Micro Coaxial Cable Assembly
Custom micro coaxial cable assemblies for compact medical, imaging, display, and robotics applications where fine-pitch termination and stable signal performance matter.
Micro Coaxial Applications
Micro coaxial assemblies are chosen when signal quality, cable density, and routing space must all be managed at once.
Medical Devices
Ultrasound probes, patient monitoring, endoscopy, and imaging systems
Display Interconnects
LVDS and eDP signal links in compact displays and embedded systems
Test & Measurement
Miniature shielded signal paths for instruments, probes, and fixtures
RF Miniaturization
Short-run miniature coax links where routing space is extremely limited
Robotics
Compact routed assemblies for moving subsystems and tight cable paths
Imaging Systems
High-density camera and sensor assemblies with controlled signal behavior
Assembly Options
We build around the cable construction, connector system, and installed routing envelope your program actually uses.
Built For Dense, Sensitive Cable Paths
Micro coaxial assembly work is less forgiving than standard cable processing. Conductor size, shield handling, strip length, and strain relief all have a direct effect on yield and long-term reliability, so we build the process around the real connector geometry and routing conditions.
- Material selection based on bend radius, impedance target, and insertion space
- Fine-pitch preparation with controlled strip dimensions and conductor exposure
- Microscope-assisted termination for miniature contacts and dense connectors
- Shield management to protect isolation and preserve signal integrity
- Strain relief using heat shrink, tape wrapping, adhesive, or overmolding
- 100% electrical verification plus visual inspection before shipment

Custom Micro Coaxial Cable Assembly For Compact Electronic Systems
As a specialized micro coaxial cable assembly manufacturer, OurPCB builds miniature shielded interconnects for systems that cannot tolerate bulky cable routing. These programs are common in medical devices, compact imaging systems, embedded displays, and precision instruments where signal paths must stay organized inside very limited space.
Compared with a general coaxial cable assembly, micro coax designs require much tighter control over cable preparation, shield termination, and connector alignment. The underlying cable construction still follows the same shielding principles described in the coaxial cable reference, but miniaturization makes workmanship and fixture design more critical.
Many micro coaxial programs are also tied to regulated or specification-driven industries. We align assembly planning with documented quality requirements, inspection criteria, and traceability expectations so the finished cable supports the broader device validation workflow. For customers building to recognized quality systems, standards bodies such as the International Electrotechnical Commission and UL are often part of the compliance landscape we design around.
We also support transition zones where micro coaxial lines break out into grouped harness sections, board-level terminations, or connectorized subassemblies. That makes this page a natural fit for programs that also require LVDS cable assemblies, shielded cable assemblies, or downstream overmolding for reinforcement and strain relief.
When the miniature cable path terminates into a compact RF connector rather than a board-level or fine-pitch signal interface, our MCX cable assembly page is usually the closer commercial match because it focuses on miniature 50 ohm connectorized leads rather than bare micro-coax handling alone.
Every micro coaxial assembly receives 100% electrical verification before shipment, and we adapt fixturing to the exact pinout and connector family in use. If your project involves high channel density, small bend windows, or repeated service access, we help optimize the cable construction early so production yield and installed reliability stay under control.

From the Case Bank
A European thermal imaging OEM experienced a critical production halt due to high impedance defects in a micro-coaxial cable assembly used for a beta production series.
1296 out of 2000 units of AWG#40 CABLINE-VS 1:1 100mm micro-coax assemblies failed due to high impedance, leading to order cancellation, a demand for refunds, and a major trust deficit.
Halted production immediately and conducted joint technical analysis with the customer's engineering team to identify the root cause (specification definition and testing method mismatch). Updated specifications, provided new test reports, manufactured new samples, and processed a replacement order for the defective units.
Successfully resolved the quality complaint, secured a replacement order for the 1296 defective units, and maintained the long-term partnership despite the severe initial defect rate.

Micro Coaxial Cable FAQ
Micro coaxial assemblies use much smaller cable constructions and much tighter termination tolerances than standard coaxial cables. They are typically chosen when routing space, cable weight, connector pitch, or signal density makes conventional coax too large.
Yes. We support micro coaxial assemblies for medical, imaging, and instrumentation programs where compact size, shielding, and repeatable assembly quality are critical. We can also support documentation and inspection requirements aligned with regulated manufacturing environments.
Yes. We manufacture custom breakout sections that transition micro coaxial cables into board-level connectors, miniature plugs, or grouped harness sections. Strain relief and routing are designed around the actual installed space, not a generic cable form.
Every assembly receives 100% electrical verification such as continuity, short detection, isolation, polarity, and fixture-based pinout checks. For critical programs, we can align inspection and test documentation to your validation plan.
