Coaxial cable assemblies are specified by electrical performance and mechanical fit at the same time. The center conductor, dielectric, shield, jacket, connector interface, and termination process all affect loss, shielding continuity, service life, and sourcing risk. FlexiPCB supports custom coaxial cable manufacturing for antenna leads, RF jumper cables, automotive telematics links, test fixtures, and equipment-level cable sets. We handle connector sourcing, cable preparation, crimp or solder termination, overmold and strain-relief options, labeling, and 100% electrical verification so your procurement team can compare prototype and production options on the same controlled revision.
Wi-Fi, GNSS, LTE, 5G, and private-radio modules need coaxial jumpers that preserve impedance while fitting tight mechanical envelopes. Buyers typically send connector stackups, cable length windows, and mating-cycle expectations so the sample build matches the final enclosure instead of only the bench setup.
Vehicle RF and high-speed video links often need compact connector families, abrasion-resistant jackets, and labeling that survives line-side handling. Programs involving FAKRA or other keyed interfaces benefit from connector-code review before release because one incorrect housing choice can delay the full harness or module build.
Gateways, sensors, machine radios, and remote I/O products use coaxial cable assemblies where shielding continuity and bend control matter more than the lowest piece price. The right build plan reduces intermittent faults caused by poor strain relief, underspecified cable, or inconsistent connector termination.
Medical imaging, monitoring, and lab systems rely on coaxial interconnects with documented revisions, controlled packaging, and repeatable workmanship. Procurement teams usually need sample approval, lot traceability, and electrical test records because a cable issue can block system validation even when the electronics are already qualified.
Custom coax assemblies are also used in validation racks, service kits, and production fixtures where exact length, connector orientation, and replacement labeling matter. These builds move faster when the RFQ includes the mating hardware, expected service environment, and the minimum spare quantity needed per release.
Send the drawing, connector part numbers, cable family, impedance target, shielding requirement, quantity, and application environment. Our engineers review missing inputs before quotation so pricing reflects the actual build instead of later assumptions.
We confirm connector compatibility, cable construction, jacket material, and strain-relief approach against your mechanical space, vibration exposure, and routing path. If sourcing risk exists, we flag alternates before sample release instead of after purchasing starts.
Prototype assemblies are produced to the approved revision for fit, routing, and electrical verification. Sample feedback is folded into the production work instruction so the qualification build becomes the release baseline, not a separate undocumented one-off.
Once the sample is approved, production follows the same connector, cable, and labeling specification. Every assembly goes through continuity, short-circuit, insulation resistance, and pinout verification before packing to reduce startup delays at incoming inspection.
Finished cables can be shipped bulk, unit-packed, or kitted for the line with customer labels and lot traceability. The return package can include manufacturability feedback, lead-time options, and test-document expectations so procurement can place repeat orders with fewer engineering loops.
We review connector fit, cable type, shielding, and revision data before quotation so buyers can compare realistic options instead of discovering risk after the sample order.
Many products combine coaxial leads with FPC tails, flex PCBs, or broader cable assemblies. FlexiPCB can support those neighboring interconnect types under one supplier relationship when the program needs it.
The quote package is designed for purchasing teams that need price, lead time, tooling assumptions, sample timing, and test coverage spelled out before they issue the PO.
This service is best for custom production coaxial assemblies, cable sets, and OEM releases. Ultra-high-frequency laboratory phase-matched programs with specialized RF certification beyond the standard electrical test plan should be reviewed case by case before commitment.
Better input data reduces quotation churn and avoids connector or impedance assumptions.

The fastest RFQ includes the connector part numbers on both ends, required impedance, target cable type or outer diameter, finished length, quantity, and the application environment. A simple cable sketch is acceptable if the drawing is not finished. When one of those items is missing, the quote usually turns into an assumption-based sample, which increases the chance of a second revision after fit testing.
Yes. We support both 50-ohm and 75-ohm coaxial cable assemblies when the connector family, cable construction, and end-use requirements are clearly defined. The important point is not only the nominal impedance but the complete stack of cable, dielectric, connector geometry, and installation path. Buyers should state whether the build is for RF communication, video transmission, telematics, or instrumentation so the correct cable and connector pairing is quoted from the start.
Choose coaxial cable when the signal path depends on controlled impedance, shielding continuity, and connector geometry that suits RF or video transmission. Choose an FPC pigtail when space, weight, and fine-pitch board integration are the primary constraints. Choose a broader wire harness when the program is mainly power and discrete signal distribution rather than RF performance. Mixed products often use more than one of these interconnect types in the same assembly plan.
These external resources help engineering and procurement teams align cable selection, impedance expectations, and connector choice before RFQ release.
