count at each end and approved netlist, including signal and ground assignments. |
| Overall length | Length datum, tolerance and installed routing allowance. |
| Exposed contact orientation | Same-side or opposite-side end views; connector top/bottom contact; pin order at both ends. |
| Stiffener position and thickness | Material, side, coverage and adhesive; local stack and finished terminal thickness including tolerance. |
| Terminal length | Exposed conductor length, reinforcement length and insertion datum; verify full seating before locking. |
| Shielding, if present | Construction, ground termination and clearances; confirm compatibility with the connector. |
| Continuity / insulation tests | Netlist, open/short criteria, insulation limit, test voltage, duration and sampling; record observed results only after testing. |
Apply the stricter applicable cable/connector limits and any loading derating. Working voltage is not the dielectric test voltage. Require part-specific compliance documentation where needed; the reference tables do not certify the assembly.
